G'day Terry
Here are some pics of the Kawasaki sleeves and the blocks that they came from.
The blocks were ID'd from the cam chain adjuster hole. (Square or rectangular)
I think that this might be a mix of "Z", "KZ" & "GPZ".
The lip thickness was a PITA for Honda blocks, but that can be dealt with.
All of the Kwaka sleeves are sealed under the top lip, which is a good idea, unlike the O Rings on the 750 Hondas.
That Loctite is as mean as cat #$%*.
Give or take a bit with these measurements mate.
Mick.
