big bore

does anyone have a eric gore big bore kit on there bike? looking at the 420 kit for more power. is it comparable to the 426 in power?

yes, yes, yes

Second Kevin above.

Eric actually rebuilt my crank with the 426 rod/bearing/pin and sent me a nikasil coated cylider that had been bored out to 95 mm. So I'm actually at ~ 426-430 cc.
