Well, due to the generosity of a number of you guys out there: the HS#1 engine is coming out of the frame in the next couple of days. It's time to start the "teardown chapter" for the Book. I have the gaskets, scored a nominal seat on eBay (probably will need a new cover), 2 K1 tanks from the boneyard (real cheap: they must have been suffering from the extended snows we're having here). You've sent me rebuildable headlight and mounting stuff, and I scrounged some guy's wiring harness from a bike he disassembled long ago.
Here we go, keep an eye out for pictures!
