Hey everyone,

I just purchased a used RZR 800 and I am curious to what clutch kit everyone recommends? I am primarily a trail rider with some mud but mostly solid ground. I am looking for a good smooth take off and deceleration. I like a smooth engine breaking not the jumpy feeling where the rear tires are catchy. The tires I am running are 26" maxxis Bighorns on 14 in wheels. I did happen to watch the video that ATVTV.com had on the SLP clutch kit for the RZR 570 which sounds very appealing if it was for the 800. Anyway, thanks in advance for the suggestions!

racrawfo,

Selecting a clutch kit is very subjective.

You want "good smooth acceleration and deceleration"

The Team primary clutch is designed to keep the motor RPM at the peak output throughout the driving range. That's what the spring and weights in the Primary clutch and the spring in the secondary clutch work together to do.

So...if you've added engine components that change the RPM where the motor makes peak power...then there is a clutch component change necessary. The manufacturer of the motor components should be able to provide clutching recommendations.

If you've dramatically changed the weight of the machine...you ride loaded...or you've made a big change in tire diameter or width...then you probably need some clutch component changes. Tim (Swing Arm 1) is a good resource for clutch components, so is Todd at Hunterworks, so is Matt at Holz Racing Products. There are lots I've probably missed.

Now engine braking, that's much easier. There are two very quick ways to get engine braking. Put a "one way" bearing in the Primary clutch and two, put a EBS (Engine Braking System) helix in the secondary clutch. The primary clutch takes some specialty tooling, but it isn't hard to do and the tool is available from Starting Line Products. The one way bearing is a Polaris part.

Just a few thoughts,

Roger,

I've never tinkered with a fuel programmer.

If all you have done is change the exhaust you may not need one.

Two things I would do:

Call the exhaust manufacturer, talk to the tech guys and see what they tell you no Air/Fuel mixture and need for a programmer.

Keep an eye on the color of the exhaust tip. For most RZRs it will be black. Optimum would be a "hot cocoa" color.

Lean and it start's to turn white-ish. Going lean makes more power...right up to where the pistons melt!!

Just thoughts (and yeah, had a friend melt the pistons in his Harley one time for going to lean!)

I think the best thing to do is understand what you have and then what you want. Meaning what engagement are you at now? What shift out are you looking for? Do you want adjustability or a fixed weight set up? Example, I'm trying to get close to stock engagement and flash to 6100 or close as fast as I can and then it hold there until the clutch is totally shifted out.

I went with a dalton because of the easy adjustment, which so far has been good because I have been adjusting it trying to get it perfect. I'm a special case because I bought a used S the suggested set up isn't right. Not because of the kit or the suggestion. Turns out the rzr isn't putting out the power it should and I had to pull weight to get it where I needed to be. Now I'm chasing the lack of power and will be able to easily add weight back when I figure it out. Literally it takes seconds to adjust the dalton if you have the cover off. Hunterworks has been extremely helpful thru this process! He has spent a lot of time on the phone helping me diagnose problems that are not related to the dalton kit which he sells. You can't ask for more than that!

On the good side I'm being forced to learn certain things that may help in the future, like the intake on my rig lost me about 150 rpm. I would not have known that had I not tested with and without. Next ill know how much a dirty spark arrester cost me. And soon how much the right air fuel ratio is worth. Good thing I like playing with this thing! Lol

Good luck

It's been a long time since I've been on here to post or spend any time reading. This site is still addictive! I finally put on a lift and put on 27s and we've been spending a lot of time in mucky tussoks here in Alaska and the 09 RZR is struggling a bit now in high gear and I'm sure it could be better in low as well.
I could spend many a more nights reading manufacturers websites... I've already kill a few to many nights.
I've never worked on a centi-clutch but I have a lot of mechanical experience and aptitude.
My primary reason for writing is to ask for your experiences with the aftermarket clutch world.
I don't need or want something that needs to be adjusted or monkey with I want to get something I can installed and not worry about. There are several to choose from.
I think if had to choose 3 I would choose Holz, Dalton or SLP (if I robbed the bank); but I'm open to all suggestions if they come with some experience comments.

The knowledge in this site is priceless! Thanks. M
