If you don't want to spend the money just yet, rejet to a 155 main, remove the airbox lid, and put on a 13 tooth front sprocket. Removing the lid and rejetting will give it about 1 hp, and give it a deeper, throatier sound. The sprocket allows you to use more of the engine's bottom end torque to your advantage although you do lose some top end. I do most my riding in the dunes and keep up with mildly modified banshees and raptors, and smoke the predators on the shorter hill climbs we race on.

I ride my Z mostly in the sand, and I have seen no signs of sand getting in to the airbox since I have taken the lid off. Before I ride in the dirt again I plan to buy the Pro-flo adapter with the K&N and the outerwear, and I won't ride through any deep water or mud

i think you should put a white bros. E series pipe, k&n air filter and and DG baja series skid plates because I broke my stock plastic one backing over a rock. These are the same things i put on and they work great!
