that is why the warranty should not be voided unless the accessory is the culprit. I was a service manager for yamaha, suzuki, ktm, and kawasaki for many years. The warranty reps had the final say in all warranty repairs no matter what. THey never voided any warranty b/c of aftermart add ons, cams, exhaust, big bore kits, etc etc, unless they were the cause of the problem needing warranty.
the punishment (warranty voided) should be in line with the crime committed
