Hey y'all, just bought my wife a blue 400 HO Friday, it came with a set of 14 in polaris vader chrome wheels and maxxis bighorns on it. It has 2.1 hours and 10 miles and it's slipping pretty bad when takin off in high range. It engages at about 1450 rpm or so in low and reverse but won't start moving in high until about 3,000. Do ya think these heavier wheels and tires are makin the clutch slip? Stock wheels are 12 inchers. Should I look for a HD clutch kit for it or is it just a break-in thing? Thanks for any help with it y'all!! Happy trails!!
