1998 RM125..chrome cylinder or not???

[500 dirtrider]

My son's buddy just blew the top end out of his '98 RM125. I tore it down, and we're going to get it fixed but I noticed that it didn't have any cross hatch marks in the bore. It is either in dyre need of freshening up, or it's chrome. Anyone know? :confused:

i would think its a plated cylinder-if its got no cross hatch then i guess its replate time.

It will be nikasil coated and you can LIGHTLY hone it.

Yes its plated unless someone put a sleeve in it. I have a 97 on the original bore and i can still see the cross-hatch marks.

I have had Kawasaki cylinders before that were plated and I don't remember there being any cross hatch marks in the chrome. Am I mistaken, I thought that the chrome cylinders were smooth..but hey, you guys are the experts, tell me if I'm wrong! Anyone know that the diameter and tolerance of the bore is?

Plated cylinders still need the hatch marks to seat the rings.
