Old KZs are the bomb. I keep looking at 650s and will probably pick up another one someday. The damn things are bullet proof.
I've had several 650s from stock, touring, to full out superbikes, '84 and '85 GPz550s. Currently have an '81 GPz550 on the table being prepped for an AHRMA race.
Guess I need to scan some old photos............ when I do I'll post 'em up here.
By the way, I still have a front end and mag wheels off a '78 650 if anyone is interested.
The difference between genius and stupidity is genius has its limits....
