big bore kit for 250r
In my opinion I would go with ESR. There big bore kits are less expensive than any other company out there, and work just as good if not better. products, they use a PRO-X cylinder for all there big bore kits. For $999.00 you get a 330 or 350 pro-X cylinder ported and polished your choice, plus a power head with 2 dome's for race or pump gas. I have had mine for 2 years now and it works great![img]i/expressions/face-icon-small-smile.gif[/img]

big bore kit for 250r
I have a 425...i pull wrist pins in half and stretch rods. Everytime it does down it costs me 500 bucks to rebuild it...plus it goes through a clutch ritually. i have a gas 370 (pro-x) that hauls some azz and was a lot cheaper to build and seems to be more reliable (except it eats reeds). Id stick with a pro-x unless going to methanol. If your going to methanol stick to a unstroked crank. FYI, PSI is rumored to be going out of business. If this is the case forget about getting cylinders/heads/ect.
