Will a KTM,KX, or other 2 stroke 65cc dirtbike exhuast fit on my motor? I was wondering because I figured they are both 65cc, so the ports might match? I know that those little bikes pack some power and the expansion chamber pipes are massive and those are the easiest way to modify two strokes.

With a lil welding and persistence the headers and mounts will be different but easy to fabricate bud!
