Hey all I have a 1980 honda cb125s, and my bike has almost no horsepower now. it was running fine, until my throttle cable broke. I changed that, and hadn't put the part that goes in the carb right so it was open, and it just revved really hard. I fixed my error, but now I have almost no power and the bike dies, almost like its flooding. Is this a cam chain issue? there is a racket coming from where the tensioner is (sounds like a lot of BBs rolling around). I don't know much about motorcycles, I am learning on this bike. I appreciate any responses.
