Steve Johnson Racing has been racing NHRA Pro Stock Bikes for over 20 years. We have the facility and know how to do whatever you need done to your motocycle. From a dirtbike valve job, to a full customer sport bike with a 360 kit and full race engine; we work on cruisers and drag bike conversions.

A Dyno Session is a real and high tech way to check the horsepower your engine puts out to the rear wheel.  It’s kind of like a doctor using a stethoscope and an EKG to see how good your heartbeat is.  For $100 Steve Johnson Racing will put your bike on our brand new top of the line, Dynojet 250 Dynamometer.  We also have a state of the art Dyno room that will recreate real world conditions.  In fact it’s the same dyno room that we test our 300 plus Horsepower NHRA Pro Stock Suzuki GSXR in.  This test will give you Horsepower, Torque, and Air/Fuel Ratio all on one piece of paper with colored graphs and the peak numbers for each reading.

For you serious guys, and of course some extra dyno time, we can add a few tweaks and adjustments to gain some additional horsepower.  The first thing would be a K&N Performance air filter and then maybe a 4 into 1 header.  If you have the time, and you have Electronic Fuel Injection (EFI), we will install a Dynojet Power Commander and “Map” your fuel curve.  This will give you a steady air fuel ratio and produce the maximum amount of power your bike can put to the ground. If you have carburetors on your bike we move to jetting and slide control. 

Everyone knows, speed and power cost money (try racing in the NHRA Pro Stock Bike series for a year or two).  So if you have the money, we can find and give you the power.  In either case, with carburetors or EFI, you will not believe the difference your engine running right will make on the fun you will have with your new power.


So until we meet, stay tucked and under the paint, because that’s all you have to save power until you have been “Tuned Up” by our Dynojet 250 dynamometer.
