just from my experiance. when i got my shee the guys said there was no spark. and when i got it home he was right no spark. so i replaced the flywheel oneday no spark, stator the next no spark, and coil and still no spark. so i thought it was the cdi. so i picked one up and still no spark. well after a few phone calls from the guys on this forum and tested everything and tried everything. well one day again i was on the phone with aguy off here on the forum and he asked me if i had still had teh key switch attached and i said no. well the 2 wires that connect to the switch were seperated once i connected them bam the bitch started up with him on the phone its like hot wireing a car. so my question is have you checked everything make sure your clearances are good on the stator to the flywheel. the plug boots are sometimes an issue as well. do you still have your key switch. also what about tors that will cause a no spark issue as well. others will chime in as well i am sure. sorry for the long drawn out post. good luck and let us know what you find.
