Per FSM for '77~'79 KZ1000:

Single front disc, standard 6.9~7.1 mm, with 6 mm service limit;

Good Fortune!

Yip, 4.5mm min stamped on them, one is 4.65mm & the other 4.52mm.

Just thinking of getting the original single disc on the 750 B2 taken down to 5mm & doing the same to the original single disc on the 650 B1. I'll not be using either otherwise & they're worth more to me when turned down than selling, they'd be sitting gathering dust if i dont get them machined.
