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?
