What do I need to look at for the root cause of this? The flywheel not being seated properly? Could the spacer on the stator being too large cause this? I have a different flywheel I could try, but that may not be the problem????

Is the keyways in the crank and flywheel undamaged? How about the key itself is it the right size and hardness too soft would be the worst thing but too hard might be a problem too? You could take some lapping compound and lap in the tapers until it is all a dull grey and that would mean that it has full contact all the way around.

The key came from a used crank that I ran for many races, that why I was thinking either flywheel or stator causing the issues.

35ftlbs with a torque wrench.Lapping is a good idea.There are different key styles used.One is a deeper slot and key matches it.

I used to have this problem all the time. It definitely takes the right key. But also I had one shear and I took the broken key out and put a new one in and reinstalled and had the flywheel crack at the steel hub believe it or not brand new flywheel too. Anyways there was the tiniest bit of key still in there some how and it offset the new one enough to cause it to shear again and crack the flywheel. Crazy. Definitely my fault but the half moon key came out and so did the other piece, never would have thought there would be fragments in there that I would have to scrape and pick at to get out...

DJ is talking about the IA ATV series which is suppose to be really good.
I used to race my local series, because it was so close to where I live. I haven't races for about 2 years, but I got the itch again. I went and watched last weekend's race, and it made me miss it even more.
