Off the subject but is it ok to take these through water crossings past the bottom of hub? I think I remember in the owners manual stating to not go any deeper than bottom of hub.

I think you need the KWI primary and secondary to run the Pro R belt.
Yes, we have ran this setup with the old factory primary and it works fine, it will work with the updated primary as well.
Thanks, KWI did say it would work before we order the setup through my dealership. Just wanting to keep the cost down and get the 15% reduction. If it wasn’t for the huge rebates before the stop ride was lifted an extra $5K would put you in Mav R territory. But no one has really ran this setup that we could find. Billet primary may still be in my future if I love this car.

After you have some time on this set up we would love your feedback!
I will for sure, even my dealer wants to know how it works out. They had KWI come out and get the primary clutching sorted out for our elevation in Utah and the setup is a huge improvement with just the weights. They were running 34” Rogue sand tires, not sure the paddle count. It rips, but not a Mav R killer yet. It is to hot right now to go to the dune’s. I plan on running it stock at the dunes with the stock belt for half the day then swap to the Pro R belt and see what temps, RPM’s, engagement etc will be. I don’t plan on any power adders until they get the supercharger gearing dialed in. Hope to run 35” STU paddles and 36” rock tires and clutch it somewhere between them. If the stars align I can pick the car up this weekend and maybe we have the dealer do a couple drags with this setup against a stock H2 and Mav R. Not that a drag race means much, but they have done quite a bit of it so they could see an improvement or detriment to the car with this set up. So hoping to love this car, this whole clutch issue is a real bummer for us and Kawi.

Man I feel like a greenhorn beginner here (and I am).
Most of you guys posting here at are a whole other level of experience with these 4 wheelers!! My last trip to the dunes was 2015 at Dumont. I swapped back and forth between a knobby and paddle when going between the dunes and Death Valley.
My last trip to Glamis was in 2008 and I had my highly modified KFX 700 and KTM 300. After numerous close calls I called it done.
My point being I'm thinking on running stock clutch for at least one full season before thinking of any modifications to it. That is unless it gets to where I'm having heat issues.

Some of us have been doing this since the Yamaha Rhino.
I really hope the clutch issue is fixed for the average rider. I have watched a ton of videos and the guys at slick rock are local to me. I think the slight gear reduction is going to be the setup with 35”-37” tires in Moab. My x3 was super low geared in low and turned 35’s like stock tires. H2 seems a little high strung. But that was expected and wanted with the H2 motor.
I’m thinking about a new H2 and I’d be interested in clutch upgrades. However, $5500 for clutching is a no go for me. I’d likely just buy a pro r instead.We have been running and testing the KWI Primary and Secondary setup for a while now and it’s working great!
We have it setup for 15% gear reduction and are still able to hit 100 mph.
It’s now finally available to everyone.
Fusion H2 System Bundle
The KWI Fusion H2 System Bundle is the most complete, most capable CVT upgrade available for the Kawasaki H2 platform. This fully integrated system combines the Fusion H2 Primary Clutch, Fusion H2 Floating Secondary Clutch, DR3 Groovix Helix, Kwik Change Belt Tool, Quick Release Helix Cover, and...kwiclutching.com
I’d like to focus more towards Rock crawling than open desert. I don’t need to go 85+.
Question: Is there a more reasonably priced upgrade that will address belt temps and provide the 15% gearing reduction?

I would just leave it stock and try it like that. So far I'm very happy with mine. Both low range and high range work with no overheat issues.
I don’t disagree, but I’d really like that 15% gearing reduction for the rocks.
We have modified the secondary to run the longer KRX belt and even the Pro R belt but the Pro R belt runs WAY high on the secondary but it works with no issues so far and gets you the 15% reduction.
If you don't mind spending a bit more, you can run the KWI secondary and the factory primary ( I would recommend a billet cap and adjustable weights for the OEM primary) with the longer Pro R belt.

Could you define “a little bit more”? I don’t want to spend so much on clutching that it would make more sense to go with a pro r.
KWI Secondary is $2520
KWI Weights and Hyperdrive Billet cap is $699
Plus the Pro R belt (+\- $200)
What makes the Pro R a more a more desirable machine? and is it going to be the perfect machine for your needs right "out of the box" or are you going to need to spend money on it as well? The H2 is a very capable machine without any modifications.
I’m trying the KWI secondary and clutch kit. I used my rebate money for it. I think it’s going to be great, but a must do? Probably not. With the 27 Pro R Boost release today you will be able to pick up a used one or new last years model pretty cheap. I see literal fire sales going on soon. But if you don’t care to go fast the KRX with some mods are insanely capable in the rocks. Beef the front diff up, which you will probably want to do with the H2 as well since they share the same front diff and enjoy.
Side Note
It will be interesting to see if the new two seat H2 has any different cluching, cover or cooling. It would be awesome if they released it at 280 HP just to mess with Polaris. By the way the new boost has bigger clutches and belt plus 3 intakes and two exhaust ports. Hint, hint Kawasaki. I’m wondering if I can copy the KWI secondary cover and print it so I can put an exhaust fan that suck the air out like the old Polaris.
I’m still waiting for you to post results of your testing. I can see the benefit of the KWI secondary that allows you a 15% heat reduction… but I’m not convinced the KWI primary is going to be that much of a game changer. I’m getting ready to go talk to the dealer about taking my money. I want to have a clutching game plan when I do.
