anyone know what the exhaust o'rings are made from on my gas gas ec 250 they are the 44mmx3mm ones x2 off?

I just went to my local dealer, yamaha, and got some off a 2001 yz250 or 125 I can't remember. I just brought in the exhaust port and matched it up.

Viton, not rubber.
Yep, 44x3, same as the big ktms.

Old mate honda dealer wanted about $15each. Went to the local bearing shop and purchased 4 x Viton O-rings for $2.50 a pop. Shop smart! 44mmx3mm

Yikes, and I thought $7 NZ was bad for a genuine gasgas one.

I bought a bunch from http://www.mcmaster.com/ a while back for the KTM. they have a bunch of sizes and different heat ratings.

Thanks again guys got mine online viton 44x3 10 quid for 4 delivered. 1.50 each and 4 quid postage

where did you settle on?

I use 43 x 3.5 viton o-rings. They seal better over the long run.
Downside - harder to install the pipe.

I did think about going for the 3.5 o rings but figured they mabye too big?
