Kawasaki ZX/ZRX head gasket conundrum

(1/1)

Chrome Megaphone:
Help I hope Steve reads this.
I'm diving into another project, a 1989 ZX10, and have 3 ebay ZX11 pistons left over from my ZG1000 2mm overbore and so may as well go with a 76 mm bore with this.

I have a ZX10 head on the way but no cylinder block yet. 

Question:  is the 88-90 ZX10 head surface identical to the ZX11/ZRX1100?  I've been going cross-eyed looking at images on the web.  If I can drop the ZX10 head on a ZX/ZRX1100 block that'll save the cost and wait on my machinist.  Took three months to get my parts back.  It was worth the wait b/c he's the best around but this bike will be more of a plaything than the Connie.

One more question, searches for cases show the ZX10 and Concours cross over.  I suppose all I would need for a salvage yard Connie engine bottom end to work is the chain drive accessories and transmission?

Chrome Megaphone:
Went ahead and ordered a cheap gasket set for  ZX11.

I've been looking at notes on a 1052 build.
I think:
1 way is; (1989) ZX-10B Rods & ZRX-1100 pistons. (Stock cylinder height)
The other is; ZG rods, and ZX-11 pistons. (Cylinders must be decked?)

You can't combine the ZX-10B Rods and ZX-11 pistons on a Connie....
I was told that ZX-10B Rods and ZX-11 piston combination is too tall to fit into a ZG Cylinder.
Clearly there is a difference in piston height/wrist pin location.

So, I'm wondering if your planned ZX-10B Rod / ZX-11 Piston combination may be too tall for your ZX-10B Cylinder?

Ride safe, Ted
