on my 08 Kingquad 450, sometimes when im and a dead standstill and i accelerate, there is sometimes a small delay and a loud squeak or something rubbing. its got about 880 miles on it.
what is this noise?

maybe the drive shaft or differential? does it have the cvt tranny? belt could be squealing. my buddies eiger does it too. from a dead stop the belt is disengaged. once the rpms get up to speed the pully will grab the belt and it will squeal.

I'm guessing that this happens more if you come to a quick stop, and try to take off again. This is normal "belt bark" and happens because the secondary spring is not stiff enough to allow quick backshifting when coming to a fast stop. I had this happen all the time, until I added a yellow EPI spring. I rarely hear that noise anymore.
Your particular CVT has the belt always engaged because it has the internal wet clutch doing the engaging. That gives you engine braking also.

ohh so its not bad? that sounds right thumper. it dosent happen all the time but if i lock up the rear tires and skid to a stop, it always makes the noise when i accelerate

That's definately what's going on. It will especially bark when you skid to a stop, and then try to go again. It's just the stock secondary spring not backshifting quick enough. It helps if you want to skid to a stop, if you slide ALMOST to a stop, then roll a foot or so, then stop completely. This gives the spring a chance to backshift while moving a little, and then you shouldn't get the bark. Not a bad noise at all, pretty normal for a stock clutch.

 

[KMGLTZ]

so would stiffer clutch springs solve this problem?

 

[Dprisinger]

To address the squawk or bark, the secondary spring is what needs to be changed. While you're in there, I would put in some ligher rollers for better acceleration. But that's just me.

 

[KMGLTZ]

yeah, ill do anything for better acceleration, where can i order these parts and how much are they going to cost?

https://www.erlandsonperformance.com/mm5/me...t_Code=WE493004 EPI has lots of kits to choose from, depending on what your needs are. If you just got the spring and rollers, it's closer to $100.

Such a very amazing link!

Often times, cvt's will do that just because the clutches are dirty. Most any of them will do it when you skid to a stop, but if it does it any other time, it's usually just needs the clutches cleaned.
