[KASCHAK]

how much hp gain do you think you would get for a vfoce if I put a full yoshi exhaust system a k&n airfilter jet kit. it has around 42 stock what else would i need to do to get some real good bottom and mid end.

my friend got to WB on his and it made a huge difference but i think yoshi it better so it should improve it even more

Try looking for a clutch kit for it, I know hot seat makes a lot of them for polaris's and they really help the pull off of the bottom.
