Has anyone used a Polaris 400 4x4 in Colordao above 6,000 feet? I was told you can not rejet them. My wife's is a 2008 400 4x4 with a 34 MM (?) Mukuni carberator. I was told Polaris does not offer a "rejet solution" fo these - something to do with the carb i smade in Tawain or something. The main jet screws in - just like any other Mukuni - had anyone tried rejetting the normal two sizes smaller or otherwise uaed a newer 400 in Colorado lately?

 

it sounds to me like somebody is trying to pull a fast one on you. if it has the regular jets then i wouldnt see a problem.
