hi i got the above mentioned bike,this morning i had it running and then it stopped. i got no fire to my plug,i tried 2 or 3 others and no spark,before it quit it seemed to be missing when you tried to rev it up but only after you let it warm up.while it was warming up you could rev it up and it worked fine.any suggestions?

 

Try getting a new plug,sometime used plugs dont fire,they don't in my quad.What gets me is the plug will foul in my quad but fire in my weed wacker.did a kill swich get hit and maybe you didn't catch it.check all the ground wires,hopefully the coil didn't puke on ya.
