Get one of these:

Called a brush hone or flap hone.

Disagree with the gentleman above who stated do nothing. Smokers will develope a glazing on the cylinder walls. Even though you can still see the hone marks, new rings will seat much better and maintain compression longer if you deglaze the cylinder walls first. You only need to run the brush hone thru it for maybe 15-30secs to do this. You will not dimensionally alter the cylinder or damage the existing hone marks, nor will it damage the port edges. All it will do is deglaze the cylinder.

If you have small dainty hands, you can acheive the same thing with some soapy water and a scotchbrite pad. Just do a google search on deglazing a 2-stroke cylinder and you'll find plenty of info and alternatives.
A good bike mechanic only needs two tools, WD40 and duct tape. If it doesn't move, but should, use the WD40. If it does move but shouldn't use the duct tape.
