I was just rereading the epa regs. on modifying vechicles for highway use. Seems that motorbikes are drawing their attention again. Seems scary that even a simple change of a sprocket or even different size tire could make you in violation of epa rules, not to mention all the motor mods we do. If they choose to inforce the already existing laws appartently we are subject to a 10,000 dollar per day fine.
