I like it too. He should post up more pictures if he's lookin to get his BIN price. I have a green project, makes me want to work on it. But I'm kinda lazy. LOL
God that thing is awesome. Factory fuel-injected monkey with 10 miles. What a beautiful little bike. The dash, side panels, wheels, everything on this thing is so legit.
The 4 speeds are all K0's and K1's. They started making them in June of 1970, and continued thru 72 and I think into 1973. But I'm not sure about the 73.------EDIT---- On second thought I think the K2's began sometime in 72. No 73 4 speed bikes. Someone here will know.
