My friend is renting a compression tester from autozone for his 40ex and while he has it I might as well test mine, does anyone know the compression psi range of a 250ex and also what the valve settings are suppost to be on?

the valve settings should be .006 on both sides, I THINK. I'm pretty sure, but not positive.

According to my honda manual for '06='07 it says 185psi with the starter only turning the engine... hope this helps

p.s. remember the compression should be tested with the engine at operating temp....
