Sorry Gowen!
Didn?t see your question.
I have milled the flywheel,but don?t remember how much.
I will post the answer later when I measured it.
You have to mill a new cone with the 125cc flywheel and you reduce the strenght by doing that.Calculate,and it maybe is "no problem".
It?s a winner for high rpm-racing.

Hmm. I am still considering trying the kx125 ignition. But, I did call about the PVL ignition and they only sell the entire ignition system which runs from them at $501. Not too bad, but here is what I'm worried about, I read that doordie has used special high RPM bearings? Should I think about that before changing the flywheel? I'm a bit worried! I wil try the KX deal and let you guys know, if it does not work, I will give PVL a shot. I will also check to see if one pops up on ebay or something like that!

Thanks

I'd like to know what a high rpm bearing is.  I bet its one with a looser fit.

I not sure your crank is trued/balanced,but if your going WFO a lot I'd suggest it.

Good eye Kawadude,how'd that ".if" get included?

[gowen]

Mike, the only wfo runs I do is in woods/trails so it is no more than wfo for more than 20 seconds at the most. Usally sprints from a to b fast. I ride mostly woods but occasionally drag strips which I run 5th wot for less than a minute at most. So, if still recommended, I will do that, but I hate to crack that case when I just had the bearings replaced..

Make sure that all top end is what you want if you get the PVL,because your 500 will scream more than a 125 with it!
