265cc Piston?

Recommended Posts

I need to order a new piston for my YZ. It has an Eric Gorr 265 job, and I'm not sure which piston I need to order. I believe it would be the 8-over kit, but not positive. Any help would be great, thanks. I tried emailing Gorr, but, won't work.

.080 is the correct piston I believe.. I use a .160 over for my 285.. I think :) Dang, I cant remember now... :banghead:

.080 is the correct piston. Check the Wiseco web site for the correct piston part # i.e 99-01 and 02 + they are slightly different.

It should be a 68mm piston. A piston fromthe early 90's is what I think they were using.

Bad info.:)

It is actually 68.5mm Diameter. Produced by Wiseco specifically for the model bike required.
