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!!

First off ..I would take it to the dealer...did you go stock size or over size...did you have the wheels put on or did dealer put the wheels on before you bought it..if the dealer put them on...its there problem why its slipping...but take it there ...dont burn your belt up

Yeah the stock tires are 12 inchers and these are 14 inchers on it, dealer put em on it when we bought it, financed with the quad. If that's what is makin it slip it sure will be goin back to them and I'll make them upgrade the clutch. This ain't gonna fly lol

Yeah the stock tires are 25 inches y'all and the bighorns are 26, wouldn't think an inch of height would cause it to slip like that! No water in the belt housing so I'm outta ideas lol

12" and 14" makes no difference in rim size..the tires for a 12 or 14 are the same size height an width...a 26" is 26" high no matter what..a 14 has less side wall is all.....but i would take it there first..may be just a clutch adjustment....

what size tires are on it now..not rim size but tire size.....

ok seen you posted as I wrote..no 26 wont make any real difference....now let the dealer figure it out....

I dont believe its the tires....so use your warranty an have it checked.....and if belt is burnt say you want a new one....it should engage in same rpm forward also....or close....something is off kilter..lol....

That's no good, sounds like a bad clutch, dealer should take care of it, still a pain in the rear.
Should it not be easy to roll in neutral.

I'd say you have a clutch issue, but the tires you put on are definitely much heavier than stock so you may want to consider a clutch kit in the future too, as you will likely continue to have the issue without changing something. Have them try the primary spring from a 500 in it and see if that helps if you don't want to spend the money on a clutch kit. FYI a QSC kit for the 400 is $319.

No it should be, some times you get crap in between the rotor and pad and it can cause the problems having is having .

How hard is it to change the clutch? I'm almost positive that that is where my problem is because it takes off ok in low and reverse just slips taking off in high. And special tools required like a clutch alignment tool or anything? thanks for all the suggestions y'all!

Removing the primary requires a puller. Secondary just sides off its shaft. Installing a clutch kit doesn't require any special tools. But you will likely want to put on a new belt too at this point.
