need more power

[gotsand400]

i have 02 400ex with a 440 kit. its has a 89mm 11:1 piston.
i would like to go to a 14:1 piston. just wondering if anyone is
running a 14:1 in their bike and what they think about it? can the bike handle that and where can i find one?

I don't have one, but i know your going to need a new rod, and heavy duty head studs. Also im not positive they make a 14:1 but i am pretty sure there is a 13:1.

I'm sure you have a cam, if you don't that is something else you can try. Also if your running a stock carb you can get a bigger one like an FCR 39 or something to that effect and that will give you some more top end i believe. Or you could stroke your motor, and that would add alot more as well.
