Aftermarket Part
- **2020-24 models us a 4 arm clutch instead of 3 arm, for 2020-24 models, see that specific listing***
- **1-3 day lead time for kit assembly**
- Lock and load your Kawasaki KRX 1000 and get ready for some serious kick! The KRX 1000 is a great machine, but Kawasaki left a ton of room for improvement on the table. This simple kit is the best way to wake up your KRX 1000 as it comes with our proven ECU tunes which are loaded via the DynoJet Power Vision 3 ECU tuner. The tunes add some amazing horsepower from low end to high end RPM and really give your machine that "snap" you're looking for. Our AA Stage 1 clutch kit compliments the tuning perfectly by more efficiently transferring power to the wheels and ridding yourself of the very lazy factory clutching setup. We finish the kit off with the AA KRX slip-on exhaust. This exhaust is just what your machine needs! We set out to produce an exhaust that looks great, sounds great and has adjustable sound levels. For more information on the exhaust features and options please follow the link below.
- Kit includes: AA custom tuned PV3 tuner, Stage 1 Clutch Kit, and AA Stainless Slip-On Exhaust.
- Big horsepower gains at +17-18rwhp, or +25hp at the crank. The KRX factory timing map is very de-tuned which allows us to easily wake things up
- Quicker throttle response and power delivery
- Throttle by wire tables are modified for better response, especially in high range. Low range throttle mapping is a little better, but still left mild for good crawling.
- Full throttle/power in reverse (factory limits reverse throttle)
- AA's wicked timing curve built for 91-93 octane fuel
- A great fuel curve that gives much better low end (as well as all around) power as the factory map is very lean in key areas.
- Accelerator enrichment is optimized for better fueling and vehicle response when stabbing the throttle
- Fan on/off temp lowered to 185/180 degrees Fahrenheit (Stock is 189/183)
- Winter tunes (runs hotter but safe coolant temps) available for those with cabs/heaters in cold climates. Easy to switch when seasons change!
- Seatbelt limiter disabled
- Speed limiter removed in low and high gears
- Rev limit at a safe 9800 RPM (Stock is 9500 RPM)
- Best peak power when tuned is 7000-7300 RPM at wide open throttle around 40-50 MPH in a full power run
- Very easy to use tuner that can also check and erase most trouble codes
- Easily data log 25 parameters with 1 push of a button and review on your windows computer later
- No mess of having to send in your ECU, and a safer way of programming your ECU (easily go back to stock tune)
- Mount using the supplied dual lock Velcro
- Includes Level 2 Tune: Built for an aftermarket exhaust and 91-93 octane. Gains 16-17 RWHP in some areas, and on average 14-15 RWHP when combined with our clutching and exhaust. This takes your KRX from roughly 112 factory rated crank HP to 135 HP.
- Race fuel tune 95-100 octane maxes out our timing curve to where we see peak power. This gives you another 3-4 RWHP on average over the pump gas tunes.
- More tunes are coming, if you have any specific needs please let us know!
- Why AA tunes over others? We have been tuning UTV's with CVT clutches for a long time, longer than almost anyone in our field going back to the 800 RZR. Tuning a CVT vehicle properly is not an easy task as you have so many variables at one time. We spend the time to wheel dyno(with actual UTV tires) correctly per modification, and have advanced ECU calibration and clutching knowledge to do so. Every change in horsepower can result in us changing clutching several times. We also develop most of our supporting mods so we know everything works correctly, and build parts to fit the vehicles needs. Lastly and honestly the most important; we then back up our results with real world data logging on local trails and our facility on 110 acres. It's this combination that truly makes the difference and why AA normally has a faster vehicle with the same or less rated tune horsepower.
- Our Stage 1 KRX 1000 clutch kits pack a huge punch! No matter the terrain, they hit hard and just keep pulling for days. On the trail or at the race you'll notice wicked acceleration and instant clutch response when getting back into the throttle after hammering that corner. In the dunes you'll see the same benefits, but also have much less bogging when climbing that big dune. The machine will hold RPM so you can get where you need to go, and get there faster! Going mudding? Our mud setup will help turn those tires through the thick and deep with much better RPM and wheel speed that's key to climbing out of that hole. Are you a rock crawler? Our smooth engagement and precise feel down low will give you the confidence to tackle any obstacle. We have a huge amount of CVT knowledge, a great passion for the sport, and spent many hours testing different setups in the real world. We know you'll be extremely pleased with the performance gain from our clutch kits!
- The KRX 1000 has some clutching issues right out of the box because the OEM weighs are soft. Being these vehicles are geared so low, the clutch constantly runs at full shift over 55 MPH. Being at full shift for so long wears the weights away at the tip, and will groove them. This makes the vehicle want to sit at full shift, and shift inconsistently. Our weights go through two hardening processes and are through hardened for the most longevity possible. They have no bushing as it's not needed with the hardened weight, which also makes them last longer. Not only that but they are fully adjustable for different tires/modifications and perform better because of how the mass is placed on the arm.
- Stage 1 kits include our AA Recoil magnetic adjustable clutch weights, AA dark green primary spring & setup guideline.
- Our setup guideline will let you know how to set your weights for stock horsepower, tuned horsepower, 30-35" Tires, paddles & more.
- Fully adjustable magnetic weights are easy to use and adjust
- Adjustable from 91-x grams, and up to x grams for turbo applications if you purchase our optional Slug Magnets
- By design, our clutch weights have more tip weight mass, so they grip the belt harder and accelerate faster... yet still crawl even better than OEM.
- A must-have when changing tires, tuning your machine, or running paddles
- Cooler running belt temps from a more efficient power transfer which results in longer belt and clutch life
- Big acceleration gains an better power transfer to the rear wheels.
- Close to stock engagement which is very smooth (Higher engagement springs available if needed for racing)
- Our Recoil clutch weights are easily adjustable with simple magnets. They have a custom AA profile, the BEST coating on the market (nitrocarburizing) which has increased wear resistance, improved fatigue strength, and added surface lubricity. These clutch weights also offer great performance, and the ability to tune for many different applications or modification in the future, without the need to buy extra parts. The magnetic weights are the best option to properly place the mass where we need it on the weight for best performance for your application.
- We found the stock secondary clutch to work very well, this kit is just for the primary clutch.
- Make sure you check peak wide open throttle RPM @ 40-50 MPH, it should be 7000-7300 RPM for peak performance with our tuning. See here on how to test: https://aftermarketassassins.com/tech-blog/f/clutch-testingverification#
- See installation video here: https://www.youtube.com/watch?v=Vop-L1y0IK4 (Video shows 4 arm clutch, installation is similar)

Wright is right
The fact Wright attacks popular concepts of progress is enough to merit five stars.
Until 1955, when I was 25, I naively believed progress was inevitable, natural, and simply a part of human nature and society. I attended the Earl Lectures that year. Swiss Theologian Emil Brunner presented three addresses on "Faith, Hope, and Love" at Berkeley, California. Westminster Press published his series in a book given the same title. I shall quote a few remarks.
Brunner traced the burgioning faith in progress to the nineteenth century, when "Darwin's theory of evolution seemed so to support and enlarge this optimistic evaluation of progress as to see it in a cosmic perspective." But the doctrine of progress is not the same as evolution.
"Although this idea of progress had a success for which the word 'triumph' is hardly an exaggeration, there were warning voices raised against it, voices of men of weight and importance who were not willng to accept the new doctrine," he said. "It was a new doctrine because it was not known to antiquity, it was not known in the time of the Reformation, it was unknown in all Asiatic culture. It was a new thing! The idea of progress became an axiomatic conviction which needed no proof and could not be disproved."
At one point, Brunner said, "Since Hiroshima the world does not believe in progress anymore." The end of WWII was still fresh in our memories, and I suppose that's why he said it. We know, today, that it didn't take long for much of the world to revive and renew its faith in progress. And now it's stronger--and more dangerous--than ever.
I'm not opposed to every aspect of progress. Progress, when it moves in wholesome and healthy directions, is a blessing. I'm glad my dentist is able to fill--and save--my teeth without pain. And when it came time for my doctor to pull my cataracts and replace them with implanted lenses, I marveled at the miracle. It was a quick and painless operation, and now I have wonderful vision.
It's that dogmatic idea of progress based on greed and cold indifference to global warming that concerns me. It's that ongoing waste of limited resources, whether they be animal, vegetable or mineral, that concerns me. We are pulling the carpet from beneath our feet, and the king is pulling hardest of all. And who is the king? Ignorance! Ignorance is king!

My favorite book, in any genre
Ronald Wright is an amazing scholar and writer. His style is fun and easy to read while delivering impeccable historical research. I have listed to this book several times over the years and I appreciate it more each time. I recommend the audio version more than the print version because of the compelling way Mr. Wright delivers this 4-Part lecture series to his audience (now in book form).
Note to Amazon: Please make this book available on Audible, CDs are cumbersome.

How many trees do we have left?
In this book, the author takes a look at the downfall of civilizations. Yes, that's plural. There are several models of how civilization is progressing. One is that we're getting better and better as time goes by. Another, less popular one states that we are actually in decline, going down from some sort of golden age. You'll find many of these proponents in the old age homes and such. For them, the only disagreement is when we are declining from.
Wright takes a look at the cyclical nature of the rise and fall of civilizations, taking examples from several once- prospering civilizations. This book stands as a call to action that something must be done to grow smartly and be careful on how we allocate the scant resources we have left. While he doesn't hit an anything new, this book's strength is its concise nature. The several examples are familiar and in that have more impact.
The strongest example is one he visits several times to show an analogy of current times: Easter Island. This isolated speck in the Pacific was once a thriving mini-civilization with culture and art. And a lot of trees. These trees helped the islanders fish and raise their ceremonial head sculptures. However, these trees also were a poorly cultivated resource. Someone not too long ago cut down the last tree, and the island is now a wasteland and anthropological curiosity. We are doing the same thing. How many trees do we have left to cut?

Good on Review Short on Direct Experience
It is an extensive review of the literature on rise and fall of civilizations with observations on our's. Extremely well footnoted and referenced it however suffers from the author appearing to have little direct primary experience in the study of his topic. Nonetheless there is good information here and substantiation of the notion that cultures come and go, frequently going as a result of the lack of capacity necessary to change group behavior in response to certain challenges. He presents compelling evidence that those overwhelming challenges often revolve around irrational and compulsive exploitation of natural resources.
Sadly I share the author's pessimism in regard to our global culture being likely to respond adequately to the ongoing destruction of our livable earthly environment. I fear the planet is headed for a massive kill off in the disturbingly near future.

I hate to be the kind of person preaching on Doom's ...
This is an impressive quick read. I hate to be the kind of person preaching on Doom's Day, but I do find the definition of progress to be a multi-faceted, direct correlation to humanity, or as this book challenges, inversely related. As Le Corbusier once stated in Towards a New Architecture, "[Progress is] the study of minute points pushed to its limits." I think that we forget that limits do exist. On a sustainability level, we seem to forget that growth is bound to a carrying capacity which is only a constant. We exceed limits in population, in wealth, in energy consumption, and we are doing so blindly because we believe we are progressing. This is the first that I heard the term "progress traps" (which I think Wright may have coined himself), and I believe we seem to fall under the impression that distilling or expanding our limitations is an ultimate form of progress, when in fact, its lack in sustainability will only push us back. If you have the time, it's a pretty quick and enlightening read. If you are still on the fence with the concepts discussed in the book, I recommend finding it at a local library before committing to buy. For me, I recommend it.
Also, if you are interested, there is a documentary based on this book called "Surviving Progress" (2011). I prefer the book so much more, but the documentary wasn't that bad.
