Hi Andy

Thanks for all the advice I will try spraying the cleaner by the flywheel and see what happens. The bike sounds great and runs well at idle, the rpm is fine. the gearbox oil could explain the white smoke as its not too much air something is burning off.

I have an infrared heat gun that's how I know its hot. The top left barrel just at the start of the exhaust reaches about 90 degrees after a few minutes running where as the lower one reaches 130 degrees. They don't get much hotter after riding.

also I have striped and cleaned the power valve on the lower barrel it may have seized and the wires were full of gunk these have all been freed up now but haven't had chance to refit back due to young kids. So will be interesting to see what happens after that.

To be honest though I am expecting the worst. Any ideas what a crank rebuild will cost at GT's in Plymouth?

Ian
