Well in in the process of buying a new exhaust sytem (probly a fmf gnarly pipe with silencer) but i dont have the money yet. so for now i have the all stock exhaust. but i wanted to know if i took off the spark arrestor/silencer and just left the expansion chamber on, would that do any damage to my bike?
btw i have a 2001 kdx 200.. any advice would be appriciated
yes it would do damage you make any change to the exaust or air breather you MUST REJET THE CARBS look for forums that talk about what jetting you need for those modifications
if you increase the air flow out of the engine you must increase the card jetting to allow for more fuel more fuel more air or viseversa
