I got a 1983 Suzuki alt 125. Smoked bad when running.. So I rebuilt the carb, put new rings and new timing chain on it and it still smokes like crazy and takes a while to idle back down. Any ideas??

 

Seems to me just putting new rings on a worn piston isn't accomplishing much.Might be better off getting the next over size piston and rings and having it bored out.Plus a couple new valve guide seals wouldn't hurt either.1983 Suzuki ALT125 CRANKSHAFT | Cycle Parts Outlet
