KFX400 low end

I have a bone stock KFX400 and I like the powerband. I would just like a little more grunt on the bottom. What is the best to gain on the bottom?

I ran a 155 main jet and it ran all right.
I did not change the needle or air screw until I piped it.

I will try it.
What pipe did you get? Do you notice a big difference?

I got a CT pipe, and I am very happy with it.
It looks, performs and sounds good. Not to loud.
It gave a bigger hit in the mid range and pulls better through top end. Easily revs to the rev limiter now.
