440 kit worth it

[rhoadsM125450]

Is a 440 kit for a 400ex worth it...:confused:

Yes:)

I have the weisco 440 kit with 11.1 compression. I also put in a cam. I dynoed my bike with just a a slip-on, k&n filter and it put out 25Hp. With the 440 kit and cam and header I got 32 Hp . Next is a carb. I'll post my graphs tonight.

That depend on what your are looking for out of the motor. We build alot of 416 and 426 motors that are faster than the 440. Give me a call and I will give you some options.:)
