This video is about explaining the difference in shift phase RPM and top speed rpm during the clutch phase of a CVT clutch like on any CVT vehicle such as a Polaris, Can Am and Yamaha

I like this guy so far. Seems like the guy that built my race car no bullshit.
Thanks for another common sense approach to a problem. A good explanation of how a clutch works and possible problems.
20 years ago when I drag race snowmobiles we gained top speed for the radar runs by changing the primary to a overdrive shieve which would push the belt out further and allow us to run a lower gear ratio for the hole shot and without losing top speed or even Gear Up and add the overdrive sheet if you had enough horsepower to pull the extra mile per hour
No such sheave for these and you can only run the belt in the secondary so far and most of these are at that limit already
Wow 9000 belts in 13 months, Congratulations Todd!!
On edit: Fantastic content and video!!
Thanks!!!
As I just picked up a newer ATV I was actually wondering if an overdrive she would help gain top miles per hour by two or three miles per hour?
how does high/low gear work in my Teryx for example? Is it a physical different output on the engine, or is it related to the CVT?
It is internal of the transmission, just like your car or truck Different set of gears
I like ur videos
Thank you
Great video Todd. With this information in mind, how does the secondary setup (spring/helix) affect engine rpm? When do we know when too much helix or too light of a spring is being used?
Hard for me to answer that, we use stock stuff or Dalton kits and that is determined.
Does the top speed have to do with the springs and helix or is it all in the gearing in the transmission?
Answered in this video.
Great vid. Can you explain the effect of increasing power by adding a turbo kit on the CVT and what clutching changes does it require on a stock 2019 Wildcat xx? Stock 30” tires and possibly paddle tires for sand dunes. Basically going from 130 to 190HP.
Probably won’t be a video not our area. However due added power you must put heavier weights in primary to load clutch up more. We on deal in stock engines.
@@Hunterworks thanks for the explanation. Now I understand that with added power, the clutch engagement will be snappy. So, it will need heavier weights to put it back to to where it should be.
@@Eastern_SA not really just need the clutch to close faster to put a load on the engine. Pretty standard cvt practice. Lots of info on the web. Just not area we are in.
My shift phase is perfect 8500 but after a while ramps up to 9000. Is that normal running stage 4
What’s a stage 4?
Change my secondary clutch on 570 2015 Polaris to spring clutch your belt seems great what do I check after short run time clutch looks like 800 had them set spring running stock no modification
Robert, I am sorry I do not understand what you are asking send me an email todd@hunterworks.com
Great explanation. Do you consider CF moto an okay brand? You will eventually care kits and belts for this machine brand?
Unfortunately we won't be doing any CF moto parts, sorry. On the brand, I have no experience, sorry.
CFMOTO use to be considered a newer brand but they've been in business for over 30 years and are on the heals of the bigger more popular brands , myself I've owned 3 now and would definitely consider another one in near future , for the price paid and what all you get , it's hard to beat a CFMOTO.. Comes with standard options that the bigger brands don't.. The CFMOTOs all use CVTECH Canadian Clutches which are one of the best on the market and easiest to tune , The secondary from factory has 12 different settings alone , then you have oevr a Dozen of Primary spring options.. I know of guys with well over 10,000 miles on thei lr clutches with 0 issues , several over 20,000 miles on their machines. Cfmoto is definitely here to stay and is growing fast
How do I drop the rpms in mid range on a 21 polaris general xp4 with 32" tires? Cruising 25 mph in high gear at 6000 rpms right now.
That is low to me.
I have a question about my primary clutch on a side by side I own. For some reason when it's in park it will engage and do what is supposed to but once I put it in low, high, or reverse it doesn't want to engage at all.
Also the machine won't start moving until about 2500 rpm and at around 5000 rpm it will finally start to engage properly
@@jonathanclark4839 Watch our how to troubleshoot a primary clutch video and it will help you find it
Is there away to drop my rpm when I'm top speeding IE 70 mph with a cfmoto zforce sport 1000 I have 18g weights and a spring that dropped my pull away rpm to 1800 to 2000
TopSpeed RPM is not controlled by clutching I’m not sure what style of clutches in that one but you would have to overdrive the belt like we do on a Yamaha rhino and a Polaris it’s not possible
So your saying the reason i cannot reach my max rpm at wot is i dont have enough power ? Yet i have a factory gear reduction cause its utility model (more power ) yet normal sportsman 570 can go to 7400 rpms im high speed
Most likely that is what I am saying but I do not know what vehicle you have however low speed low rpm equals low power for some reason no matter the vehicle.
Great vid! Just wanted to point out there's a P missing in your video's title.
Fixed and thanks
@@Hunterworks what if I put a clutch for 32 inch tires but run 27 inch tires with it would I lower rpms? and would it result in a lower top speed?
@@crazyspeakerpro9584 no really high rpm and lower stop speed most likely hit limiter
@@Hunterworks ah right on... would that be the same on a quad too?
@@crazyspeakerpro9584 does not matter what the vehicle is, lighter weights makes shift phase rpm go up
Does the secondary clutch spin In park and neutral? I am new to a 1000xp and I can here something in the clutch just sitting there idling through the air tube up to the vent on the bed? I had a 900 and it didnt have the vent so I never heard it
It is not supposed to be spinning in either
@@Hunterworks well I hear something in there through the vent not sure what it is I have not pulled the cover and checked yet.
ICU81 2 best to take cover off
How can I shim my secondary clutch on my 21 Polaris razor XP four
if not a turbo, you don't you use our tool
Send me the link for the Tool I need and thank you for the help

Just got a new 2021 rzr xp1000 4 seater before it does about 68 now I can't get to go faster then 50 55 mph right at 55 the rims shoot to 9000 you have any ideas on this thanks
Yes, sounds like spider nut and spider in primary backed off, but since new take to dealer
Any chance you ever figure that out I am having the exact problem
Does the Dalton Helix reduce engine braking when trail riding? I do a lot of mixed trail riding and then I'm Full Throttle when I'm able to be I like being able to beat the others riding with me. I just put 30s on my Razor and I've noticed a power loss.
What year and model?
@@Hunterworks its a 2018 900s rzr. I have your round rollers in it and I stage 1 ECU tune. I'm running your belt as well.
@@codycrabtree3684 yes it will reduce the engagement harshness for sure, but you still have it due to the one way bearing in primary
@@Hunterworks will it still hold back going over hills and such?
@@Hunterworks ill order a clutch kit from you tomorrow
How do you change the stall rpm. I have a rig that doesn't engage until 3700 rpm.
I want to bring it back down to like 1500-1700 rpm. I'm planning on running 32" tires and this is a boosted RZR XP 1000. Sitting at 300whp on C16
It sounds like you have some kind of primary clutch issue a physical issue or a clutch kit that matches that horsepower that does nothing else but allow you to put your foot to the floor
@Hunterworks Inc. it has a sand something clutch kit made for the dunes. I just got the RZR. I'm trying to get my engagement back to stock so we can run slow Technical stuff too
@Hunterworks Inc. what are some things to check for dropping down engagement RPM to desired rpm on performance clutch. Do I need all new clutching?
@@Hunterworks says custom clutching for the sand only 3700 rpm stall and a STM secondary clutch
@@joebidden4914 That would require you to call them for a set up with those clutches, would have to have stock clutches for me to be of much help
Have you dealt with John Deere gators much in the past?
No sir, sorry
How do i get a lower shift phase
You can do it with an adjustable clutch kit like the Dalton we sell but as a general rule you don’t wanna lower shift phase unless you’re only a slow driver and need belt grip
How can I lower my RPMs at 65 mph, I use my RZR almost all Highway / freeway driving... Can A clutch kit change this? A larger Clutch to increase top end... I want higher top end and lower RPMS...
You can't with clutching, your clutch is fully shifted out, only way is higher gears in tranny but that would be a huge mistake to me.
@@Hunterworks So whats largest tire I can Put on it to change gear ratio? 32-36? I have all stock arms.
@@payme0 What is "it"? What kind of riding?
@@Hunterworks all terrain tire, mainly on road and on some hardpack and sand
@@payme0 What is it meaning what is the vehicle?
