The Z1R's were actually uncrated at ATP (American Turbo Pak) in Santa Ana, Ca, Turbo installed along with the new TC side cover emblem, recrated and then shipped on. ATP was owned by Bill Hahn Sr. but he sold out not long after the RTC thing started. Bill was one sharp dude. As a teenager I used to hang around ATP. Even remember when Jr. was born. I had a 750 Honda with his kit and then did a Z1 around 1977. Compared to today they were slow but just like today they were damn near as fast as a Pro Stock was then and at the time the Pro Stock leader was Terry Vance / Byron Hines, both working for RC engineering (Russ Collins), in Gardeana, CA. Aah the good old days! God this seems like a lifetime ago!
That is one clean H2. Any chance it's for sale? That too was my first bike in Jan. 1972 and I'd like to find one just for fun.
