Was about to put the top end back on my KX250 today but noticed the cylinder is pretty badly glazed. There are zero cross hatch marks.
Reading conflicting stories on whether to diamond hone (using a diamond hone specifically made for plated two stroke cylinders), OR to just use scotch brite. I don't see how scotch bright will put cross hairs in a very hard plated cylinder wall.
Some people say they don't touch a glazed cylinder at all (which seems like a bad idea too).
What's the scoop?

Hate mailing parts off but it's either that or drop $600 for a new cylinder (and keep this one as a spare)
This cylinder sounds worn down, but normally, I would try a pair of nitrile gloves, some green Scotch Brite and some light, clear oil. Follow that up with some warm, soapy water and an old toothbrush. Keep hitting it with the often mentioned white rag cleanliness test. After that, hit it with the hair dryer and a light coat of oil.
