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?

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...
