cheers

Did you upjet the carb? Having a less restrictive exhaust and intake is all very well but unless you've upjetted your bike will now be running seriously lean.

With standard airbox and pit bike pipe it'll run okay. Mate of mine with a 90 using the same combination held it flat out only stopping for fuel, for 7 hours and it was fine.

Go one tooth down on the front sprocket. Count the teeth on the one you have already, I may have one you can have for the postage.
