Well got the flywheel off and sure enough the wires on the stator are all exposed. When I took the flywheel off we noticed a crack on the flywheel. Its not like a big crack or anything but more like a hairline crack that you can see from both sides. Is this something to worry about?? Also I put electrical tape around the new stator where it rubbed through on the other one. Anything else I should do to make it last longer? Thanks,
Justin

You should check the crank for up/down play and in-out movement.
Did somebody do a recent motor job to it?
You had better think of replacing the flywheel, and finding out why the clearance is not adequate to the stator. Electrical tape will be gone in an instant, and you'll be buying another stator, unless you check everything out thoroughly.

If it's a stock motor, I would do a complete rebuild, since your crankplate is likely loosening up in there, or the bearings are going out, and causing the crank to drift sideways.

Dremeling to the the inside of the flywheel can provide clearance, but it is certainly not a cure. If the stator is rubbing at all, even on the SEM emboss portion, then it's a symptom of a worse problem you need to determine.

Let me clarify for Justin.

The stator itself is fine. It is just the lead wires exiting the case that shorted out. there is no rubbing of the stator and flywheel.

The motor is a fairly fresh rebuild with 2mm Falicon.

The flywheel does have a hairline crack starting at the steel hub and extending outward, stopping about 1/2" from the outer edge.

Is there anything other than wrapping the lead wires with electrical tape one can do to keep them from wearing on the case and shorting out?

OK no big problem, but don't use that flywheel!, as it is ready to crack open soon or give an ugly spin out, which could destroy the stator. I can offer you a flywheel for cheap nowadays, or call for options.

Electrical tape is too soft to guard against that metal clip. I have the CDale wraparound fabric thingie cheapo, or you can use something tougher than tape. I also include a better clip bolt and locking cam, to ditch that lousy stock bolt that tends to seize,.... and is awkward to fumble with, and tends to round out.
