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.

2009 World Finals...SCTA-BNI

Mike Geokan's Bonneville Bullet returns to Bonneville for Long Course (200 mph) licensing at the 2009 SCTA-BNI World Finals October 2009.

Bub Meet/ USFRA Meet

With new rider Bryan Stock, while Mike Geokan recovers from medical issues, the Bullett is making tuning passes at the 2009 Bub meet prior to returning to competition in SCTA-BNI events . USFRA and SCTA-BNI share the same records, rules and licensing procedures. As always, you are at the mercy of weather...and it changes quickly at the salt.

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 Amazon.com 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 Callaway...you 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.

There aren't any shrimps on the barbie..Sorry mate!

There still exists a place where critters will kill you and people are serious about their bikes...a place where people like Jeff Richardson toil around the clock to create art that people ride. Art that doesn't get trucked to Sturgis for park and talk sessions in comfy motorhomes. There still is such a place, and it is far, far, away. Down Under.

Newly Redesigned Harley Turbo Kits

We have turbos for small motors and turbos for big motors. We have turbos for stock frames and we have turbos for custom frames. We have center mount turbos and we have left side mount turbos. We have turbos for street and we have turbos for racing. We have turbos for gasoline and we have turbos for methanol. We can run dual fuel strategies with gas and methanol at the same time. We can set the bikes up with two or three or four injectors with injectors rated up to and beyond 1600cc/minute. We have fuels pumps for 250 horsepower. We have fuel pumps for 500 horsepower and we have special pumps for alcohol. We have water injection systems for high output horsepower increases.

We have turbos with different primary tube sizes for different displacement motors. We have turbos to fit standard port cylinder heads as well as S&S SA and S&S B2 raised port, four bolt heads.

Intercoolers either twice or four times as big depending on the application. 10 years ago we made the small intercooler in the center. Newer items to left and right.

All turbos for 2006 are double ceramic bearing. All turbos are capable of way, way, past 200 horsepower. Racing turbos are rated at 600 hp.

All systems use RB Racing's proven RSR Closed Loop Fuel Injection system. Systems are programmed for 2 Bar or 3 Bar operation. All systems use our billet Boost Master Wastegates with pneumatic controls.

We are finishing up on all new instrumentation packages, the most advanced in the industry, to support our turbos. New digital displays. New Boost Gauges. Waterproof, Harley-proof. All to provide vital information.

We can provide Turbos Pods with ORCA engines in custom frames. We also provide Pro Gas systems for big displacement drag racing, speed, and dyno contest engines. We have engineered out seven new systems. One hell of a lot of work.

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. Mandatory 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.
