hey again,

i just debaffled my mufflers (just the end ones and nothing more) and i can say my bonne sounds more rude and i really like it. but i guess having debaffled it brought out some noises that maybe was silenced before.

while riding, i noticed what sounds like a sputtering or spitting noise coming out of the exhaust. noise most noticable when decelerating of letting off the throttle. not really sure if that can be called backfiring, but just wanted to know if it was normal or what could be causing that sound and how to get rid of it if it's bad.

thanks once again.

Most likely you have not yet removed your AI, this causes a good deal of "backfiring" type stuff on deceleration. Not sure if they check emissions regularely in CAN but if not yank that stuff and see if it is cured.

More than likely you are a lean. Back out 1 turn on your pilot screws.
