So I noticed my muffler falling off yesterday as I was riding the bike around town. This morning I decided to tighten the muffler back on to the bolts mounted out of the motor. All of a sudden the Bolt snapped. What do I do? Can these bolts be taken out of the motor and replaced? Would a pair of vice grips and a pair of engine mounting studs from dax do the trick? Has anyone had this happen to them?
