Tried to find link to buy your clutch kit and not finding on your store. Are you still selling it?
Yes we are. Here is a link rngperformance.net/shop-parts-accessories/ols/categories/cfmoto-clutch-kits
@@R.N.GPerformance I have a 2022 cf moto zforce 800ex. It jolts like crazy when taking off. If I install your clutch kit, will it take that away completly?
I don't understand why CF Moto can't just make a great clutch set up from the factory? Isn't that what engineers are for?
I agree there. Yes it is.
Can't make a one clutch fits all,so the factory tries to make everyone happy, the clutch kit user is the person that knows what where and when the ride needs power torque or rmp hp, no one will ever be totally happy with a factory clutch, unless you are a casual rider and don't push the machine hard
We were test driving utvs, did can-am defender, polaris ranger, both 6 seaters. Also tested a cf moto uforce 2 seater that the belts were squealing and was very noisy in comparison. The dealer just said, "They're all like that." Assuming he meant the moto's? The other one we test drove weren't. But then, the engine and transmission was a full row of seats back further. Would it make that much difference?
The belt shouldn’t have been squealing.
Question, my machine has 19 miles. The grease isn’t catching. The belt looks ok, but I have to press the gas all the way for it to even move, any idea what that could be?
Man thank you so much for that video . I have a 2022 CFMOTO 800 XC and it has had the jerky forward or reverse since new on throttle . Haven't had first service yet but was going to ask about it and you thank the Lord answered my question . Thank you so much . That eases my mind . Your awsome and you done a great job explaining it .
Thank you happy I could help.
Hi .. Something completely unrelated. Is it hard to take the doors off of a G2 ZFORCE 800 trail. Can you send me some directions or make a video . Thanks
Dude, you are CFmoto genius. I learned a lot from your videos. I will resort to your amazon store for any future parts need.
Thank you 🙏 also check out our website www.rngperformance.net
Hello RNG, thanks for your tutorial videos, i research those a lot for my 550. I am in Germany and my official vendors has no idea about how to fix or tune CFmotos,. Apart from the mere stock CF stuff, there is extremally little or anything to tune. Also, while i have been asking the supplier since the beginning why my CF does not go on Low gear (have to haul alot and work on the farm so that low gear is key for me), i wander if you would know any particulars on why its not getting into Low gear, or if the gear is actually in, it slides out in midway (also i cant put it in park otherwise it wont release of Park and cant start or move)? I wish i could order from you and have things shipped from your website (but it would be too dear and customs would snatch it up) and just do it all myself- but again there isnt such a support in Germany yet, as far as i know, so I have to rely on the official vendors, who have literally no clue....
Jerkines is mostly because belt is burned or its under 33mm. Also youre missing alot of things that cause this damage to belt or even CVT itself. You should mention them if you want make videos about it.
Have less than 1600 miles on our uforce 1000 and its already jerky. The belt was inspected and looks new. Issue is not just because of worn belts.
I have a 2021 uforce 1000 that just won’t start. Last time I drove it it was just fine. Unfortunately let her sit for a week before I tried to start her again. She cranks but no start. Any ideas much appreciated.
its easy the jerky is the person behind the throttle just get out your grinder and grind your belt down on each side until you see cords fly off then cut groves in top of the belt then turn it inside out flip it upside down make sure to sand the primary n secondary surfaces with 80 grit sand paper until ya see deep scratches then hang on cause now your atv will haul ass lol
😂 😂.
Mate do you have videos regarding on one way bearing on my primary clutch ? Hard to hift while on h,l and reverse but when the engine is off its smooth to shift? Tnx

Red Nick, you do a great job on your videos, Thanks, My question is: going over the top of the Clutch is a shielded piece of plastic, which seem to go into the back of the motor, and it has a clean out on the bottom. What is it for? Breathing for the CVT? 2022 CFmots Zforce 800 ex. THANKS and keep up the great work.
Yes. And it’s for water to drain it if it gets in there. Thank you 🙏
Wife and I just picked up a '22 Cforce 800 XC. Great machine and great explanation on how these clutches work. I possibly see upgrading the primary in the near future to smooth it out. Do you know how modifications affect the warranty? We have a 5 year full coverage warranty. Thank you!
Our primary kit for the clutch won’t effect the warranty. It will be nice and smooth with even more power for sure. Some mods will like bigger tires. Lift kits exhausts etc
I finally got time to install my clutch kit from you( primary, secondary spring, and helix). So the "clanging" sound at idle from the primary is normal? I removed the primary probably 5 or six times. The sound goes away when the rpms increase. It frustrated me. Put everything back together, took it for a spin and it was very smooth engagement. That "clanging" really gets me. Your videos are great!!!
Clanging is normal that’s the 3 slides on the cam plate.
@R.N.GPerformance thanks for the reply. Never had the covers off before. It seems more of a pinging, not a clanging sound. It's not as noticeable with them on. Your videos are very helpful and informative!!
Hey! Someone sent me your link. Lots of good stuff on here. What is that tool you used to loosen the belt? Also was it clockwise or counter?
The tool is just a m6x1.0 bolt 3 inch long threaded all the way it’s regular thread. The primary clutch is reverse thread. The secondary is regular thread. Thank you 🙏
That knocking was driving me crazy before I found out what it was.
Right
I just bought new 800XC, and I can hear the little clunk sound sometimes when slowly applying throttle and taking off, could it be those plate pins as in the video?
@@edgarascernikas2238 hm I’m not too sure about that. The newer models might be different too.
I hate I bought a Cfmoto 1000. They tricked me with the price. Had I know it runs and jerks like hell.
All you need is our primary clutch kit it will be a nice smooth machine. We have video showing this. th-cam.com/users/shortsrMjt5AwUhI8?si=OYYS84jukoU7NaJV
I really appreciate that u don't put all those commercials in in videos 👍👍👍
Thank you 🙏 we definitely try not to do that stuff. That’s why it’s important to help support us in other ways.
I just went to be able to start rolling at a lower rpm. I have 2 - 600 touring cforce completely stock everything and I have to rev it so high just to get moving. Anyone have a suggestion in what clutch I should purchase?
You need our primary clutch kit it will take care of that www.rngperformance.net
I got a new 2023 uforce 800 I owed a 2017 uforce 800 before and it had engine braking my new one don’t seem to be working do you know what could be the issue
My primary kit that will help allot. rngperformance.net/shop-parts-accessories/ols/products/cfmoto-cforce-1000-stage-1-clutch-kit
Thanks for the info, very helpful. Just got my new UForce 1000 and noticed it’s a little jerky when I step on the pedal. I’ll wait to see how it goes until after it’s broken in.
It will continue to be jerky. The problem is not the clutch. A clutch kit will make the initial belt engagement better but not much. The problem is the the throttle sensitivity. Cracking the throttle even one millimeter, the engine ramps to fast. The fix will be softening the first 1/2" or so of pedal movement. You don't need to go from idle RPM to the machine jumping in 1 millimeter of pedal movement. Once the belt is engaged, the throttle needs to ease into the RPM. The UFORCE 1000 does not. It's a real shame because the machine is pretty dang nice otherwise.
@@philburke1902 Thanks for the advice. What state do you live in? I’m in PA, if your not to far I would consider having you work on my unit…
Thanks forc sharing your knowledge. This is interesting stuff.
Ordered my kit from you couple weeks ago hopefully it does just what your saying when I get it 👍👍👍
It won’t disappoint that’s for sure buddy.
Hi RN quick question, my 22 UForce has about 900 miles and I’ve been running one of your basic clutch kits for 4-5 months. I recently started getting a grinding sound in low gear when I’m slowing down to a stop. Never in high gear but it is intermittent in low. It sounds like the gear (or clutch?) is not fully engaged, but never happens on take off. Any ideas what’s making the sound? Is it the primary bearing? Thanks!
Shifter linkage buddy. Low gear isn’t locked all the way in. Or pinion is going out. See my newest video we blew a rear differential.
@@R.N.GPerformance thank you! I will check the linkage. Would it be the Front or rear pinion? I can check that too. 👍
RNG, why is the Yamaha CVT rated the best in the industry and they even back it up with a 10 year belt warranty. Why are they so indestructible?
I have no idea. I think they are just brave. 😂. They may also use a wet clutch too that takes the beating instead of the belt. Like our zforce 800s
This was a awesome indepth vid, thank you
Your welcome 🙏
I have a 2022 CFmoto 800 EX With around 500 miles on it that around 5 miles per hour has this jerkiness and rough sound but it sounds like this could be the issue...
Definitely I agree.
Hey RNG my 2023 uforce 1000 has almost 2000 miles on it and it's made that rattle cling noise since I bought only does it at idle what could I do to stop it called the dealer and they gave me some run around that they hey dirt in them that's why it's making that noise I bought it brand new and it made that noise just trynna get it fixed the only problem I've had with mine
That noise is normal for these clutches. However if that noise gets really loud you will want to replace your sliders here. rngperformance.net/shop-parts-accessories/ols/products/cfmoto-cam-slider-replaces-oem-number-0jya-051004-10000-fits-most-models
@R.N.GPerformance OK thank you!!
Good morning. I have the Ultimax belt currently on the machine and the CF Moto belt in the box as backup.
Morning sir.
Fabulous thank you!
$369 for a clutch kit , it doesn't come with a new one way bearing or a new belt ..... than they still want you to buy specialty tools..... i should have just bought a honda
Is it possible to replace the belt without the tool to spread the secondary? Replacing belts on snowmobiles no tool is needed. You can simply spread the secondary apart to gain enough slack to slip the belt off.
No. You need this tool. rngperformance.net/shop-parts-accessories/ols/products/cfmoto-oem-secondary-spreader-tool
Mine is smooth.
Is there torque specs for the clutches?
Hello Guys ,I have an issue with a CFmoto 625 from 2022 4500 Km on it . Will start but will go high in revs around 2500-3000 then comes slowly down and stays or slowly fluctuate . When driving it will not go more them 40 Km ( in hight ) , from there on the engine is stalling , like it does not have power to go forward. If I start the machine in neutral and rev it , between 4000-5000 it is like is folding something the engine back and will hesitate to smoothly rev after passed the 5000 barrier will rev till max.
I have checked the bet, one way bearings weight etc there is all fine , as it does the same when those are off. Has already new spark, spark lead . New filter . No error on dashboard.
Does anyone came across this and can give me some advise ? Thanks
In trying to replace the one way clutch bearing on my cforce 500, the bearing will slide over the shaft only to where the locks touch the shaft and won't go any farther. I already trashed one bearing by trying to lightly tapping it the rest of the way onto the shaft
SO HOW DO I GET THIS BEARING TO GO ALL THE WAY ON?
Looking at a CF Moto for snow plowing 99% of time, but after watching your videos, there seems to be issues with the machines. Looking at a cforce 600 or 800..can you give me your opinion as to this?
If I put my CF Moto into low gear it pops out sometimes? Can you tell me what this is a symptom of?
Shifter adjustment
@R.N.GPerformance wasn't sure. I just got this 2013 uforce 600 rancher. I'm trying to do all the maintenence. The belt scares me. It looks like I have to pull the gas tank to even check it. Lol. I've got it all ripped apart already, just not sure what the best approach is. I download the manual but there isn't anything in there about it.
Alison Junction
Do you have any clutch kits for the 800xc that increase the low end power, if so how much HP gain does it produce?
Hello I have a 2020 cforce 600 it started perfect for months now lately it don't want to start have to give it some gas for it to start then I have to hold the throttle for about a minute before it'll idle. Any help? No check engine light or anything. One way bearing was gone didn't know if that would make it hard to start?
Thank you so much for this information. As soon as you pointed out the one way bearing I knew that was my issue. I have been weeding through BS trying to get a better understanding of what is going on in there before I tear it down. It's been getting hard to shift over the last snow plowing season, but now I have to shut it off to shift it. The shifter wont move with the engine running.
I wish you can call me .I like to talk to you about mine. It's new and only has 50 miles on it
Give me a call tomorrow 3308060728
Thank you I will
Excellent explanation.
Wow CFMoto must have heard us out about the jerkiness cause my 2022 CForce Touring has no jerkiness straight out of the box from the factory. Great video!
I got a 2022 uforce 600 and mines jerky.
@@buffdaddy2032 you may wanna try a clutch kit. That will take care of the jerkiness and give you a little more power. Contact RNG Performance. I guess I just don’t pay any attention to the jerkiness. It really doesn’t bother me.
My 2024 400cc touring is extremely smooth.
Do you have your microphone in your throat?
Maybe
Labor hours clutch kit remove and install
Love your stuff man. The only thing that makes me lose confidence with you is the Mac Tools hoodie 😉 lol
Help slight sqeek when setting off then noise goes like rubber on metal ay ideas belt looks fine
Hey I’ve been watching your videos learning all kinds thanks a lot man. I swamped my 2022 cforce 600. I did a cpl of oil flushes cleaned air box got new air filter and going to take the belt off and clean the clutch out tmr lol wondering if u should take spark plug out and clean that or not lol I’m on your videos steady hahah appreciate the help!! 👍
Hi,
my primary doesnt spin when motor is startet - just when i push the gas
Nice video
My 2019 CFmoto Cforce 500s (75hours) was stolen and when it was found it wouldnt drive-found the remnants of the belt in the clutch and a weird tapping noise-cleaned it up and reinstalled with new belt but still makes weird nosie and when I put in gear the engine dies-Im guessing both primary/secondary clutches are shot? I think the thief rode the ATV fast in low gear? Is there anything I need to check? Im scared something internally is bad…
I dont mind paying you for your time/information definitely not here to take advantage of your knowledge-Im just on the fence on buying $600 worth of parts if it could be something else
I have a UFORCE 600 and Im having trouble finding that particular clutch kit on your Amazon page. Can you help steer me in the right direction.
You can get our kits here www.rngperformance.net
So I have replaced my one-way bearing it's on counter clockwise and cleaned off with alcohol to be sure that grease is not my issue but still I have my secondary spining in Natural and park. If I go back into high and back to park it stops for a few the starts moving again. Sorry to ask you this but I feel your my only hope! Thx 🙏 my friend
Give me a call tomorrow 3308060728
I just got a new cforce 800xc and just done the first gear and oil change on it. After a 2 or 3 hrs of riding I have trouble getting it to shift into (park) I have to rock it or backup to get it to go into park. My question is why is it doing that and would a upgrade clutch fix it?
Clutch won’t fix that but it will make it nice and smooth and add more power. A shifter cable adjustment may fix it tho
Can you lower engagement? Like softening the secondary spring setting?
We can with a primary clutch kit www.rngperformance.net
My CFMOTO does have a jerky start when cold. Once it warms up - everything is ok and it starts smoothly. What could be the issue?
Nothing. Sounds good to me.
Whats the weight and dimensions for cf625 of clutch kit 1 spring and weight?
Message me www.rngperformance.net
I have a cf moto 2023 800 ex, around 2-8 km an hour I jerk and it doesn’t sound so good… do you believe this Could be my issue?
It’s very very possible
Are gates belts any good?
I’m not a fan of them. Dayco, Ultimax, OEM are my favorites
Great video great narration lots of info and straight to the point thank you
Your welcome 🙏
What if it's brand new right off the showroom floor and I'm having problems shifting it
Take it back.
Great Video my Friend
Thank you 😊
🤣 I got 100km out of my OEM belt paid $317 for a new cf Moto belt and got 25km out of it and it's screwed again. Regret not getting a Suzuki king quad. Nevery had a problem with my old king quad
Have you gotten a clutch kit? I recommend only oem belts we sell them far cheaper. I would also recommend our clutch kits. We are seeing awesome belt life in our rigs

@@R.N.GPerformance no clutch kit on it yet only had the bike 2 weeks really frustrated that the belt has gone out twice on a $22k bike I just bought 2 weeks ago
Hello, Any idea why I get a high pitched ringing sound from the clutch, at about 30mph on my Zforce 800? Thanks.
That’s probably the rear differential your hearing.
I have a cf moto 2020 600 do to muchs noise but son like the engine like metal with metal
Ouch.
Hi Steve, can you please send me your email address! I want to send you a video with my Atv problem, I need your opinion. It has a strange sound when reducing the power (Cfmoto 500-2 A). Thank you!
If I have a uforce 1000 do you think it would be okay to do 30 inch tires and a 2 inch lift or should I just do 30 inch tires or maybe 28 inch tires and a 2 inch lift. I mainly ride a lake bottom it’s sandy in some spots and muddy and rocky. It’s road a lot so the mud is real thick and deep. Just wanted a opinion
You can do 30s and a lift. I do recommend 1.5 spacers in front and 2inch in rear. I do sell this stuff on my website. Www.rngperformance.net
Would you know why the clutch weights come out of position.
? Not sure
Great info! Mine has a "rattle" when I rev it, would that be the plate on the primary? I assumed it was the weights in the primary. Mine has 400 miles and its rattled for a bit now. Just cleaned the CVT area and replaced the belt, still rattles
Rattle is normal on these clutches
@@R.N.GPerformance I figured.. I did recently do a valve check just to make sure it wasent the valves lol
So I have a 2018 cfmoto zforce 800 trail. Recently I've been having an issue. I got a bad smell and let off the accelerator then it just locked up. I was able to ride it home then drove around and it drove fine. Then today I got the smell and seemed like it was stopping pretty quick. Any suggestions?
Check your belt
@R.N.GPerformance this is my first utv so I'm new to this scene
So the belt is all good. Problem was I was driving and I Smelled and possibly heard something weird so I let off the throttle and atleast one brake locked up I believe. Cuz I got the whole tire squeal letting me know it wasn't turning. So could maybe something with the brakes? But idk what would cause it
Is it normal to have a small pin hole in a primary clutch outer sheave? On the belt rining side? Putting a clutch kit on a friends bike an I noticed it.
Yeah. That’s from the casting
@R.N.GPerformance thanks appreciate the reply 👍🏼
I was going to buy a c f moto side by side. But no way. How in the heck u change a belt on the trail. No way
? Changing this belt would take 5 mins.
On quad. Do a sxs. On trail.
Tried to find the clutch on Amazon. Could you help me out. Not sure which one? I did look under RNG. Thanks

What are you looking for?
@@R.N.GPerformance my bad. The clutch system you did the video on. I have a 2022 c.f. moto 1000 and ran tracks this winter in Montana and it jerks starting out in high gear. Really annoying now I have the wheels on.
I heard it was common for when you put these into gear and then put them back in the neutral you kind of hear a little winding sound does that sound normal to you
Yes

I have purchased 4 CFMOTO machines and have zero regrets
I guys tnx for all your feedbacks I got my unit, a month ago and I love it!
Plenty of power and it feels very solid, looking foward for hunting season!!!
CFMOTO is not good.
It’s not? Did I waste my money on 8 of them?

Do your clutch kits void factory warranty
No they don’t.
Ok thanks
Do you lose top speed with the clutch kit
Depends on the kit you get. Some you do some you don’t. Just the primary kit you don’t lose much if any depending on machine tire size etc. you gain allot more power to the ground.
Save it up my lunch money for a clutch kit can't wait to ride with you guys in the Spring
Heck yes 🙌 will be fun.
great content.... i also did the reset on my oxygen sensor and noe my UF 1000 cranks like a charm and purr sooner and quieter.

Heck yeah good deal.
Best to buy a Honda with a real transmission, no belts, and never have to deal with belt slippage, breakage or weights and springs. 🏆🏆🏆
No thanks. Honda and transmission plus reliable don’t even go In the same sentence 😂
@@R.N.GPerformance I stand by your assessment. Hondas last real transmissions were made in 1997 on the Japanese built accord! 😁
I had a Pioneer 700 for seven years which I just sold for a 2023 Yamaha wolverine x2. Reason why I didn't go Honda again was lack of innovation and improvements in their sxs.
Not true if you get the hondamatic, any water trashes it and your out 2k for another, the foot shift is a different story, but the auto is not as good
I just sold my P5 with 5.9 " of suspension and a single cylinder for an 800 ex with 64 hp and 10.5" of stock suspension. Only about $2k difference and 3 years/3 k miles newer!
I have a 2017 800 EX identical to yours it has a real bad dry bearing sound the whole time you're driving I had the engine rebuilt Guy guy charge me 2800 to rebuild it has a real nasty dry bearing sound super smooth kind of hard to get in park the whole time you're driving it it sounds like a real dry bearing what could that be redneck
Could be wet clutch.
