Both sides crackle when i first let off the throttle, which i've heard is fine, but when im rolling the right side will still go "pop...pop...pop..." i adjusted the air/fuel mixture to make it a little richer and it did nothing. also, i tightened the muffler clamp in case any air was getting in, also not the problem.
