Okay. Have you really rode this quad yet? Is this your first quad? What do you see yourself doing with it (i.e. racing it, just back woods riding)? I see you just got the 450x shocks. You shouldn't have to revalve them. I race mine here and there with the shocks, and they are just fine. The suspension does suck on this quad, but it still does it's job. Next, everyone says the sway bar. If this is your first quad, you can learn how to turn with out it. Besides, with it, the comfort isn't as nearly great, and you feel a lot more. I have a PRM skid plate, and I like it a lot. It wasn't pricey, and it is one complete piece unlike some others. Whatever tires you are looking to get, I would try to be sure they are 6-ply, so they last longer and are more puncture resistant. Now you can do numerous things for power upgrades, but with this being your first quad if it is, I would get a feel for how it is now. IMO, tires would be the first thing, and then go from there. If money is no issue, then by all means go for the other stuff. For the average rider, there is no need for 3k or more worth of suspension, unless you just have money to burn. Another upgrade that I personally put on everything really soon after getting is nerf bars, I dont know how many times they have saved my leg from hitting a tree or something else.
