vinny, there's still a lot of bike there to work with if you're just going for a rider even with an engine swap wouldn't be a huge deal. That's a bike you can fix in spells as you pick up parts. You said the flywheel end of the crank is missing? Show pics of the mag side of the engine, that's got to be something to see. Good fortune.
I'll trade you some ammo for it.... I have a box of airsoft BBs, and a few left over lead pellets from my Beeman. May have 3 twinnyToo shells left over from my last squirrel hunt.
Nice one on Ebay right now. $100. Go ahead and get it before I spend my ammo money on it.
