Compression and piston rings
Posted: Mon Feb 06, 2023 6:28 pm
Any aftermarket source for standard sized piston rings (e.g. Wiseco, etc.)? Any other bikes that use the same pistons?
Not sure I need them, but before I dig into the engine, I want to know what I'm up against dollar-wise.
More detailed background for those interested:
Got a 92 from my buddy who gave up on it. Been sitting at least a year. changed the oil, cleaned the carbs. Saturday, got it to start and run a bit on 1/2 choke so there is hope. Today I ran a dry compression test. All cylinders were right around 90 psi. Wet test bumped it up to about 120 for each cylinder. I'm not going to freak out yet. I will give the carbs another cleaning and double check all ports and passages are clear. Then I will see if I can get it running and get the existing rings to seal up a bit better.
Thanks
Mike
