If anyone can help me with this id be very happy because i really miss riding my gasbike. A while back my bike stopped running for no apparent reason, and after much troubleshooting, and replacing every last electrical part on the bike, it still wont run. -_- it gets full compression, and the carb is working fine. the only thing really wrong with it is that it is greasy and filthy, which makes me think it might be a grounding problem, if anyone has any input on that, or anything else that might help, as i said before, it would be greatly appreciated:-||

if you can hold the spark plug in your hand, your hand on a good motor ground and roll the bike without getting bit, your electrics still aren't working

If you're worried about dirt or oil interfering with grounding, then grab a can of wd40 and spray all grounding points thoroughly with it. No need to wipe it off or let it dry, wd40 doesn't interfere with electricity. If you spray and nothing happens, then that wasn't the problem. If you've got rubber or tape between your engine mounts, that could also be interfering with your ground.

You say you have compression but how much? Sometimes some compression is just not enough. Have you checked your mag rotor? I've seen rotors lose their magnetism. Is your rotor installed correctly if you removed it?

When you replaced your magneto did you notice any oil leakage? Could be your seal behind there. Just throwing my change in there.
