    What size piston rings does an 80cc chinese motor have? I ran to lean cause I had a cracked intake manifold and didn't know it. I ended up loosing the temper out of my rings cause it got to hot. It only has 65psi compression right now.lol but it'll run, just has no power.

    more info is needed to answer that one...for example, the ring on the left is from a "70cc" sold as such...the ring on the right came out of an engine listed as an "80cc"...unless you're able to get rings from the same source as your "80" i'd suggest measuring your parts to get the best answer:
