I have a PX200 with a Polini 208cc Kit. When checking my ignition timing with a timing light, its erratic. What I mean is, its sometimes on the "IT" mark and sometimes its a little of to the right of the IT mark. I don't think this is normal because my PX150 (Polini 177cc Kit) doesn't do this. Is there anything wrong with my ignition system? Any input will be greatly appreciated. Thanks.
Just out of interest, what was the problem?
The "primary coil" and "pick up" on the stator was defective.
Yeah i encountered that problem myself once, riding and whenever accelerating it would cut then pick up again. Until one day it cut when i was accelerating up a hill… Replaced the whole coil
