I am not sure how much they do with 2 stroke pistons but

CP pistons is probably the top custom piston manufacture.

Hope this helps you with your search. With what I understand the rod is same as
ROD KIT FOR GASGAS EC,XC,DE,MC,SM 250/300 .ALSO FITS 84-01 CR250 ,85-86 ATC250R,86 TRX250R.

that certain bigbore pistons for the oem 250r will fit. now 72mm stock gas gas bore is a pretty big piston making the 250r also like a 300. I have not seen any bigger but there are allot of 250r parts out there.

Well I don't know wtf happend to the post I tried to post.

ROD KIT FOR GASGAS EC,XC,DE,MC,SM 250/300 .ALSO FITS 84-01 CR250 ,85-86 ATC250R,86 TRX250R.

From what I have heard the pistons from some big bore 250r will work in the GASGAS

hope that helps your search

Glad you found it, who makes the piston? So you are just running a stock jug bored? Did you need to run a spacer plate or a modify head?

when i bought the bike it came with 330 kit ,it been bore and the o ring has been regroved in the jug. the head is bigger to fit in the jug, it the one on the right in the pic. no spacer plate ,and here the piston that i order .http://www.lasleeve.cc/index.cfm?eve...roduct_ID=2012

Ok Thanks, sounds like a little bit of work. I was wondering what they did with the head? I think the head is original of a bigger motor anyhow just not sure what? lol

I was looking into making mine a stroker.

Are you still running stock carb & pipe?
