Use cylinder liners?

Have a ca95 that hasn't run for 25 years. If I remember correctly it was smoking a quite a bit. Thinking that it needs reboring but I see that cylinder liners can be bought for this motor.
Am looking for advice on boring or liners as to which way to go.
The motor is free and the transmission should be good.

It's probably cheaper to have the cylinder bored. Check the top of the pistons in the engine. Look closely and you may see no number stamped on the top of the piston (std.) then if you see the number .25 (it's oversize 1) If you see .50 (it's oversize 2) .75 (oversize 3) & 1.0 (oversize 4)

Usually you can bore one to two sizes larger depending on the cylinder condition. If the cylinder is already bored to 1.0 over and the cylinder is bad, then you can have the cylinder re-sleeved and then bored to standard size piston once again. Both the re-sleeve and bore is usually done by a machine shop.

Yep any old machine shop and take care of the cylinders. It's pretty basic but you just need the right machines and a good eye for measurements.

Yup, I posted in the wrong spot first.........slow at learning how to use sites.
Thanks for the info.

No sweat. I have read in Honda service manuals that they recommend resurfacing the cylinders/ boring/ honing as the tolerances slip during the engines life. Doing anything else is last resort to me. I would probably find another cylinder before going through the hassle of using a liner or anything else.
