Hi everyone, Tried to start my bike yesterday. I pulled the decompression lever in and kicked it over. Then I heard a clunking sound in the engine and the engine jammed to a stop and wouldn’t turn over anymore. I can turn it over in reverse 1 revolution then it clunks to a stop. It sounds to me like the valves or valve is hitting the piston. I pulled off the top cover cap to check parts. The camshaft, rockers, cam sprocket, etc. seem fine. With the cover off, I turned the engine over and it has compression. Also, the valves aren’t sticking. I don’t know much about this engine but I think it could be a problem with the decompressor system??? Anyone have any ideas????
