My 250 seems gutless in relation to others!!!:frown:
Its like the power valve takes ages to open, so not snappy as per my old rm!

It has full fmf system and the red power valve spring. I have checked the operation and the valve goes to the top of the exhaust port. i have just removed the barrell and the piston and rings look in good shape.( have a new piston which will go in)
Always has good plug and air filter cleaned every ride..
I has the twin mapping switch fitted and this is working correctly..

The powervalve operting rod seems a little stiff to me.... anyone had gried with this before??
