01 cr80 noise!

Recommended Posts

Hi everyone, posting this up for my brother. Recently bought this 01 cr80 not running. Took the top end to find the cylinder and ring scored. The jug itself is in great condition so we just got a replacement. Put everything back together and starts good but makes this weird kind of rattling rubbing sound. Seems to be coming from the bottom end but can't pin point the spot exactly. Also the kick starter seems to get stuck every so often and the only way to free it is by turning it over with a ratchet on the flywheel side. We are going to pull the engine out and disassemble it to see what we can find. Any ideas on what it might be or what to look for would really be appreciated. Here's a video of it. It's a bit hard to here the noise but it's there.

worst cr80 iv seen. what is that base gasket?

Wow! Thanks for the great compliment. It's a legit cr80 with a minor issue that we are working on fixing. Does that justify it being the worst ever? The gasket is a temp while the new moose kit arrives. This one is the same thickness as the one we removed I believed it was .020in.
