i have a 400ex with a 440 kit and it has an 89mm bore and an 88.95mm piston right now but i want to get the 460 stroker and it requires the 89mm piston that hot rods offers for the kit but i was wondering if i would have to bore it out again to accept the larger piston because i thought your suppose to have a little smaller piston than the bore
