What compression on your 500?
I_Duddits:
I know my engine needs a rebuild but I'm running it while I rebuild my spare.
So on the bench (it's difficult to get a good kick on the starter) I get about 115psi. Is this going to be enough to start the beast? I reckon all assembled, when I can get a good purchase on the kick starter and kick it like I stole it, I should get a 135'ish out of it.
So is 115 to 135 gonna be enough?
How much is yours? I'm trying to get a feel for the average.

No throttle on the bike as yet, why would it make a difference to the reading?

yes it will make a difference and 135psi is low even for a 125.
