pocket bike pipe mod
Last night we modified my sons pocket bike pipe - had to reshape radius around the head - split the expansion chamber and moved the front cone foward. Added 2 1/2 inches to the center. This goes along with a bunch of other engine mods he did. Hope it works OK - the engine that is.
