Hi everybody, I am looking for some insight and a second opinion before i dive in ordering parts and trouble shooting. Looking for the clutch gurus on here. I have searched but cannot find a thread with my issue.

I have a 2008 sportsman 500 HO with the non-EBS clutches. The quad has been neglected for the last few years and used mostly for snow plowing and hauling firewood by my father. For a long time there has been an issue with the clutches where they would slip as the secondary would start to shift, but for his use he never noticed/cared.

Now I have the quad and have been giving it the TLC it deserves. I found the buttons in the secondary to be completely toasted so those have been replaced along with the proper EPI clutch kit to turn the new 27" tires.

The quad felt pretty good driving around the block but when i took it out for a real ride it slips like crazy! Engagement is around 2000rpm when watching the clutches in neutral but the quad isnt going anywhere until 4000 rpm in low or high range on the trail. Once the secondary starts to shift everything feels right and there is no more slipping. Taking off feels like im slipping the clutching trying to start in 5th gear on a motorcycle. Nothing seems to be binding in the clutches. Motor mounts are good.

The belt deflection seems way too loose even with only one shim in the secondary, can almost pinch the belt together. The clutch center to center seems fine at 10". Also the engine braking seems much stronger than I would expect now.

The primary seems pretty grooved just above where the belt rides, right now I suspect this could be the issue but I do not want to go and buy a new primary if it isnt going to fix this.

Any thoughts would be much appreciated because I am running out of ideas!

I have a 17’ 850 XP, bought it used with 350 miles. Ever since I have owned it i have noticed a very high pitch vibration in the handle bars. I am wondering if this is normal, and just something with the front gear case?

It will sometimes go away breifly, not sure if it has to do steering/alignment or if something else may be going on. I am kind of hyper sensitive to this kind of thing....especially on a new quad.

I have a new to me 2012 Polaris Sportsman 850 Ho XP it has STI wheels on it with Swamp lite, 27/9x14, 27/11x14. The rears have a spacer under them and I was wondering why this would be needed??

Thanks in advance, Kevin

Is it better to buy OEM parts or others?

For example if I'm going to change the belt on my atv what do I choose? Ofc oem most of the time are more money but is it worth it.

also what aftermarket brands are good?

what light bar have you guys installed in the 500/800 factory bumper? i’m looking for the best fit with minimal modifications needed (don’t really wanna cut or drill the bumper any)

Just bought my first ATV a2007 outlander 500 2up

Of course it happened at the most in opportune time. Slid out of some snow tracks and onto the side of the trail which dropped off. When I went to winch up the winch wouldn't pull out. Luckily one of my buddies was able to maneuver around to winch me out but it sure would've been easier on my own.
So then I get back to the garage and when I test I hear a click but it won't go out and the lights lose a little bit of brightness. What is super weird though is that I can't turn the freespool knob at all. It is stuck good. Any suggestions?

I'm replacing the outer CV Joint on my 2005 Sportsman. I have the axel hanging free (tied up) pulled the boot back and cleaned the grease away and fond the clip. Can move the clip. Tried putting a pipe wrench loosely around the shaft and hammering in it, but will not come off. Any ideas that might help me. Thanks John

Hi I just registered for this site because I have a 1985 Polaris three wheeler for sale hopefully somebody on here appreciates what I have to offer
