Also, is there any tips anybody can give to make this job easier? I have been told to line the cylinders, and outside of pistons with ATF so they slide in easier, and also ATF will burn away very rapidly after engine is started.

Very importyant. Make sure the oil ring expander is not overlapped on the ends. It can jump while being installed. Observe each one as it goes into the bore ( it can't jump once inside).
If you install it with the expander ends overlapped, you will have one hole that oils and smokes like mad, and the cylinder will have to come back off.

I am about to do my 750 twin. I never though of trying to shove the pots into the cylinder and then lower the whole thing onto the rods......
The factory manual says assemble the pistons, put supports under them, apply ring clamps and lower the cylinder onto the pots.

I bought the ones from JC Whitney. About $32 each, seem to be very good quality.all the above sounds right, there are a lot of ways, ring compressors make it a lot easier,

If the block has a generous chamfer at the bottom of the sleeves, it makes the job a ton easier.
I ALWAYS soap and hot water scrub the bores with a bottle brush, then rinse them completely. They'll probably start to rust as soon as they dry. DON"T WORRY.
Use paper towels with clean engine oil [non synthetic] and wipe the bores out. Coat them good with oil to start with, then use as many towels as it takes to wipe the bores out until the towel stops turning black. When you reach that point, the bores are clean of debris and ready for a very light coat of oil to assemble. Use pressure when you wipe them...you'll see the towels turn black.
After the block is installed, turn the motor over and again, wipe out any excess oil in the bores.
And pay close attention to what Jay said about the oil expander ring....
I agree with the wooden popcicle stick method...handy little devils.

Somebody mentioned large hose clamps can be used as cheap ring compressors........
That's what I used,and it worked like a charm.(might have been Me that posted that)
Start off with 2 and 3 first.Plastic,springloaded clamps work well to help hold the block level while You're lowering in onto the pistons.Put the clamps on the studs to assist You...it works.
WiredGeorge(or someone here) posted some pics of the setup a while back.
And like mentioned...go slow,and don't expect it to happen with one visit...take a break from it and do it right,because You really DON'T want to have to pull it apart again(like mentioned).
Good luck with that.
