Backfiring from Bad Exhaust?

Hi everyone,

I am running a puch magnum mark II with 70cc tccd kit and 15mm bing and bullet pipe.

Recently, whenver I top out my speed, around 30-35, the exhaust starts to "pop" and "sputter", causing me to slow down, and making me go slower for some time.

Is this from a bad, clogged exhaust? Or something else? Any seasoned mopeders know what my problem is?

sounds like your rotor has slipped. reset it on the keyway, and you will be blasting much faster.

ive done this twice so far :(

Re: Backfiring from Bad Exhaust?

hes prolly right, backfiring is almost always caused by a cloggedexhaust or bad timing. but if you arent backfiring when you try to start it its not the exhaust

Re: Backfiring from Bad Exhaust?

its either the timing, or you have burned a hole in your piston.

What do you mean by "reseting it on the keyway?" Where or how do I do this? Sorry for any ignorance, I just don't really understand. Never encountered before.
