If they are used pistons and pins, you may need a pusher to get the pins back in the pistons. Use new spring clips for the pins.

Not sure I would try that one on a KZ engine. Done it on a car.bluezbike wrote: Someone a little while ago had suggested putting each piston into the block separately....... and then connecting the lot to the crank arms. Seems like it could work, not much room for fingers though

Install the base gasket and whatever o-rings, cam chain guides etc. you have there.
Rotate the crank until pistons 1 and 4 are all the way down and 2 and 3 are all the way up.
Insert wooden supports between the base gasket and pistons 2 and 3 (I made the supports pictured below in like 5 minutes) and rotate the crank until pistons 2 and 3 are resting against the supports and are as centered as possible.
Apply a thin coat of assembly lube or engine oil to the cylinder bores, slide the cylinder block onto the studs and insert the top of pistons 2 and 3 into their bores.
Compressing the rings with whatever you need (I've never used anything but my hands) gently slide/wiggle the block down over the rings - remember to space the ring gaps 120 degrees apart.
Once you have pistons 2 and 3 installed lift them off the supports by rotating the crank and remove the supports.
Rotate the crank so that 2 and 3 comes down and 1 and 4 comes up and repeat the above for pistons 1 and 4, there you go.
Edit: Btw, when installing the piston pin clips, DO NOT forget to stuff rags or whatever in the case holes around the rods, clips down the crank case is not a good thing. :whistle: :pinch:

The strips may be cut from an aluminum can.
Be extra careful with the oil rings, to have them properly fitted without overlap, and not damaged during the during the installation process.
Have never been fortunate enough to own the real McCoy:

That's how I do it.bluezbike wrote: Someone a little while ago had suggested putting each piston into the block separately....... and then connecting the lot to the crank arms. Seems like it could work, not much room for fingers though
Insert each piston into it's cylinder, lower the block onto the connecting rods, insert wrist pins and retainer clips.
Do the pair in the middle first, then rotate the crank to bring up the outer pair.
Yes, it's tricky, but it works.
