hey guys i have a 1999 RMK 600 and i was wondering what are some worthwhile upgrades to do to it, i already have vforce reeds, dg exahust, and a k&N air filter with a prefilter. if you could post a link to the upgrade that would be apreciated.

Do you use it for mountain/deep powder riding? or flatlanding trails?
I definitely agree with clutching. Either get a kit, or do it for cheap by learning the clutching principles. Even just a stiffer primary spring can do wonders, with a higher engagement it really gives the sled lots of holeshot.

those air pods are robbing your HP. And re-clutch it, re-gear it, high octane head, and keep it jetted properly. You will feel a difference.

but are you looking for bolt ons only or more in depth stuff?

i use the sled more for mountain riding and powder and i was looking in the direction of more in depth stuff and if you do have a good bolt on upgrade I'm always open to ideas. I have heard alot about re-clutching and stuff like that and i honestly dont know to much about it so if anyone has a good website that could inform me about this stuff

Here is a good site with lots and lots of useful tech/tuning info for mostly Polaris sleds. It touches on cluthcing a little bit in the first section at the top of the page, "The Holeshot". Also has suspension tuning, and a gearing ratio chart.
I also suggest getting your hands on a copy of Olav Aaens Clutch Tuning Handbook. Read it twice. It's aimed more for drag racers, but that's okay because it gets very in-depth.

Like mentioned, those k and n filters aren't doing you any good, put a stock airbox back on, especially for riding in the powder.
