I was just looking at sandcast parts, a good percentage are not from a sandcast, but others are so badly damaged it's hard to believe. The one lower 1/2 crankcase has the entire end broken off. Of course some welding will be required for only $499. I guess if it has value but is bashed beyond recognition it's still worth 80% of new. The 16" tire on a 4 hole hub is somehow sandcast. The headlight ear with the hole ripped off where the turn signal mounts, The airbox in 27 pieces is only what a repro costs.
I'm going to list an engine soon and will try to do better but they leave me a lot of room. The one there now has no good crankcase covers, 10 bolt clutch cover, the chain went into the case, fins broken from the head and cylinder, engine mount boss partly broken off, oil filter chrome and chipped, case hole on top of trans cover, the valve cover could be correct though. it was up to 2550, didn't sell and is now buy it now at 2200. I'd buy it for parts but geez, there's hardly anything I can use without major repairs. I'd be a player for 5-6 hundred to get the top end to do fin repair and take a shot at repairing the case.
