The rings (and piston) ride on a film of oil, not metal. That's why the oil is there. If there was metal to metal contact it would wear out very quickly. With out the hatching, to retain oil, your engine will not last as long.Originally posted by motometal
...but the rings are now riding on peaks of metal (which will protrude thru said oil film) unstead of a nice smooth "bearing" type surface...
Very true.Originally posted by motometal
…My point? I think machining and quality control practices have produced engines that require minimal ring seating. Certainly, there are engines out there on the loose end of the tolerance that would require more break in and seating, thus furthering the need for careful break in and good cross hatch on the cylinder.. .
I’m sure it does to some extent but we’re not talking about deep scratches that hold a ton of oil.Regarding the finish on chrome fork tubes...if these imperfections or scratches carry oil, why doesn't the fork tube act like a dust magnet?I would think that some of these dust particles would then be carried back into the fork, then washed off by the oil. The oil would become dirty very quickly.
How do you think the rings are lubricated on a 2-stroke?Originally posted by steve.emma
Cylinder cross hatch is important on 4 strokes to retain a tiny amount of oil on the cylinder wall for ring lubrication, this obvouisly dosen't apply to 2 strokes.

I. I have just purchased a 2003 KX-500 and wanted to know where to find out what plating is used on it
