02 yz250f big bore help.

Recommended Posts

Has anyone on here ever successfully installed a true bolt on 290 or 269 kit that didn't have any head gasket issues? I'm currently having issues with a tusk head gasket, ( ill be goin back to a oem head gasket as soon as I get the time )  but I would like to get a big bore kit but all I see on here is people with head gasket problems that have installed a bbk. Any info on this would be very helpful, cuz I don't want a bbk if im jus gonna have the same 'ole coolant loss issues due to poor quality bbk head gasket.
