I am trying to determine what the problem is and I know there is someone who has way more brains than I do. The problem is I can't keep it running at slow RPMS and it misses and back fired thru the carb. I can't see see the timing mark in the site glass when trying to set timing is the problem. I have removed the front cylinder spark plug, rotated the wheel till the piston was at TDC, looked in the timing inspection hole and the lil round mark is right where it is suppose to be. Put the plug back in, inserted the glass inspection plug in the hole, started engine and there is no mark. I rotated the sensor plate in both directions and still no mark. OH ya I forgot, the bike is a '94 bagger and I just replaced the stator. But that is another issue. It ran fine till I replaced the stator and I realize the stator replacement should not have any effect on the timing, well I think. Any ideas would be greatly appreciate.
