    i need the psi rating for a compression tester but ive noticed some oil at the bottom of the barrel so i recon the base gasket has gone. its running fine but wont go above 30 unless on the flat or down hill and wont go past 7k so new gasket set and might aswell give it a new set of rings while im at it since the piston and rings in it have done 15k

    Might aswell. They do wear out over time.

    yeh for a piston and ring kit its about £4 more than just 2 rings so might aswell get both and a new small end is only a few ££££ and then the gaskets to go with it all.
