I think I've finally found one of these, two questions.

What is one worth?
My manual shows the part # as 57001-112, the one I found is listed as 57001-112-1, is there a differnence?
This is for a 76 KZ900A4

Yes the best, good ol' screw clamps. Plus you take a air grinder with a smooth whatever and smooth out the insides of the clamp first. And I have 2 pieces of aluminum stock. appox. 1" x 2 12" long. I set the 2 pieces of aluminum across the block at the insides of 2 & 3 piston just at the point were all 4 pistons are straight across just to hold on the down stroke of 2 & 3. Hard to explain! But this way you drop cylinder over all 4 at same time. Just enough of a drop, so the rings make it in. take off clamps and pull the spacer blocks out and there you go.
I did get this once in a pile of parts I bought cheap. I got $200 for this one on ebay 1-2 yrs. ago.
I tripled my investment on this score May of 2014

Nice Kawi tool to have for nostalgic reasoning (hang on the wall ART Deco).

As for being a required tool for cylinder drop onto/over pistons, nope not needed. Never had a problem in several builds now.

Cool just the same if the price is right.
