So this more than likly has ben asked but here it is. My moped starts vibrate in pulses as it speeds up but it seems to speed up faster than usual is this something bad. I should say it did this awhile ago but now has stoped doing that. This is we're it turns bad when stoped and at idle taking off makes the engine want to die witch is from the cluch i would check it but don't have all the right tool anything else i should think about changing. Im thinking of changing anything cheap in the cluch im needing more speed well that give me more speed changing the springs
