Thanks man. If it wasn't raining I'd give that a try right now. I'll do it tomorrow hopefully when the weather let's up. But I also tried to see if the powervalve was working by leaving the bike in neutral and giving it some good revs, I didn't see any movement inside... could this add to the problem of it being rich?
I don't think so but I honestly don't know.
If the PV is stuck open (it's supposed to closed at higher RPM) it will hurt your performance on the top end.
