Example: Wiseco 801M06850 for a 2002 CR ready for installation.

Faded,
Did you chamfer/debur the holes you drilled?

dirtbike_madness said:So, I talked to a friend of mine at a Honda dealer, and he recommended the OEM piston, and here's his reasoning.
He said that since the Weisco is forged, if it does go, it goes in a big way and can destroy the cylinder. Because the cylinder is nikosil coated, it cannot be bored. (is this true-anyone know that for sure?) The OEM piston is cast, and will not cause the damage that the Weisco will if it goes south.
Swain Tech ( www.swaintech.com ) did the coating on the piston. They used their PC-9 on the skirt and TBC on the crown. You can click on the link to read more about it if you're interested.jmossbarger said:Nice skirt coating, what did you have put on it? Who did it?
This is the first time running w/the coated piston. Currently I have about 3hrs on it including break-in and riding an unfamiliar track. Lots of changes after this rebuild so it's hard to comment on performance of the coating alone but the bike runs really strong. Price was $35 for the coatings. I've heard mixed emotions but it was one of those things I've always wanted to try myself, so I did. No plans to ride really soon either, still waiting on the weather.Studboy said:Have you ran the coating before, and if so, can you tell any difference in longevitey or power? What is the pricing like?
