Sleeving is when you have the cylinder sleeves replaced with either new stock ones or aftermarket ones. I't's only required when you damage your sleeves beyond repair (by boring and honing).
Honing removes a lot less material and leaves a cross hatch design in the cylinders to help the reings seat.

I recently had my block sleeved (aftermarket) by golden eagle. When I got it back I took it down (along with my pistons) to my local machine shop and had them bore the sleeves (enlarge them close to the diameter you need) to about .002 pistons to wall clearance, then they honed it the rest of the way (to about .003 final piston to wall clearance)...

A bore and hone runs about $130 while a sleeving job runs about $749 for all 4 sleeves.

thanks that helped alot, so if i just leave the stock sleeves in there do i have to worry about reboring n sleeving for that ring to wall clearance if i am replacing the pistons wit CTR pistons(standard 81mm),or should the rings seal properly with just an honing job??

All you need is a standard honing job to seal the rings properly.

Unless your cylinder walls are scratched up or something, in which case you will need to overbore and then hone. However, you still won't need new sleeves unless the old sleeves are totally trashed.

as long as your cylinders are in good shape (no groves, out of round,etc) a simple honing job will do.
