backfiring?
I just reshimed my crf450 with the shim kit. And now it will backfire, but won't start. This was my first solo time shimming the bike
It sounds like you don't have enough clearence, re measure your clearence and make sure you keep the shims that you take out seperated so can measure them to get the right clearence.
