About time I registered as Ive often found your site informative and enjoyable.
Ok, I know my bike isn't strictly a KZ but a ZR but I hope you will make allowances for that.
The bike in question is a '91 ZR750 Zephyr. Ive had it for just over 3 years now and done a few mods on it in that time.
Most notably:-
GPz 750 cams in a ported head.
Six speed gearbox conversion out of a GPz 550.
Six pot calipers off a ZX7R
The gearbox job was a worthwhile one and I see some members have done the same on their KZ's:)
Jobs to do are to fit some bigger carbs and pods in place of the near stock setup. Otherwise its get out and ride time.:laugh:
