Red hot muffler
 

Hell guys I got a ssr 125tr today I started it up let run for about five min and right by the motor the pipe got red hot. HELP pls

Start with adjusting the valves. An exhaust valve that is not closing fully will cause this sort of problem. Most of these chinese engines come from the factory with tight valves and need to be adjusted.

Do that, run it again, and see if the problem persists. If so, check back in.

Thank u very munch megadan its my first pit bike and dont wont to start on the wrong foot and I will be adjusting the valves in the morning
