When I was 15 I bought a 71 R5-B that looked exactly like the one above. Man that bike was fast. I miss it and would love another one some day.
I finished boring the cases on the Z1 Kaw motor last night, all I need now to put the lower end together is the timing chain. I have a fancy 124 link one on its way , I have a big pin crank, and 32 tooth cam sprockets so it takes a little longer chain than stock. In the mean time, I could use some help pulling the rest of my engine parts off the shelf and organizing it all. It has been many, many years since I tore this girl down and I hope I didn't misplace anything. Somewhere in that mess is a Superbike Mike, titanium valved, ported and polished race head that has been finished and packed away for the last 15 years.
