Thanks for the help KDXGarage much appreciated

, has anyone got a definite picture of the power valve system in a 95-8 cylinder? The pictures i get from the riva motorsports site
Rivamotorsports.com's Kawasaki Dirt Bikes Parts Finder
dont really help that much. i can see the cylinder heads are different as in the coolant ports through the head but would that be a major issue? i have asked some local kawasaki dealers down here in Aus but no one can give me a definate answer.
also one other thing, what is the thread size of the left hand thread on the flywheel kx250 93? the tool i need is a 57001-252 but now being aftermarket it'd just be easier to tell them what thread it has.
