I just picked up a bike from a friend and I think it's a 1980 RM50.
He says it occasionally starts and wanted to get it running for his son.
I pulled the carb and cleaned it, checked for spark and I got it, but I couldn't get it to run. I pulled the exhaust off and sludge just poured out. I then stuck my finger in the cylinder and it is filled with gunk.
I'm getting ready to pull the top end off, but I need some advice first. I've never torn down a 2-stroke before. Is there anything special I should know? I don't have a manual but think it should be fairly straight forward with this simple engine. Can I still get new gaskets for this old of a bike?
Thanks,
Josh
