Just wondering what anyone has done to their 400 Sportsmans, or any other quad with the 425 in it as far as motor mods go to give them some more snort. I'm not really in the market for a new machine yet, as I'm going back to school this fall, (after a six year hiatus, lol), but I'd like to make the thing run decent as far as power and mudding cababilities go. I've looked into a set of 26" Mud Lites on ITP rims so far, but haven't bought anything yet. So if anyone has some tried and true motor mods, clutching, or what have you, let's hear 'em! Thanks in advance.

 

a clutch kit would give you a little bit more snort, or at least i would think it would....do a search and see what you come up with
