Any Performance Mods for the Sportsman 400 4X4
My dad has a 2002 Polaris Sportsman 400 4X4, and the machine is great, except for the power. He has the EBS system on it, which is great for down hill, but the quad does not have much power. If you want to climb any hill you have to switch to low before you go up or it will just bog down in the middle of the hill, (engine trying but tires not spinning). Even in low on some steeper hills it bogs. It will bog on flats if there is a strong wind against you. Bottom line is this, anyone know of some performance mods to do to it to get some extra power? Everything is stock now.
