Hi new here, new to atvs in general, my wife and i bought a 570 sportsman and thats when i found this site. but my questions are about our newest member, its an 03 330 magnum 2×4. looking for advice on simple mods that will just help overall, its for our son, but i want it to run good. i have to dig into the clutches, any upgrades to that would be great, probably needs a new belt, assuming springs and buttons in the secondary too, and just a good cleaning. how about air filters? aftermarket? k&n? it needs a filter anyway. any other hints and tips are welcome, thanks!!
