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.

It wouldn't bother me if it put an end to obnoxiously loud exhaust pipes on motorcycles or cars, but so far i haven't read anything about loud aftermarket exhaust pipes no longer being made or sold.

Having attended MotoGP races, those bikes are insanely loud. They could have quiet exhausts and still race. If the mfgs were restricted to X amount of db's, they would just build exhausts to meet that rule and they would still race each other. They race electric bikes which don't have any exhaust noise.

I'm with you on the noise. I have had exhaust systems on my cars in the past, but NOTHING like what they are doing today with what seems like 6,000,000 DB noise levels. My cars had a good sound, not ear shattering and wake the dead type of sound.

My big issue here is they want to stop any and all modification of ANY production vehicle if it came with a VIN. This will KILL all grass roots racing of any type of motorsport because most people don't have the money or the skills to make a vehicle from scratch to go race.

Electric vehicles are cool and definitely have a place in the future, BUT... The EPA should not have the power to unilaterally mandate that people can't modify vehicles for race only use.

I also think that CA has gone too far with not allowing any modification to exhaust systems starting with vehicles manufactured from1-1-2013. So long as the DB level is legal, it shouldn't be an issue, but if it didn't come from the factory, it's not legal in this state.

If you can't tell, this is a sore spot with me. 99% of the cars produced will never be modified, but for those that are there should be SENSIBLE laws (not regulations) governing what modifications can be done. And this should be on a federal level, not state by state so as to reduce any confusion and so that manufacturers and consumers can easily understand what is legal and what isn't. Right now the rules, regulations and laws can confuse members of Mensa.
