Skip's old x40, (tiny wheeled free-spirit) his rear micro wheel broke and we used the front on the nightmurray. that motor went to his maxi and this went to the wayside. Trade Soft Intentions (my solex) for it and built it back up with some old e50 cases, a55 topend, BACKWARDS bing hose-clamped to the intake. stock gutted pipe, and some sandblasted 5 stars. The knobbies were around and the original small wheels were pretty wide so it even fit 3's It's still needing a bit of work but kinda rad. fenders coming back later, better tuning needed, new sealed wheel bearings, and for damnsure a pipe.
