I'm trying to help someone resurrect an ancient (~1981) Kawi KLT200-A1 3-wheeler. I think at this point, the compression is gone. It has good spark, gets gas to the carb, but no joy after that. I tried ether, but it will only start to fire, and then nothing. Does anyone know of a source for a new piston/rings? I'm also looking for a muffler for it (used would be fine if it's in decent shape). Cost is an issue for this project.
