WELCOME! You have found a great forum and a legendary bike.......

The bolts are at the back of the seat, going through the side panels. Remove those, lift rear of seat and pull back (away from tank).
Buy a new air filter, preferably 2 or 3. Maybe a pre-oiled, like the No Toil, for your first change. They can be cleaned a re oiled a couple times. Have one for a back up, this time a standard (not pre-oiled), practice oiling and "drying" this one.
Also, your jetting is probably off, so be prepared to go through the jetting guide.

Where are you from?

Was the bike doing that when you bought it or did it just start since you brought it home?

Fresh gas?

I would plan on cleaning the carb. That will also give you a chance to find out what jets are in there.

Twin Air, Moose and No Toil's "premium" filter. Are [what I consider] to be the best filters. I've had bad luck with Uni filters coming apart after the first wash. The Pro X filter seems similar to the Moose filter, but I haven't used one...yet.
The No Toil Fast Filter works great in a pinch and they can be washed with dish or laundry soap and re-oiled a couple times. In the wet conditions that I ride in I've never had a problem with using them. Last top end that I did, after 5 years of riding, there was no signs of dirt in the intake or cylinder.

As has already been recommended, following the jetting procedure will get things set-up properly. I wouldn't rely on generic settings. Even at sea level, I would bet that the 160 main and 48 pilot are too rich.

This will do it: http://www.kdxrider.net/forums/viewtopi ... 105&t=1156

If you have a shop close by that has a good selection of jets, then I would get a couple of jets leaner on the main and pilot (like 158, 155 or whatever the actual numbers are). But if you need to order jets, like from jetsrus.com, then I would go at least three leaner because of the time and expense of shipping.

That air filter test is why I bought 2 Moose Racing filters for my sons 05 KDV 200. It's the only test of air filters I have ever seen.
Whoa that was close!!! Damn kid is too fast for me to try and keep up to.
