If you are just scratching it up to install new pistons/rings, then it is pretty easy. If you are boring it, then I'd take it to a shop. To hone it, get a good cylinder hone and some honing oil. insert the hone in the cylinder and spin it while moving it up and down on the cylinder. Look for a nice "cross-hatch" pattern in the cylinder walls. You may need to champfer the ports of they feel sharp. I usually take a small piece of snadpaper and take the edge off the ports. This keeps the rings from popping. Wash with warm soapy water, dry, and I usually put a thin coat of injector oil to heep her fresh until reassembly.
