RSR Air / Fuel Ratio Gauges...Dyno on your Bike

 

Mount the RSR Air/Fuel Ratio Gauge in plain sight on your Harley, preferably near the tachometer, so you can correlate rpm, load, and mixture strength for accurate tuning whether it's for a carbureted or a fuel injected model. Single Gauge for carbureted, Dual Gauge for efi.

The gauge is waterproof and shockproof and the display is visible in direct sunlight and dims at night.

The gauge case is cnc machined billet aluminum, hard anodized for corrosion resistance, and has a 5/16" x 18 stainless Allen bolt in the center / back to provide a solid mounting point. Optional three degree freedom handlebar mount system and sunshade.
