Ok, well some of the first mods you can make since it already has the intake/exhaust/jetting covered are simple things like flipping the wheels (new valve stems needed, check the tutorials, or use the search function for specifics), making sure your CDI casing isn't wearing through (under the bottom of the quad, seat area, common problem area w/ warriors), Tires if needed, with your riding conditions, I would look towards, Holeshot HD's (which most on here swear by), or the newer Holeshot GNCC**, or maybe the iRazr** rears, or the Razr2's.
**No one, as far as I know, has tested them on here yet. Since they haven't, we don't have a good review of them. But a Lot of people outside our site like them.
As far as shocks go, recently a lot of us have been pushing towards the banshee shocks. Concerning the fronts some say they are an inch longer, some say they aren't... But they offer a slightly stiffer, though most say better, ride. The rear is a direct swap (heat gun needed, just to heat up a section in the air box, and compress the rear to push a minor dent into the air box for the ressie). Everyone that has done the conversion says they are completely happy, and wish they had done it earlier.
Those mods, other than an oil cooler (we'll get to that later), should last you quite a bit of time.
Right now I'm inbetween 215-220, and though I push the stock shocks hard, I haven't bottomed them out that many times (2-3 times, but I'm not Trying to do so). I have hit table tops, and doubles that have been 20-25+ft. as long as you clear it, and land where your supposed to, your fine.
