I have a press and was wondering if its possible to press out my cylinders, and then put new ones in myself without damaging them? ???

You've got to heat the cylinder to about 350 degrees F and support the cylinder well. Push from the bottom of the sleeve.

Yes but you will still have to rebore as they never go back in exactly the same

If you do manage to get set up to put the new sleeve in, here's an old trick.
Forget about 'fridges etc, get a steel bucket, some dry ice (party ice), some metho (not for drinking), and a thick set of rubber gloves.
Put the dry ice into the bucket & pour the metho over it (you need enough to cover the sleeve completely).
The bucket will instantly become icy cold & heaps of "smoke" will come from the mixture.
Put your sleeve into it & leave it for about two (2) minutes.
Take the sleeve out (even with gloves, use something like pliars to take it out - use your hands & you have no fingers-instantly!).
The sleeve will now drop straight into the bore.
I've used this on truck motors & it works well.
After about five hours, strain the mixture, mix with an antacid such as Sal-Vital and sip it slowly, it's called "bush champagne".
All bull#$%* aside, this works well and your wife won't go off at you for having bike parts in the fridge in the house.
