benifits to 416

[Quad Dude]

i got a 400ex and have been looking for more power anywhere. top end low end just more power. i already got a 11:1 stock bore with a web cam, and pipe. i just wondering if i were to put a 416 big bore in if it would make any noticeable difference.

i guess i just make one post so heres another question. on Powrolls web site the have a stroker crank and say that it will take a stock bore 400ex to a 425 with a 4mm stroker crank. would this gain me any more noticable power. i should get more torque out of it but i think it will rev slower. any extra insight on either would be help full. what im looking for is a flattrack motor

Go 416, head porting and bigger carb. That should feed your hunger for power... Not sure if you have a full exhaust but that will elp also.
