Back in the day I bought a new 1970 K0 (after my '70 Sporster was stolen). It was a spectacular, revolutionary bike! After putting 56k miles on it I built it into a trike, which was so terrifying I sold it immediately. I had bought a '71 K1 in the mean time that I rode for 35k miles. Later I went on to various Harleys, a BMW R100T and a Norton 750 Commando. Now I have '65 Triumph Bonneville I've rebuilt and a K1 I bought this fall; it hasn't run in decades. It turns over with the kick and electric starter. I'm working my way through the usual problems: rusty handlebars replaced and rewired, various bad electrical connections needing cleaning and dielectric grease, an ignition problem, rust in the gas tank, a little gunk in the carburetors, etc.
I also have 10 cars ranging from a 1936 Cord 810 Phaeton to a 2005 Jaguar XKR Convertible. My Daily driver is a Tesla Model 3.
I'm building a new shop in El Cajon which will be much easier to get to. When it's done I'll post an invitation to come see it.
