Compression reading

[Philly Eddie]

What is a healthy ballpark range of psi for cylinder compression on a stock 450 (spring head)? I cannot find this info in any manual. Thanks.

This data is not usually stated for a single cylinder engine, because it isn't very useful I think.
With a multi cylinder engine, comparative readings between cylinders can be meaningful.

In the good old days, good compression was determined by being able to stand on the kickstarter for a few seconds.

I know my compression is good.Attempt a bump start in first or 2nd and the back wheel locks up and you stop .

Doesn't seem to have much effect with my Vento, Colin. Just me left standing on one leg, 18" or so off the ground ...

Craig, that reminds me of my mate's Norton Commando, which would leave you suspended in air; a bike for Real Men!
