    the bike was running fine then just started back firing on me and popping loud and sometimes it will stop and just start going but other times it fires up then dies and pops two times and shuts off. If you can help me it would be appreciated had her running fine flying down the road then it started doing this i like working on her but i would rather enjoy riding her!

    The first thing that I look at with your description would be the woodruff key in the rotor.

    Make sure the rotor keyway and the crank keyway are lined up. (Key still in the right spot on both)

    If you bring the piston to TDC, and the rotor is as depicted as in the picture, you engine is in timed.
