So, I do a ton of scooter work. I’m also a certified auto tech and after working on hundreds of scooters I have one now that I can’t figure out. Motor runs rough, won’t pull any rpm’s. Started diagnosing it in the chassis. Verified it wasnt a fuel issue, (it didn’t want more or less fuel. Verified compression and camVerified exhaust wasn’t plugged. Checked valve lash. So.. I have a stand alone test station with all the electronics so I can run it on the bench.. no change. I’ve ran different stators on it.. I know that just supply’s ac to the cdi box and I’m getting proper voltage.. verified TDC on the piston and marks line up in the proper spot on the flywheel. The only thing I see that’s odd is the ignition timing checked with a timing light seems way off. Pick up coil is in the right spot. At TDC (verified mechanically) the flywheel is on its mark. Yes I tried different cdi boxes. So tell me wth is going on?
