My wife rides a 2001 Trail Boss 325, and seems to always get stuck in the sand dunes. It is strickly stock, and running ITP Mudlites front and back. So she winds up riding my 425 Magnum 4x4 when riding the dunes and I want it back :y: First of all, I'm going to install paddle tires on the rear, and the sand tires on the front. What I need are some suggestions about getting more power. Free flow muffler, K&N filter, maybe some carb jet work? Looking for suggestions.
