My buddys got a 125 that seems to run fine sometimes, but i rode it the other day and when im at full throttle high RPMS it does like a spudder, it almost seems like a fuel cut off like a rev limited in a car but then it goes again. Its not at over rev either ide say about 3/4th of the way revved up. Its def. running rich i have no idea if that could be the problem or what, we just changed the top end (which it was doing this before that). Any ideas?
