well providing plugs are good and wires are on tight
check fuel pressure should be39 to 41 and hold steady

 

Mine feels like that after going down the roads eating dust from the xp's. lol My buddies seems to have lost a little power after he put a snorkel on.

 

I suspect that your snorkel's or your clutches might be slowing you down. My two-bits......

Cheers

 

i will check my plugs and wires, maybe its time for new plugs. the snorkels have been on for most all of its life, so it did work fine before. what should i look for in my clutches? bad springs maybe? i cleaned them up just before i rode last

 

When I referred to your clutches, I was alluding to the fact that the OEM clutches, as delivered, are not optimized; in fact, far from it! That's why there is so much discussion about clutch-kits on the Forum. To summarize, let me say this: there is no better Performance-Improvement that you can make to your RZR, without resorting to Big-Bore kits and/or Boosting, than a good after-market clutch-kit. I, and several other Forum members, have installed the custom clutch-kit from SLP (Starting Line Products) and we couldn't believe the difference! It turns your RZR into a whole different machine, performance-wise. As an example, watch this video:

These are two otherwise stock, same-model RZR's, with one having the factory clutch, and the other having the SLP custom clutch-kit. Proper clutching does make a difference!

Check your throttle cable to..It will stretch

 

Good point, Ji, and one that's often overlooked; if the throttle can't open ALL THE WAY, you won't get maximum acceleration or top-speed out of your RZR!

Cheers

 

clutching is definately on my list, just not sure who, SLP is nice but $$$

as far as the cable, do you just tighten it up a bit on the fitting right by the throttle body?

 

10mm and 8mm wrench. Back it out till the rpms start to pick up, turn it back to idle, lock it down. At the throttle body..

 

So last night i checked my throttle cable slack, wasnt to bad. maybe a 1/4 inch of slack at the most, i tightened it up to about 1/8 inch play. Hopefully that is all it is. Otherwise, maybe my clutch springs are getting sacked out?

 

At 2400 miles, I think that your clutches are definitely due for some TLC; the springs and components DO wear over time. You don't say if you're running a fairly new belt, but you might also want to look at that. But again, an aftermarket clutch will do more to restore the vigor to your otherwise-stock RZR than any other change you could make. Think of it as Viagra for your RZR.......LOL. My two-bits............

Cheers

 

Thanks BarRZR, I do have a brand new belt on. Does it seem odd that my springs would be sacked out in 2400 miles?

Given the otherwise-proven inferior quality of Polaris springs, I would say NO! As a perfect example, look at their crappy suspension-springs; mine were badly sacked-out at 200 miles! In addition to their poor-quality, the clutch-springs have to run in a much higher-heat environment, which shortens their life significantly, not to mention that they are required to constantly and repeatedly go full-cycle (full-compression to full-extension) countless times during a full-day's ride. It's rather a wonder that they last as long as they do! Just my two-bits.........

Cheers

 

Awesome, I agree. I am used to snowmobile clutching, which seems to last about the same. Lucky we have the aftermarket to look to.

 

you should be replacing clutch springs every year also their are a few high wear items in your clutch... buttons,rollers.pins,bushings that need to be checked

 

In looking at the SLP clutch kit on their website, there are 2 for the 2010 RZR-S for trail riding. One says 0-4500' and the other is 4500'+. Is this for the elevation that you will be doing most of your riding??? Thanks!

 

yes

 

Who has the best prices on the SLP clutches? I'm thinking of going with the 41-810 kit.

Take out your spark arrestor from the muffler and clean it off.

 

Thanks for this thread. Reminded me to check my throttle cable. I definitely had too much slack (100 hrs). You could push the gas and see it NOT pull the cable for the first inch of travel. I didn't like this as it tends to cause me lurching, and perhaps limits my top end.

Anyway, I checked the manual, pg 96, and it gave clear instructions for how to adjust. I tracked down the cable, but on my 2011 RZR S, the adjustments were behind some big vent tubes, which were a pain in the butt to move far enough out the way. Anybody know an easier way, please share!

I backed out the adjuster to the limit and it was much better. Still had a little slack, so next time I either need to shorten the other end or get a new cable.

Thanks.

 

Check your spark arrestor in the exhaust. Mine was plugged up at half the mileage. When i took it out it was like a new machine.

I raced a buddy in a S model this weekend, bottom end we were dead even, he would finally pull away slowly on the top, but not much, and thats with my new tires which are supposedly much heavier than his almost bald stock xct 900's.

I cleaned my spark arrestor, it definately had some grime on it, but not too bad. going to get a service kit for my diffs/tranny/and spark plugs tonight. Hopefully this weekend will be a different story. And a Dalton clutch kit is in my near future.
