hi, i just bought my little brother a banshee, it runs fine at idle, but will backfire every once in a while, and has no top end power, it will rev up, but not the way it should, i belive it is electrical because i switched plug wires and now it seems to be doing it in the other cylinder, i pulled the stator cover and the whole timing plate was loose, i tightened it up and set the gap on the pickup to .020, the pickup does look like it was hit by the flywheel a few times, but it does still run, the woodruff key is good, i am kind of thinking it is the pickup or the coil, can you pros tell me what you think and how to check the electical parts,, thanks in advance
