I'll do the easy one first...

14T/42T front and rear -- it's a great combination if you don't want to go too fast, but want to get there like a lunatic! Allegedly!! Very Happy

How does the bike start and idle. How does it ride out of the power? If you have the ignition on (engine not running) and disconnect the TPS, does the servo motor sweep to the "Hi" position? If you then plug the TPS back in, does it return to "LO"? This will at least verify the servo is doing it's job correctly.

Info on setting the RC Valves can be found in the Tuning Section. PLEASE do not ask what a TPS is etc., all the information is in the Tuning Section!!

You want to check all the easy stuff first. Carb settings/clean jets, clear fuel tank breather, clean and tight electrical connections. Is the bike stock? Always easier to work with a stock bike whenever possible, to eliminate incompatible modifications.

What happens in 1st, 2nd, and 3rd gears? Does the bike run well and rev cleanly?

I also suggest removing the exhausts and having a look up the exhaust ports for damaged/scored pistons. For the sake of a pair of base gaskets, I would remove the cylinders and have a look more closely at the bores. No need to remove the heads at this point, which will save you about £20.
