Wheelsmith Racing has been tuning long before 1980 and on a
National Level, since the 1986 / 1987 Suzuki Cup Series when our own Iain Pero
won and placed 2nd on both the National 750 and 1100 Suzuki Cup classes held at
In the late 80's, Wheelsmith Racing helped build and tune as many as 7 of the top 10 AFM championship bikes.
Wheelsmith Racing / Factory Pro has provided technical services / tuning components for every large Japanese motorcycle USA importer at one time or another and have had the good luck to have been able to provide technical services and / or dyno work with the EC997 dyne systems to others, including

Wheelsmith's 30+ years of understanding fuel injection and carburetor
tuning for the rider is part the result of the founder, Marc Salvisberg's,
background in racing. (I was about "almost good enough" a
rider, but -. Marc :-)
In the early 80's, he was swapping wins in middleweight production, winning lightweight production and top 2-3 in Open Superbike at Sears Point / Infineon Raceway. He and Kenny Roberts did the testing for Fox Racing's early roadrace and flat track suspension.
Understanding what works best for a rider is far from "tuning to an air fuel ratio" and requires a special high speed. low inertia dyno to perfectly tune that part throttle smoothness that is absolutely required for quick riding (and smooth cruise in town :-)
As far as tuning, not only is fine tuning required for
smoothest running, the high speed EC997 dynos feature a 4 or 5 gas EGA for highly accurate
analysis of exhaust gases. This allows the tuner to not only tune for best
smoothness, it also allows the tuner to pick out the throttle positions and rpms
that one uses on the highway and gently lean just those areas for maximum
mileage. We've retuned a fair amount of bikes that the owner's only complaint
was poor mileage - and delivered back a bike that improved mileage as much as
10% along with significantly better power and response.
So, if you've already had your bike "custom tuned" to an AFR, and your mileage is less than desired, maybe we can retune it beyond "AFR" tuning standards and get you better mileage and better performance.
All it takes is a $80 diagnostic dyno run with our 5 gas EGA to see if we can help.
Listed in Rates and Applications are some tuning systems that we have used. The pricing is dependant, to a large part, on the ease of fine tuning and software usability.
It is assumed that the "tuning device" is installed and running.
