Chaos......got an airbox scheme I'm working on, got to work around the air meter, and don't want to go out the rear, like Brutus (sp) did up in Alaska. That'll be Gen 2 with an alternative exhaust.
Gryph.......it ain't a damn moped-powered Honda like you used to pick up and put in your trunk. The motor alone weighs about 350 lbs. Good thing I hid a lithium and ditched the 100lb. battery. The real secret was drilling out all the solid tubes in the frame. Lots of guys don't know you can run hollow tube frames ( old racers trick).
Laitch...good eye....they are indeed Shinko 705's in dual sport tread, 120x80 front, 140x80 rear. The constraint on the rear is not clearance, as you know it's wheel width. And I have been working on a suitable alternative other than a three spoke. The bike was designed for Forest Service roads, mainly sandy. Debated full knobs which I have used before, but the duals are more versatile for paved transition sections.
Since it had been sitting 5+ years, the fuel pump system, brake master cylinders, calipers, lines,splines, fluids all had to be done.
By stubbornly removing all handle bar controls I created some interesting wiring and starter challenges, saving about 20 lbs. of wiring from stripping out OEM and running new circuits. The lithium battery in the relay box was a challenge. The tank was a solid 18 hours of wet-dry, AFTER using a chemical remover for the original white paint. Debating leaving that heavy center stand on there, and have some tweak's and polishing to do, but it's running good! I am grinnin'! :riding:
