Ring survey

Post by canyncarvr »

How many y'all have seen moly rings for the KDX?

I just got a set (Riken) that IS moly-coated. I've only seen shiny rings. Don't know what the metal is..but it's not the gray color that molybdenum is.

Just curious.........

Thanks!

CC,

If they are what I am thinking, they are a iron ring that has a break in coating impregnated into them. Much like the "parker-lube" that a lot of camshafts are treated with.

A lot of 4 stroke one piece oil rings and scraper rings are made this way too.

Thanks for that. That is what it looks like, now that you mention it.

Ha! I remember some guys trying to scrub off such cam coatings..thinking it was some sort of protective layer that had to be removed before install!

No..I wasn't one of 'em. :wink:

Does that make these rings odd? Different? Better or worse than...well, whatever make-up it is of the more common (common because that's all I've seen) shiny rings?

Thanks!

CC,

They will break in sooner and give a better seal right off the batt. They will wear a little faster (not a lot), but it will be easer on the bore (which will make the bore last longer).

It does not make this type of ring odd as this method has been used a lot for many many years (40 plus as I can remember)

"Riken" has been around since the late 60's and make a lot of OEM rings.

They are a little softer and again will wear a little quicker that their Kawasaki counter parts....., but very good rings.
