Don Guhl No Longer Tuning Motorcycle ECUs

[Randy B]

That's the EPA causing this. They have been fining various business that have been tuning, or selling parts that they deem to be for the purpose of circumventing emission controls.
It's a shame because the EPA wants to prevent people from modifying any vehicle that ever had a VIN, even is that vehicle is to be never used on road ever again.
In other words if you want a racecar the vehicle and engine can never of had a VIN...period.
If they are allowed to continue with this path, the entire parts aftermarket industry is doomed and a lot of people will be put out of work.
Billions of dollars will be flushed down the toilet in an instant.
