My bike never backfires, one day i was ridding to my friends house and i let off the gas and it was backfiring? *** then i sped up and did the same thing and it didnt backfire. It does this every once in a while. Could it be the hotstart cable like getting stuck or something? it starts on first to third kick every time.

Thanks!

Mine was doing the same thing. Just had it fixed. Main jet in mine was too big and the carburator needed adjusting. Doesn't do it anymore.

You probably need a carb cleaning.
