Darn, i don't think that'll work. I have a 1000, so I need the 72mm one.

The problem is as soon as you go bigger 1075, 1105 etc or 700cc or 810 on mine they don't work either..... I was seriously thinking about one too till I read and figured out that.

OK... my factory Z1 900 ring compression tool did not work well on my 1015cc pistons and it didn't work AT ALL on my 1075cc pistons.
So I sold it, the piston stabilizing rods and the big orange bag/case.

I have shown pictures of this problem before even trying it on the engine....here on the KZR site and those photos can be found if looking around.

However, my factory KZ1000 ring compressor worked flawlessly, and even with my 1075cc over size pistons!!
The damn cylinder block just slid down over the four, 2mm over sized pistons and rings so fast, it actually caught me off guard.
So fast, I couldn't slow it down in time to watch what was happening...the sleeves just slipped right down and banged into the compression tool in one smooth motion.
No damage or anything,
I just wasn't really ready for it to go together that fast.
With the tool removed, (EASY) the block pushed right down with little effort and bottomed out into the locating dowel pins.....
Plus, taking the tool apart after this is just a joy, so satisfying.... compared to trying to do it with all the nutty contraptions, hose clamps, beer cans, plastic wire ties (you name it) I've seen them all.
The entire procedure took 4 minutes after squeezing the rings and that included removing the tool from the case and studs.

Sounds great. I always dread putting the barrels back on. PITA I don't do it enough to warrant buying one though. Just curious, what do they cost now?

First attempt, and was a joy too. A cheap one...







The black plastic strip is slick. It gets pressed down the piston by the bottom of the cylinder sleeve as it presses on the edge of the strip. The rings pop free inside the sleeve where they should, with the gaps locked in their proper positions. You don't get that using fingers to compress the rings.

What is the plastic? What's it from/for?

No doubt the tool is better, but I haven't had trouble with generous assembly lube and fingers to fit rings back in the cylinders. My hands are not to big or fat to reach though. I would not use a home made contraption. R

Sorry for the late response to the question about my home-made plastic strip-backed hose clamp contraption.

1" wide x 1/16" thick LDPE soft plastic strips were used behind the hose clamps primarily to lock the rings in the FSM specified orientation to the pistons. With the clamps adjusted properly, the soft/slick plastic allows the cylinder sleeve edge to gently push the strip (and clamp) down the piston, releasing each ring within the cylinder as it passes in the exact-same position it was clamped...with assurance that no scratches were left behind on the piston.
Once the four clamped strips were properly placed on the pistons, the cylinder installation process was slickity-split fast...and precise.

Where did you get it? Do you have any you'd be willing to sell me? I am getting ready to put pistons in my cylinders and could really use some of this.

Came from a plastics supplier for a project. Had to buy a minimum quantity to get the stuff.

I'll send you a PM

Thank you

Do you have any idea what engine this part number 57001-531 fits?I bought it from an Ebay seller in Louisiana.Was supposed to fit KZ1000.It doesnt.Have no idea what it fits but it wont work on a Z1.

Evidently for a 650.

Z1 and KZ1000 are also different. I've been looking for a Z1 ring compressor for a few months with no success so far. I have one in my shop right now but it belongs to a buddy.
