Hi,
I recently installed a powervalve 265cc cylinder on my 1988 250R.
Can you check the compression on them like standard cylinders?
Will I need to go up a jet size if I had a stock ported 30 over cylinder on there before?

im in mesa az and run the 265 pv with some extra porting and polishing, ive got a 36 pwk carb, i mix av and racing fuel together and run yamalube 32:1, and i think im at like a 170 main, could be 172 but i know its one of those two.

250r4life,
What size of dome are you using? Do you know how to compression check a powervalve?
Thanks

to tell you the truth i dont know which dome i am using, but i have like 210+ psi. check the powervavle itself, or the whole powervalve cylinder? the cylinder is just like any other one, throw the tester in spark plug place and kick like crazy...
