"Cam shafts from a 1983 KZ/GPZ1100. Engine # KZT10BE021376. Light varnish on journals, otherwise nice damage free condition."
What do you think about the condition of these cams, do they look ok by the photos?

New stem seals, and look at the valves and seats, guides, etc. Check it all, make sure its all good.
Watch out for the manual to give you the wrong torque spec for the cam caps. be careful torquing them down with the extra spring pressure. I apply pressure down on the cam, then fit the caps, relieving the added stress on the bolt hole threads.

Kawasaki didn't even rejet it for the Kerker pipe.
Yours will respond really well to the extra displacement and compression & cam.

I have one of these (bone stock ZN1100 B1 LTD) not quite as nice though , AND a set of 84 ZX1100 GPZ camshafts for it...
Am planning to use the valve springs and SOT buckets that came with the ZN1100 B1 LTD head (with 9,000 miles), or use the springs installed in my KZ1100-J head brand new in 2012, which have about 15,000 miles on them now. :whistle:
While researching part diagrams, I discovered the ZX1100 GPZ came with SOB buckets, and different springs (for that reason I assume). Further reading here supports using the SOT setup with the "Baby" GPZ profile, but not when going with high performance aftermarket cams.
So, I should be OK with the springs...right?

The GPz used different springs and also different retainers. While they were SOB retainers, they are not the same as the 650/750 retainers. The GPz Retainers sit up higher on the valves. That in turn yields more spring travel but less seat pressure if used with a particular spring, compared one to the other. Been a while since I measured it but as I recall it was at least .050" and I believe .100" taller installed height. I have notes somewhere. I might have it on my site under kzdata.html ......Can't remember...
You should be fine with the J SOT retainers and springs as long as the springs are still good. Shim to 90 - 100lbs on the seat and if you need more than a .015 shim to get that you should play it safe and check your coil bind clearance just because it's the right thing to do.....and you can't blame me if you have an issue... :woohoo:
