WTB 250r Cylinder Big Bore Or Ported!!!!

WTB 250r Cylinder

I just blew up my stock engine... Melted the piston and scratched the cylinder.

Anyways I am looking to buy a used or new cylinder that either does or doesn't need to be bored for a new piston... But It needs to be a big bore cylinder preferably under a 330 to avoid any case work... Ported would be a plus but anything will do.

Also I would sacrifice the big bore if you got a nicely ported stock bore (or close to stock bore) cylinder



Thanks!!

I've got this MX ported 86 TRX250R cylinder. It has a custom aluminum sleeve and Nikasil bore on it. Cool thing about it is you never need to bore the cylinder unless you really blow an engine up. Normal rebuilds are just a new piston and rings. $250 shipped, comes with a fresh Wiesco piston kit too.
