NHRA 2015 Winternationals...Harleys

Six Top Fuel Harleys wowed the crowd at the 2015 NHRA Winternationals. No points, just the invite to stir up interest for the crowd-pleasing Top Fuel Harleys at major NHRA events. Competition Motorcycles, Boise Idaho's Top Fueler. Craig Pelrine driving.

Ray Price's Top Fuel Harley ran a 6.3 second 229 mph quarter mile. Spectators swarmed the bike pits between rounds. Many had never seen riders going 200 mph on one wheel before. The common spectator question in Competition Motorcycle's pit was "Where do you find anyone who will ride these things?".

John Stein Author

John Stein, the author of these two motorcycle books, stopped by RB Racing to talk about racing, mutual acquaintances and to sell books. Now John could have written a romance novel, a book about adolescent wizards or even a nouvelle cuisine tome and made more money. Unfortunately for him and, fortunately for all of us, John took the time and effort to document a past that is slipping away all too fast by interviewing those left alive from the 1950's, 60's and till present to get the rare photos and background color before, as they say...the dust turns to dust. Mindless shopping malls have chewed up the dragstrips and these days people Twitter and Facebook away instead of getting drunk, raising hell, turning wrenches and manning welding torches. Instead of making things, people just buy things...that's the downfall of everything.

Everyday is a beginning of the good old days for each new generation. There are pioneers however... People who rolled the dice in a game that had no payout and the road was hard and untraveled. Obsessions go on for decades. John Stein is obsessed and we thank him for his efforts. Sixty plus years of drag racing and highly-documented (Plus DVD) Bonneville streamliner saga.

A video of John wheeling the famous Clem Johnson Vincent "Barn Job" into his living room is worth a watch on YouTube. The question for all of us is..."Would your significant other let you keep drag racing motorcycles in the living room?". TV sucks these days and the faint smell of nitro, bean oil and sculpted metal trumps sitcoms, and endless Viagra commercials. As they say Nitro is for racing and gasoline is for washing parts. Reality is made, not bought. Appreciate it. John has done a great job of documenting the golden era of motorcycle drag racing in his book.

John gave us a good deal on his books so we bought some and if you have a good story we might give you one. If your story sucks we can still give you a good price. The money goes to our Bonneville Bullett effort. You can also get them from John. Read them, then decide if you want to make history yourself. We are trying. $50.00 shipped.

Russ Collins Passes Away

We first met Russ Collins in 1974 and Russ took us out to the shop floor of his business on Main Street in Gardena to sit on his triple, the "Atchison Topeka and Santa Fe" pictured above. Fast forward to 1977 and Russ sponsored our Bol D'Or Kawasakis Z-1's in the form of hard race parts...cams, pistons etc. He told his general manager Terry Vance to give us "whatever we wanted". When the race was over with we repaid Russ by prototyping his Honda CBX 6-2 exhausts as well as his XS Yamaha three and four cylinder exhausts as no one in his shop really wanted to do it. We hot-wired his personal "RCBX" license plate CBX and ran it about 2000 miles...Russ grimaced at that one.

In the early 1980's Russ decided to expand his operation as he was selling about 2500 exhaust systems a month and Terry Vance and Byron Hines, his employees, were winning Pro Stock. Russ invited us to see his new 45,000 square foot building one Friday...He had put in full custom bar in his office and was full of enthusiasm for the chance he was taking on a major expansion. Come Monday and Terry and Bryon were gone along with Roger McPhail (sales) as well as other key personnel. Vance and Hines was born the next week. They took Suzuki's Pro Stock sponsorship with them.

Russ innovated drag racing and took it to a new level. White leathers and showmanship. Doubles, triples, rear engine, V8's, supercharged 4 cylinders, 4-1 exhausts, Cobra motors, Weber carbs, aluminum Golden Rods, zoomie nitro headers, Hilborn injectors, Magnetos and the victory cigar. Vance and Hines learned while working for Russ and took the model on the road for themselves. Russ once went through the lights at about 170 mph without a motorcycle, ended up in a wheelchair, and then climbed on his V8 Sorcerer. The rest is history as they say.

Russ went on to gain world-class status with his Fuel Injector Business and was the first to put in advanced testing and flow equipment for both fuel injectors and fuel pumps. Russ closed down his motorcycle operation and kept his hand in racing by driving Bill Miller's Top Fuel Dragster. Russ was always a racer first and businessman second. He retired a number of years ago to Palm Springs where he played golf everyday.

Russ passed away during a trip to Hawaii...not in an assisted living facility or a wheelchair. He was 74. Cancer finally got him but no one got him at the XMas tree. He was called "The Assassin" for good reason. A nice guy and technically very, very, smart. Glad we knew him.

2013 Las Vegas Top Fuel

Breathing Nitro fumes and running 6.53 and 204 mph Carl Pelletier and Steve Heidner are back at Las Vegas.Only a few races on the West Coast these days. Fifteen Top Fuelers to entertain the crowd. Addictions are expensive.

46 Years Later..RVN 1967 to 2013...196 mph Bonneville Record

Bob Bennett is a long time Bonneville competitor, holds a number of records, is knocking on the door on a 200 mph record, and has the distinction of having his name engraved on the Viet Nam Memorial Wall as KIA even though he is quite alive. In 2013 Bob has dedicated his new record to the 32 men who died in his unit.. Alpha Company.

Bob hit a peak speed 203 mph with his normally aspirated 1650cc class Sportster. The GPS Speedo's first red light illuminates at exactly 200 mph with the digital display's memory displaying the exact peak mph reached during the run. Bob hit 203 mph without a turbo or supercharger.

Bob writes: "Attached are a few pictures of my bike at speed week last year. The tail section has the 32 names of the men in my Company that were KIA in 1967. The bike number 3399 represents 3rd Bat 39th Inf. 9th Ind Div. Bob Bennett"

They say adrenaline sears major events in your memory that makes them so clear you relive them over and over again. As you get older the short term day to day crap gets less important and fades quickly. Bob returned to Viet Nam recently to retrace his path and to pay honor, by way of remembrance, to those who were with him that died.

Bob got rained out in 2014 as both SpeedWeek and the World Finals were cancelled. He'll be back in 2015. He's ready.

There are a lot of vets at Bonneville. Bennett's Performance. As opposed to Bob Bennett and other vets there are others like Henry Louie below.

Postscript: Henry Ensign Louie

We met Henry Louie via Luftmeister whom we had helped to secure a 200 mph El Mirage record on a BMW. We ended up turbocharging two Suzuki GSXR turbos for which he paid for and one which he did we repoed the second turbo kit. During the time we were around Henry he claimed to be a have been Naval fighter pilot. He also claimed to have his personal F4 Phantom Jet which he flew to St Louis for lunch. He also claimed to be a Korean War veteran flying jet aircraft in that conflict "going eyeball to eyeball with the enemy pilots". He also claimed to have flown the reconnaissance missions over the Bridge at Toko Ri, as seen in archival footage.. When mentioned we had been in Viet Nam in Military Intelligence Henry said he had been in Laos and Cambodia on special electronic warfare sensor projects. For his Harley acquaintances in Boise he also claimed to have been a Harley racer and District Champion in the late 1940's.

Henry, at various times, claimed to have climbed Mt Everest, been a marathon champion and, no matter what subject you brought up he had done it either better, way before you, or he had things which were more expensive or better than anything you had.

We shepherded him into the double two club at Bonneville and El Mirage in his first year of competition, which is pretty much unheard of. We went with him to the SCTA Bonneville awards dinner where he got his double 200 mph recognition and jackets and he did not once mention RB Racing. Henry had to be guided...He could not even remember to turn on his fuel petcock or keep his gas tank full at Bonneville...He was too busy walking around in his Kushitani leathers playing politics and telling stories about himself. Henry wrangled himself to become the President of the SCTA...mostly based on his speed records and his donations of jackets and other items.

Henry ended up selling his Suzuki Dealership (Del Amo Motorsports) and moved to Boise to partner in Big Twin BMW. At his retirement we found out he claimed to have been an admiral. Now if you had risen through the Officer ranks in the Army like we had and our friends had..the claim that Henry had been an Admiral was a bit too much to take so we decided to make some checks. Admirals are North of Naval Captains and Army Colonels. We always knew he was a liar but we wanted to check.

We contacted The Fake Warrior Project and they found no service records whatsoever for Henry Ensign Louie. Our Harley friends at Brother Speed in Boise could find no records anywhere of Henry ever racing Harleys in the late 1940's. Here's a report from the NATIONAL PERSONNEL RECORDS CENTER

Stolen Valor is a crime these days. Henry is now in his mid to late 80's, blind from cataracts and in a rest home in Salt Lake City where he preaches his stories to the staff and residents of his nursing home.


Doc Sweeney: "Trip done: 5950 miles 28 States in 9 days. Bike performed well"

Doc Sweeney and his RB Racing Intercooled TC88 Turbo on a marathon 28 state run. Genuine Pinto gas tank along for the ride. "And miles to go before I sleep". Doc Sweeney covered 4500 miles in the first week.."Running fine". Total 5950 miles in 9 days.Next up...a R1200GS BMW and off to Alaska...all 50 states. The TC88 was shipped in from Hawaii. All 50 States.


New V-Rod Turbos

RB Racing's new V-Rod Intercooled 360 hp turbos. Hey, they have been around for a decade. Like on any Harley packaging and engineering out a proper turbo system is difficult. We started on them a few years back but our racing activities at Bonneville took precedence. We are always booked up with our projects but we robbed some time and finished up our earlier work. Money, resources, time and manpower are always the limit in business. It chews up a lot of all of these to tool up for a new product.

New V-Rod Exhausts

Pectel SQ6M Engine Management

For our racing projects at Bonneville and our own 360 hp Road Glide Turbo we have upgraded to Pectel Cosworth SQ6M Engine Controllers. These offer total control of fuel, spark, traction control, fly-by-wire throttle, wastegates, and anything you can think of. Also, many things you would never think of.


The SQ6M controls the Electronic Throttle as well as our 1000 psi water injection system on our 126" ORCA Road Toad and our 139" ORCA Bonneville motor.

Motorsports Mil-Spec Wiring

We're two-wheeled, not four-wheeled racers and, although we've raced at LeMans on two wheels, these days we go to the Bonneville Salt Flats. Electrical wiring and wiring harness problems are always major issues regarding reliability, so we put togther a resource for those who are contemplating making "mil-spec" wiring harnesses. The Bonneville Salt Flats eats everything on your race and support vehicles.

Our high end race applications use Pectel Electronics and we have to design the wiring harnesses in-house. This involves documenting everything from wire specifications and color codes to each connector and slice point as well as having all the tools and supplies to get the job done. This is expensive, mostly time-wise,  but poor wiring will kill a race effort.

2012 Las Vegas Top Fuel Harley


Joe Smith...The Drag Racing Legend and three time Top Fuel Motorcycle Champion 1971, 1974 and 1975, stopped by our pits to look at the bike and talk to Steve Heidner about what else...Drag Racing. Follow the links to Joe's web sites and see who paved the road in Harley Drag Racing at a time when you made it all work on your own nickel and when you had to make everything yourself...Single engined and double engined. Joe did it all and won. He still loves the sport. Once a champion always a champion.

11 Top Fuel Bikes showed up for the 2012 Lucas Oil event at Las Vegas. The NHRA has expanded it's schedule for the Top Fuel Harleys as they are very popular with the spectators as well as the car drag racers. Follow Steve Heidner and Carl Pelletier at the event.

New LSR 2-1 Pro Stock "RaceCat" Exhaust systems

We are now offering our pure racing LSR 2-1 Pro Stock Challenge systems with a zero-restriction, sound attenuating, RPV Technology catalytic converter that knocks a few decibels off our race systems and mellows, or deepens, the sound a bit at idle and midrange cruise rpms. Called LSR 2-1 Pro Stock "RaceCat" systems, they are the most sophisticated race system that you can use on the street. Like all our systems they are custom made to order.

Newly Redesigned RB Racing Harley Turbo Systems

Left-mounted turbos and right mounted large 360 hp intercoolers..for Evos and Twin Cams (Delphi). We like Road Glides which we call Road Toads....but they just aren't fast enough for us. We get a break from our Bonneville Bullett to introduce these new kits. You can't do both at the same time...and doing stupid things like filling hotel room bathtubs a thousand miles away from home full of beer and eating casino food take precedence.

To take a short 8 psi boost ride on the Road Toad we have posted two short videos on YouTube. The second one shows the full digital instrumentation.

126 ORCA...Building a 360 HP Road Glide

In case you want to see what it takes to build a 360hp Road Glide, we offer a build history of our test bike where we develop new products for our racing activities. A 360 hp couch is a good way to test what you race. We also get to make FLT/FLH chain drive swingarm conversions to hold the 360 hp.

Harley Davidson and the Marlboro Man

We made the exhausts for the movie bike..actually several sets of them while the movie was being planned and finally shot. The bike became sort of famous for some reason. We put up a bit of history of the affair for you to read. No money...just history as they say.

Bob George...Time to Reflect

Bob George crossed our path at a time in the 1980's and 90's when we were setting Bonneville and El Mirage 200 mph records with Suzukis, BMWs, and Harleys. "Bob George" wasn't exactly a household name and we were unaware of his accomplishments. We ended up getting involved with seriously deranged character who had a streamliner project who, in turn, introduced us to Bob George. After we got rid of the relationship with this nut case, who worked for the US Postal system and lived in his Ford Van, we became friends with Bob George and found out about his history at Bonneville.

Above is pictured the record setting double-engined, nitro burning, Shovelhead powered, Jammer Liner...designed and built by Bob George. Business partners Mil Blair and Joe Teresi sort of took over Bob's project. Mil went his way with Jammer Products and Joe Teresi split with control of Easyriders Magazine. Bob George is third from the left. Bob ended up losing the liner...and the recognition.

Years later the same liner was re-skinned in aluminum and rebuilt by Joe Teresi of EasyRiders Magazine. Tech honchos like Keith Ruxton and Micah McCloskey made it go. Dave Campos again was the pilot and 322 mph was the result. Still Bob George's design. 322 mph. Water cooled Barrels patented by Bob George.

Bob George built another liner on his own dime, the "Millenium Falcon", and we built the "robo-skids" for it and helped crew it in several trips to Bonneville, again with Dave Campos as the driver. Dave ended up getting a 200 mph gas record with it in testing and, at one point, Don Vesco was to ride it but Don convinced Dave to stay with the project. Bob spent every penny he had on it and finally had to sell it. Streamliners are a fatal disease, financially.

Bob George center in the red shirt. Kent Riches (Airtech) ended up with the chassis and shell. We kept the actual Eagle cum Falcon doll that rode with Dave. It goes with us each year to Bonneville. Mike Geokan ended up with a 93" engine from the last stages of the project and put it in his famous (retired) Blue Bike.

Bob George Rebel with a Cause

Bob George third from left on his double engined Knucklehead. Before reality shows, before Custom Crud, when grease was in your hair and under your fingernails. Guns, bikes, Mary Jane, beautiful girls and a bad boy attitude that was not store bought.

Bob George's side by side Knuckehead drag bike. S&S was making pushrods and Bob George was running Amals before there was an S&S Carb. Spokes.

Bob George..Double Trouble...Back in the day


Ripples in the pond. Glory days. No money, just hard work and good times. Roll your own. No rules, no guidelines no internet, no forums....Just hold her open and see what she'll do.

Bob George 230 MPH Shovelhead

Bob used to kick start his double engined Shovelhead dragster and reel off 145 mph quarter miles...about 40 years ago. Then it went to Bonneville with both Bob George and Dave Campos doing the riding.

Bob George's famous "Double"...231 mph Bonneville record holder in the early 1970's with Dave Campos riding. This bike was fragile but serious. It really got Dave's attention as he didn't really wind it out and the wind was pulling the lightweight fiberglass apart on his record run. Bob George in the white hat. Plywood bracing was added to keep the top of the windscreen from folding over at over 200 mph. Bob patented the water cooled cylinders.

In the late 80's and early 90's we were running 203 mph with our high tech Suzukis, 206 mph with our BMWs, and 199mph with Mike Geokan's Turbo Harley and here Bob George had gone 217 mph unfaired on the Double and Dave ran 231 mph with the fairing...about 20 years before we did it. Bob "lost" the Double for many years and when it was finally returned to him we ended up helping him restore it. Careful examination of it made us feel pretty stupid and made it clear you don't adapt things for build things for Bonneville. Bye, Bye Suzukis...back to pushrod dinosaurs. That's why we are working on Mike Geokan's Bonneville Bullett...another fatal disease.

We were to drive Bob and his ex wife Roberta Linn up to Bonneville in 2010 for Mike Cook's Shoot Out Meet but Bob's health had declined and he passed away in his rocking chair a few months later. We once asked Bob what the Double would run if it was brought up to modern specs...without hesitation he said "275mph"...think about it. It was a honor to work with him and know him.

Leo Hess has the "Double" these days. Leo also got bit big time by streamliners in a major crash in 2010. Salt addiction. Be warned.

Top Fuel Las Vegas 2011

Follow Steve Heidner on the Competition Motorcycles Top Fuel Motorcycle as he qualifies for and races at the NHRA meet in Las Vegas in November 2011.

Bonneville...World of Speed 2011..200mph record

The Bullet returns to Bonnville in 2011 for the USFRA World of Speed, the shorter event hosted by the Utah Salt Flats Racing Association. Here Tom Evans, the head motorcycle inspector is verifying the Bullett's engine displacement to certify the 200 mph record. We have provided a chronology of the event and pictures from the trip. No one was arrested this time.

Mike Geokan's Bonneville Bullett

Mike started buliding his new Bonneville bike, the Bonneville Bullett, over 20 years ago. We have provided a chronology that shows what happens over a 50 year period to go from an idea planted as a young boy, throught the usual messiness called life and the culmination of his dream many decades later after a long bumpy ride.

Vegas 2010...Top Fuel

West Coast AHDRA events are about non-existant in today's economy so, if you want to race and you're on the West Coast, it's about 5,000 miles of driving before you get to the place where you can blow up your toy in search of a small purse. Less people are willing to do this. No Pomona, no Las Vegas, no Bakersfield...only Arizona and Woodburn. To get the NHRA interested in putting on a death-defying, crowd pleasing, nitro noise making addition to their event calendar, seventeen Top Fuelers were organized by Fast Lane Motorcycles to show what bikers can bring to the equation.

Carl Pelletier of Competition Motorcyles went to be part of the show and test some new equipment. Here's some photos.

425 HP Bonneville Bullett Lower End

2010 is the time to completely disassemble Mike Geokan's Bonneville Bullett. Engine, transmission and all components have to be inspected after the runs at Bonneville in 2008 and 2009.

Here Carl is assembling the Bullett's 139" ORCA crankshaft with his unique full complement bearing structure and high pressure assembly lube. No issues were found after all the runs at Bonneville. We weren't going to return in 2010 without inspecting the engine. We are providing a chronology of what it takes to get ready for the 2010 season.

Breaking News

For the latest information in the two wheeled market read the news that will impact your two-wheeled lifestyle in our new Breaking News Section. New Harley models, Harley's recession plans, Buell's disappearing act and the new Harley Predator Drone.

Terry Stewart...Shaker Rods

Terry makes our 8" 139" ORCA Rods from these forgings. There are about a bizzillion steps before they are ready to put in a 400Hp Orca Bonneville engine.

Too bad they are hidden inside the engine because they sure are pretty. If you are a gearhead like us, they certainly are. Give Terry a call for your rod and CP Piston needs.

Pro Stock Power... Black Hole Technology

Bigger engines, more compression, radical cams and the never ending search for power and individuality have exponentially raised decibel levels and eyebrows. The men in Blue have their orders and are now listening for you. Reality TV shows are edited and condensed for consumption. Strife, tension and open exhausts are good entertainment. Perception and reality don't actually have to work beyond the last commercial. Hit the road with your dream and collide with reality. You can't park and talk all your life...or maybe you can.

Performance and a mild dose of acceptability can coexist but it requires original thinking. RB Racing has married their race winning LSR 2-1 Pro Stock exhausts and their silent running LSR 2-1 Black Hole systems to engineer a solution to kicking ass in a society that looks askance at the outlaw. LSR 2-1 Pro Stock Spyder systems. Tested on 120 Hp CNC ported 110" engines as well as lower hp103, 96, and 88 motors.

ORCA GPS Speedometer

On Harleys the speedometer is usually driven off of the transmission. If you spin the tire, change gear ratios, or even change tire sizes the speedometer is no longer accurate. Then there is the issue that the speedometers are not designed for 250 mph or even anything past 120 to 160 mph. This situation is not exactly made for Bonneville where you are running past 200 mph, spinning the tire, searching for traction, and putting 300 mph Goodyear Land Speed Record tires to the test.

We figured the best way out of this was to equip the Bonneville Bullett with a GPS (Global Positioning System) speedometer. When we checked around we found some GPS units for boats but nothing made for a 250 mph Bonneville Harley. The only option was to make a GPS Speedometer. Four satellites will triangulate the Bullett in three dimensional space and Mike can have a dead accurate speedometer that never needs to be calibrated.

Third Time's a Charm...Old Story, New Customer

Customer writes: "Thanks to all involved in my exhaust system.  The exhaust, when dynorun, proved to put out more torque and quicker acceleration over XYZ Exhaust systems I have used in the past and present.  I am happy that I found you and will use RB exhausts forever.  It has the good old Harley sound to it and I receive compliments from those who ride with us. Even people that don't ride with us. THANKS AGAIN.. Ron in Florida"

00-1122 in chrome. People usually buy two ot three exhausts before they get a LSR 2-1. We've been at it for over 30 years and, all we do, besides insane projects that eat everything in sight, is just come in and try to build things we know that work. It's not more complicated than that.

Harely V-Twin Balance Calculator

Setting up a race engine or building your V-Twin from scratch you need to weigh all your reciprocating and rotating components and decide on a balance factor. There is no way these articulated rod 45 degree V-Twins are ever going to be perfectly balanced, but we do need to make a few calculations to make your ride more successful.

R1100RT Turbo Testing

Say you work for RB Racing. Say you get paid to ride around Califonia and test 200 hp Turbo bikes. It gets tiring so, every so often, you need to take a break, make a few notes, have some lunch, hit the usual spots, and visit a few friends. Do some extended cruising at 110 mph and watch the speedo head past 140 mph. All in a days work. We work hard. We play hard. If it's not fun we don't do it.

We always run our initial instrumented tests without the muffler so we can watch the exhaust turbine wheel. When we finish several thousand miles of testing at different altitudes, temperatures we put on the muffled tail section and quiet the thing down to a whisper. We also make a short dump pipe for racing.

In case you are wondering...It is damn fast. On pump gas with a bit of Toluene we run it up to 185 hp @ 15 psi. For 25 psi and 240 hp we put in Race Gas. Our test rider has more than one million miles of road work and has ridden lots of high end turbo drag bikes. He knows how fast it is. Other bikes don't. iPhone3Gs.

BMW Clutches

OEM BMW clutches are automotive style dry plate with solid, unsprung, hubs. Because of our racing history with BMWs we have developed a line of K Series and R series clutches that meet the needs of Street, High Performance, and Racing Applications. We have addressed the thorny issues of spline damage, slippage, and ultra high horsepower clutch destruction. We're testing these on high end turbo systems before we release them to the low horsepower crowd.

Coating Technology...401 mph 4 cyl, 436 mph 8 cyl

Alan at Xtreme Performance Heat Coatings is the guy we go to to do our coatings. All our Bonneville projects as well as high end efforts like the Speed Demon pictured above go to Alan for their coating work. Ken Duttweiler's engine work is destined for an attempt at 400 mph with a four cylinder engine. The team made an exit speed of 401 mph with an average of 396 mph. Speed Demon. At the 2009 Bonneville Mike Cook Shootout the car ran 436 mph with an 8 cylinder engine.

Smokey Yunick..Innovator, Racer and More

These days people just buy parts and "go racing". They argue endlessly about "this and thats" : Which cam to run; Which cylinder head specialist to use; or who should do this or that for your project. Smokey did it all, and, along the way, left a trail of brilliant innovations and a reputation for original thinking that endures to this day. These days people have given up on learning and innovation and endlessly leaf through catalogs blissfully unaware of the underlying fundamentals. Drop out of school because it's too hard and skip the school of hard knocks...just remember because you were born you're "due".

As time passes, rules and organization strangle innovation and original thinkers. Run whatca brung philosophies are being left to street racers and places like Bonneville. For an interesting short read on Smokey we suggest a Circle Track article about the early NASCAR days.

Why go to Mars when you can sit in front of your widescreen and watch the Disney Channel? Better yet, read some unedited (not cleaned up) books on Smokey's life.

Buy the Damn Book...Or steal it if you're wearing tennis shoes

If you want to enjoy some history we suggest you purchase the three volume set of Smokey Yunick's chronicles of his long racing career and life. There aren't many original thinkers around and most of them don't do a damn thing. Smokey was different and a genuine legend in American motorsport history. If you just happened on the scene we suggest you buy his books. It's the most entertaining and best investment you'll ever make.

Buy the books!!!!

RSR Bonneville Gear Indicator

If you’ve ever tried to shift into high gear when you were already in high gear, or any one of those times you simply were in the wrong gear at the wrong time, you will understand the need for a digital gear display. You can’t look at gear shift because there is no “H” pattern, no blinking skull, only a little lever down by your left foot that is spring loaded to go back to the same point after every up or down shift. 1N23456...5432N1...23456 ad infinitum.

Knowing the gear you are in makes your driving faster, safer, and more efficient. Less mistakes is always a better deal. We got frustrated with the lack of a suitable digital gear position indicator so we made one.

2" Shovelhead Pro Stock

We hand make all our LSR 2-1 Pro Stock systems but a 2" Shovelhead requires a lot more work. Sort of an odd request, but this one is for a long term customer of ours who has set numerous records with Shovels with our exhausts and is now planning to go to Bonneville with a built 113". The pipe is a 2" LSR 2-1 Pro Stock 00-1381 and is headed off for a Silver Ceramic finish. Customer runs a ported Super"D" with Thunderjets and a ram air system.

You can't get a 2" pipe at the ports as we can on our other systems so we have to "bell" the 1 3/4" into the 2" primaries. Front primary slips and the exhaust is designed for the taller engine. The customer asked for O2 ports so we installed them.

Go see the movie if you can find it showing somewhere on a large screen. It is spectacular. It is also out on DVD and available from sources like For more detailed info on Burt Munro and his Indian.

New BMW R100 Black Hole Exhausts

From the early 1980s up to about 1995 we made thousands of BMW exhausts and hundreds of BMW R series turbo systems. We are now offering advanced technology systems for the older BMW "Airheads". Soon to come are closed loop efi systems and upgraded turbos.

R1100RT/R1150RT Exhausts and Turbos

Pro Stock Spyder and LSR 2-1 technology brings new life to BMW's pushrod V-Twin. Intake modifications, computer upgrades, and high performance clutches bring performance to a world full of bar backs, Garmins, and do-nothing carbon accent trim.

Take your BMW R1100RT or R1100S and add 150 additional horsepower....or just another 50 horsepower if that's enough for you.

Bonneville Porting

Whenever we do something serious like our 139" Bonneville ORCA motor we defer to the experts, especially when we are dealing with raw, unfinished ports the size of a dime. Branch O'Keefe is simply the best in the business and even Jerry Branch (retired) got involved in the decision making. Take a look at some ports that about 90 years cummulative experience came up with. All John O'Keefe and Jerry Branch asked was what we thought the exhaust ports should be like in terms of flow based on our 30 years of turbocharger experience. We all agreed on a number and this is what the result was. Ports for 400+ horsepower.

If you want the best cylinder head work for your Twin Cam, Evo or even Shovelhead contact Branch O'Keefe. That's what we do and have done since 1976 when Jerry prepared our cylinder heads for the 24 hour Endurance racers we built and took to the 1977 Bol D'Or in France. John O'Keefe knows you don't want "down time" so he has an exchange program for cylinder heads. Harley has made a lot of changes in their castings and it's best to go with Branch O'Keefe as differences in machining, alloys, and specifications can cause problems if you deal with porters who don't have the inventory and the experience.

John does not have "homing pigeons" like other outfits where seats come loose, the work is sloppy, or cheap valves that stick or gall are installed. He treats every head they produce as if it was his own. Sort of rare these days. John has a killer setup for 103" Dressers.

"Sly's"...James' new restaurant

James Sly is our long term racing friend and great chef and restauranteur and he's at it again with a new place. He knows everybody in racing and everyone knows him...Jesse Alexander the great racing photographer, everyone at Porsche, VW, Audi, Ferrari and not to mention everyone who's anyone like Steve Saleen, Andy Granatelli, Reeves think of a name and James has been there with them at the races. Then there are all the rich and famous who know James puts out the best food you can get anywhere...people like the late Julia Child who ate at James last restaurant regularly before she passed on...and asked for seconds.

He's been to LeMans..."Le 24 Heures du Mans" so many times with teams, and is so well known, that local French hotels ask him to give their sauciers lessons. Sly has worked at the Hotel Ritz in Paris, Michel Guerard's in the south of France, and was chef at L'Orangerie for a year.

Hell, he even knows us and has for the past 30 years and we're hard core two wheel racers.. He's a multi-facted guy who has long served as a Technical Editor for automotive magazines, caterer to the Peterson Automotive Museum, and even to a short list of politicians and TV and movie people who don't race, and who we give a rat's ass about.

James's new Place is called "Sly's" and if you can make it to California you best make a straight line to Carpenteria which is just a short drive up the coast from Los Angeles. In the rarefied world of great chefs you won't find another one who has such a passion for great food and for racing, or one who can outdrive you. James' new place is open and the reviews are in. We stopped by for lunch and ran into TC Kline as well as Jesse Alexander. Great food, great service. A tougher, more demanding, business than making racing parts. If you're in California make the trip.

New Dual O2 Meters

For EFi sequential injection our new RSR Dual Air Fuel Gauge displays the fuel mixture in both the front and rear cylinders separately. The gauge is housed in a hard anodized round enclosure in a standard 2" format with a 2.250" bezel, center back mount, with a 5/16" x 18 stainless socket head cap screw. The gauge will show fuel ratios from 17:1 to 12.0:1 (or richer). The gauge is visible in daylight and automatically dims for nighttime operation.

Scale is, left to right, lean to rich: three greens, three yellows, two orange and two red l.e.d.s.

The white arrow indicates the maximum power mixture, the second orange light, which is 13.2:1. Transitory enrichments should not, if the engine is warm (>200F Oil temp), go past the first red light. Readings at the far right side of the scale, the second red light, are simply too rich. Proper closed loop operation will cycle back and forth from green to orange around the center of the display.

It is simply the best way to evaluate the tune of your motorcycle and saves valuable dyno time. Mounted permanently. Waterproof.

Compatible with OEM narrowband sensors. Can be supplied with new high temperature Bosch narrowband sensors. Far right photo shows gauge in dim light conditions at maximum power setting.

New ORCA Tachometers

Tachs are an essential aid to tuning, racing and shifting under race or normal riding conditions. Since the 1970's we have been racing in one form of competition or another and have always been pissed off at many of the tachometers that either were "slow", hard to read, or simply fell apart.

We've developed an analog/digital tach that addresses many of the issues we had with previous tachometers. We developed the tach for use on our ORCA motors and as part of an instrumentation package on Mike Geokan's Bonneville Bullett. 3" Diameter.

We also have ORCA GPS speedometers and odometers coming. Have to have these for Bonneville. No calibration, just put them on...0-9999 mph!.

New ORCA Turbo Dash Shipping

Dual Type K Thermocouples, 3 Bar Boost display. Warning lights for oil pressure and water injection activation, all in a 6.5" x 2" billet enclosure. High memory recall, brightness and reset buttons. Switchable between Celsius and Fahrenheit. Laser cut stainless steel front panel. Tested on several projects and on the Bonneville Bullett. Optional on all of our turbo kits. Other digital instrumentation is to follow..all tested in competition.

Laser cut face plate and hard anodized cnc enclosure all in a 6.5" x 2.5" package. Read more about this new product.

2006/2007/2008 Dual O2 Sensor Systems / RSR Air Fuel Gauges

For 2006/2007 The Dynas have dual O2 ports. We have prototyped a range of exhausts for the closed-loop Dyna models.

Since we have been doing closed loop fuel injection systems for Harleys for more than 17 years and have been putting O-Sensor Ports in our exhausts for the same amount of time, we have dual O2 ports for the 06 models for our full range of exhausts. Our RSR Air Fuel Ratio Gauge is the best investment you can make for these.

All LSR 2-1 can be ordered with two O2 ports. Actually O2 sensors are a really neat item. We should know, as we have a lot of experience with them. Tuning strategies are different and there are a lot of things that can go awry if you forget about temperatures, pressures etc.

Pretty soon Harleys will all be watercooled then you really won't be able to tell the difference between Milwaukee and Hammatsu. "The Man" will be sniffing your butt and planting microchips and gps modules up your ass so they can mail you a speeding ticket and keep track of your movements. They already have data recorders on your car so they know what you were doing when the biggie happened. Brave new world.

124 Challenge Pro Stock LSR 2-1

LSR 2-1 Pro Stock for drag racing 124 Challenge class engines. Available for either standard port (two stud) or B2 (4 bolt) cylinder heads. Special merge collector and slighly shorter primary tubes with a short racing 2.5" diameter tail or secondary. Part number is 00-1306. Parts are available in raw finish (see above) or in silver ceramic, black ceramic, ss titanium ceramic or chrome finishes. Please review our exhaust technology page as well as our LSR 2-1 Pro Stock page.

Lynchburg Harley-Davidson has been getting 138hp and 145ft/lbs of torque on 117" TC88 street motors with these exhausts.

Joe Boyd won the 2005 and the 2006 AHDRA S&S Super Stock Western Division Championship with his Challenge pipe on a 113" motor. The pipe dropped his E.T. three tenths.

Records have even been set with Baggers using our LSR 2-1 Challenge Pro Stock Pipes. Danny Arnold from Doc's Harley Davidson is getting 134 hp and 134 foot pound of torque out of his 107" Bagger and set a record in the AMRA Street Dresser Class: 11.471 @ 115.60 mph.

New 2004 to 2009 Sporster LSR 2-1's

Rubber Duckies hit the street. FXR's reincarnated in a smaller package. We have a range of new exhausts for the 2004 to 2007 rubber mounted Sportsters. Harley changed the exhaust flanges so you'll need to pick up a set of older flanges and clips for the LSR 2-1 Venturis. The Harley part numbers for these flanges and clips are: 65328-83 (exhaust ring clamp) and 65325-83A (retaining ring). Shown above is part number 00-1269 LSR 2-1 B Style 1 3/4" Turn Out in Ceramic Black. Yes, those are V-Rod brakes, Buell heads and a Softail rear wheel.

Indian Powerplus 100 and Scout Pipes

We recently prototyped four new LSR 2-1 C Style exhausts for the recently demised "Powerplus 100" Indian 45 degree V-Twin. The engines sort of shuffled the Evo deck a bit, putting the oil pump in the front and the filter where the oil pump was. Then they stuck the carb out the left side. Must have been designed using mirrors.

The chassis are quasi-Softails with a Monoshock suspension.

People had to redo these engines as the Taiwan cranks and the various USA parts didn't get made on the same blueprint. Enough have been straightened out that we are making exhausts for them. The company is gone but the name lives on in the hands of new owners. Stay tuned as they say.

Indian Scout

Customer writes: "I have just sent you some photos of my 2003 Indian Scout .I purchased them through Joe at Jam Limited and could not be more satsified. The pipes are everything I had heard about your product. The fit and the sound and the looks are the best I have ever seen. The wait was a little long but well worth it.  Joe said he had never sold any for a scout so I thought you might enjoy seeing your pipes on yet another model. Thank you so much for a wonderful product. The pipes are so good looking I'm not going to put the heat shields on until I have to.

To order Indian pipes contact Joe Malfa at JAM Ltd (775) 323-9035.


RSR Fuel Injections hold the records and remain the only competition proven closed loop systems developed especially for both normally aspirated as well as forced induction Harley Davidsons. There were the first to set both 200 mph Bonneville records as well as National Pro Gas Drag Racing championships. New ECUs for 2008 maintain the technological lead and offer new features. Waterproof and Harley-proof they cannot be killed.

New Water Injection Calculator

Since 1981 we've been running water injection systems on our race bikes. Water is always a bit of a problem over the long run as it is corrosive and is difficult to meter correctly. Getting it correct requires a bit of reseach. Thankfully most of the research was done 60 years ago on WW2 piston aero engines. We've created a new RSR Water Injection Calculator to take the guesswork out of water injection.

New Professional Rake and Trail Calculator

We have produced a more sophisticated Professional Rake and Trail Calculator to allow you to enter different wheelbases as well as rear tire dimensions and different fork lengths to see what happens geometry-wise. We also have our Advanced Rake and Trail Calculator that will figure out your trail for your existing setup. Sines, Cosines, Tangents, Radians and inverse functions meet a jungle of dom tubing and dreams of the open road.

Bonneville Bullet

At the start of a long gestation project: Carl Pelletier, Mike Geokan and Brian Stock with the infamous Blue Bike #226 and the new Bullett. Here it was before we had Mike alter the frame for the 139" ORCA engine. The project is nearing completion. Many new specialzed engine parts, electronic instumentation packages, data acquisition equipment and water injections systems are in place for testing in early 2008. Check out Mike's progress from 2008 up to present day. It's a long journey.

The Bonneville Bullett has a separate oil system for the turbocharger which keeps engine oil and turbo oil separate. A timer system allows the engine to be "killed" and the oil pressure to the turbo will be maintained for another programmed amount, up to 90 seconds. A separate oil reservoir has been fabricated with internal baffles to hold the special synthetic turbocharger oil. With shaft speeds of 100,000 rpm and high dollar turbochargers, oil failure is not an option.

Water Cooled cylinders on the 139" ORCA Bullett. To the right is the new 500hp intercooler that we fabbed up for the Bullet. Mike did the rubber isolated frame mounts for the cooler. The turbo discharge enters the left and exits on the right where it heads for the inlet plenum.

Special double ball bearing turbochargers are used on the 139" ORCAS and are rated in excess of 500hp.

Take a tour of what it takes to build a 200mph six second Top Fuel drag racing motorcycle. Join Carl Pelletier as he puts together his pushrod rocketship from bare chassis through the 2002 AHDRA season. We have posted four movies of Carl's progress from his maiden pass with the white bodywork shown above to the first season finale where Jack Romine ran a 6.95 @ 196 mph pass on the fully-painted Competition Motorcycles Top Fueler...and other movies leading to the win in Bakersfield and the last race at Las Vegas.

2004: Bakersfield AHDRA Nationals; Carl Pelletier and crew rack up their first overall win.

2005: Death of a Top Fuel Bike. Watch the movie and see what happens when the rider gets blown off the bike at 208 mph. Cracked wrist, compressed vertebrae, road rash and one crunched Top Fuel Bike. More pictures have been posted in the Top Fuel Section.

Dance with the Devil. Steve came home alive but the Competition Motorcycle's bike didn't. Funny thing about crashes...spectators love to see crashed bikes but other riders are afraid to look at them...Superstition and fear hide in every racer. Organizers ask you to cover up the wrecked bike...Wonder why?

Steve is home, walking around after two skin grafts and a two operations on his wrist. Carl of Competition Motorcycles is back in Boise, busy building race engines, and taking the fueler apart and making an inventory of things to do.

Top Fuel 2 & Nov 2006 and 2007 Update

Watch Carl Pelletier and crew build a new high gear only Pro Fuel Bike. Steve is back in a new set of leathers after his 208 mph tumble in 2005. Four slide shows showing everything from bare frame to first track test. Las Vegas track tests proved successful.


Watch Carl and crew fix this puppy. No, the valve is not supposed to be stuck up in the roof of the inlet port.

2009 Pro Dragster, Pro Fuel and Top Fuel

While his top fuel chassis was being reconstructed Carl Pelletier continued his Pro Fuel Dragster and built another Pro Dragster bike. Here is the new Competition Motorcycles Top Fuel Frame as completed by Weekend Frame Co. Sponsorship from Bardahl has helped.

NHRA Christmas Trees: Simulations to practice Sportsman and Pro Trees.

Driver Reaction Time Tester: Test your reaction times.

This section will be covering drag racing technology and strategy...everything from Top Fuel to bracket racing.

RSR Fuel Injected 113" ORCA / 139" SUPER ORCA Motors

113/126/132/139" S&S Cycle based Special Application ORCA motors in both Turbo and high compression configurations are shipping. With S&S Special Application cylinder heads, forged RSR lightweight pistons, Bonneville record holding RSR Closed-Loop Fuel Injection systems, and up to 350hp, these are the most sophisticated pushrod dynosaurs roaming the earth. 50+ miles per gallon doesn't hurt either. Pictured above is a 113" Turbo ORCA that fits in stock and aftermarket frames.

Pictured above is a full race 139" Turbo ORCA (4 3/8" x 4 5/8") that is being assembled for Bonneville. Fully machined and balanced lower end features 8" McClure Rods with .927" Chevy pins. This motor is to be RSR Fuel Injected, turbocharged and intercooled, and will run in both low compression gasoline and in high compression methanol configurations. Street versions use finned barrels.

For Bonneville, special waterjackets are being readied (see pictures above) to prevent melt-down while under up to six mile long high boost runs that the bike will endure in up to 16 days of actual competition per year. Carl Pelletier of Competition Motorcycles is handling the specialized machining and final assembly along with Mike Geokan.

Street versions of the 132/139" Super ORCA featuring aluminum cylinders will be available for chassis that acept 1"taller engines. 132/139" Super ORCA motors are about 1" taller than stock, so they have to go in aftermarket or race frames. These are the most powerful engines you can buy. All motors feature competition proven RSR Closed Loop Fuel Injection systems.
