650 o ring question
Posted: Fri Jul 22, 2011 8:32 pm
I have a few 650 motors in bits. Some of them had/have 2 rubber o rings that are on the rh two inner cylinder studs. They are slid right down to the bottom of the stud, flush with the gasket surface of the top of the crankcase where the barrels seal.
My factory workshop manual does not mention them and none of the vesrah gasket kits I have used before on my running engine (which did not have them) have them in the kit.
Anyone ever encountered them and how do you know if you need them?
