- Removal of speed collar on all kfx 90 models. I'VE BEEN TOLD THE 50CCS HAVE THEM AS WELL WITH THE SAME PROCESS....ALSO THE SUZUKI LT-Z50 AND LT-Z90 HAVE THEM AS WELL AND IT'S THE SAME PROCESS. THANKS FOR WATCHING!
I wish every instructional video on UA-cam got to the point as quick as yours does. I could care less about the slightly shaky video you got to the point and showed exactly what you need to do and didn't waste a lot of time doing it. I'd rather watch a video like yours that's slightly shaky than the ones that are perfect video but take 20 minutes to give you two minutes worth of information. Nice video very informative.

i cant believe people still giving you a dislike is the most explanatory video thanks for doing it
Very clear and concise instructions. That one short bolt is a GOLD nugget of information. Most people overlook things like that.
Not all heros wear capes.. 😅 awesome video. Right to it. I like it..
I can vouch for this mod working on 2010 and 2011 Arctic Cat (utility) 90's. Two additional tips: (1) there are a couple of spacers (small bushings) sitting in the bolt holes between the outer case and the main block. Don't lose 'em. (2) One of the bolts was shorter than the others, and you need to make sure it goes back in the correct hole.
The difference was amazing! Thanks!
Those are dowels.. your right dont lose them. But ok if you do. They just align the case to the block. If anyone loses any just put all the bolt in hand tight check the perimeter and then torque down and it will be fine
just pulled the collar on my son's 22 kfx90 today!
Many thanks and great video! After watching, I removed the collar on my 2020 KFX 50. The process was essentially the same. I used my Ridgid cordless impact driver for that 17mm nut. For those of you who are trying to do it by hand, it won't work unless using the speed and torque of power/ impact. Now my son is having more fun than ever! ITS SIGNIFICANTLY FASTER!
What do I tighten that bolt to?
Great video, your the man. Took me 10 min to get it done.
This was the best UA-cam video i've ever seen. Thanks bro.
I watched a few other videos and your video is by far the best. You are the only one to drop the belt down in the secondary pulley to get enough slack to reassemble 👍🏻
Wow! So easy to follow your video!! Thank you for sharing tools needed ahead of time! We just did on our 2014 today. Just paused as we watched, now little man is ripping around twice as fast!
Youre welcome. Just what I wanted to hear!
Nice job 👍🏻 I like how you gained slack by dropping the belt down in the secondary. Next time my 10 year old grandson comes over I will show him your video and let him do the work
Thank you… finally found a short easy video without added nonsense
We found this video to be very helpful. Thankfully everything went off with a hitch unlike some others that can't get that bolt off
THANKS JUST REBUILT A 2017 YESTERDAY FRONT AND REAR CLUTCHES NOW IMA TAKE IT BACK APART AND REMOVE THIS COLLAR THANKS TO YOUR VIDEO! KEEP MAKING CONTENT MAN MUCH APPRECAITED
Thank you. I just did a 2020 KFX 50, seemed the same except no short bolt, all 8mm were the same and did not need to do anything with the kickstart either.
Im about to attempt it today. I also have a 2020 kfx 50, im glad to see that this will work. I saw a few comments where they had trouble with a 2015
How much does i help on a 50cc
@@johndoe-tf7tq it increases top speed... it just let's the belt ride higher up on the clutch, basically changing the ratio, like the CV belt version of shifting into a higher gear
Just moved to this model off of a two stroke. My kid races harescrambles and this will definitely help. Thanks for the video. Hopefully this will give him the speed he misses from his two stroke quad.
Do these have a safety switch on brake lever that has to be pulled in for it to fire?
Dude, great video! No bs. Fast, to the point. Thank you
Great video brother. Simple and to the point. Thank you!
I took all my time finding a bid yours is the beat
Thank you thank you thank you for this video my son has exactly the same quad this vedeo helped more than i can say thank you again
Great advise, it’s very helpful unlike the other videos. And the quality is fine😀
Although I would like to see it drive
Exactly what I was looking for! Thank You!
Great video! Thank you for sharing bud!
Mate thank you so much.... What a great video... My kids will love the new speed.... Keep up the great work and thanks again 👍
Jd0ggy86 ...no problem. anytime I can help I'm all for it.
One of the best videos for this... thanks!
Hi! I tightened 17mm nut back in w electric impact gun, but nut fell off after a day of riding.
Any specific reason that may be?
sick my ltz 90 is great but knew there was somthing holding it back thanks for the video!!
How fast will it go,without the speed collar
thanks a lot , your video helped me with my 2016 suzuki 90 👍🌷
bosaleh74 ...ahhh...so the z90s have them too! that's good to know. thanks for the info.
your welcome , and thanks
bosaleh74 .....you were absolutely 100% right. I just bought my son a 2017 suzuki lt-z90 and it is done in the same process as the kfx.... so similar in fact I was going to make another video but if you follow my instructions on this video it should be just as easy. Give or take a few different fasteners.
that's good , congratulations 👍
by the way , all the ATVs that I know are made in Taiwan, kawasaki, yamaha and suzuki , you can see the same DNA when you work with them
So what is the best , the z90 or kfx90☺️ ?
you_salty_bro?
bosaleh74 ...., yep. Kymco is making Kawasaki ATVs anything under 125 CC... I bought the Suzuki thinking it was going to be Japanese made but apparently somebody in Taiwan is making that as well. the suzuki is too new right now to get into the throttle to see what I like more but I have a feeling I like the Suzuki better even though I'm a little kawi fan
Thanks for taking the time to make this video!
Just what I was looking for, thanks!
What if the bold is stuck plus I have I kymco 90 mongoose
Great Vid!!! 👍 thx!
How much faster is it?
How much mph you get by doing this? Wonder if a 2020 has that collar
So if i change the weight of the rollers will it give me some acceleration/top speed? And if i change the spring tension in the clutch will it change the engagement feel of the bike? How bout changing the contrast spring to change cvt transition between low/high gear ?
Would you recommend this as a first gas powered 4 wheeler and later remove the limiter or start with a 50?
Perfect forst timer. You can adjust the throttle response on the handle bars.
My impact won't loosen the 17mm bolt.. what else should I try ?
Could this same procedure work on a 2020 kymco mxu270?
Thanks much your video was very helpful. However I have a kimko 50 quad that only idles but don't respond it full throttle plus it started running in reverse any reason y it runs in reverse and how to fix it. Any help would be greatly appreciated thanks
Thanks brother. I just bought my son the new 2017 kfx 90 and its way to slow. I took off the silencer and it sounds nice. But needs more power
how did you take the silencer off?
Upgrades that will get your kfx 50 or 90cc way faster...
After hrs of research what I did to my sons 2015 kfx 50cc ,top speed 23mph ,and it picks up speed quick
1.removed the collar
2.performance coil and cdi total cost 45 dollars for both cdi needs rewiring but it's super easy make sure it's (DC CDI)
3.UNI air filter drill holes for better air flow 16 dollars
4. 5gram performance rollers 16 dollars
Last upgrade the most expensive is
5. Pro circuit exhaust t5 they cost new 260 dollars or get lucky on eBay like I did 90 dollars
Cheap easy and end result fast 50cc I have videos thanks
Where are your videos? Could you give details (part #s, and such)?
Chelsey estrada where can I check your videos?
Thx for this. Simple to the point.
Is it possible to over tighten the front 17 mil bolt?
How do I keep the flywheel from spinning when removing the 17mm nut?
Coach Langley did u figure this out
I had to use an impact wrench
Got to use a impact gun
Great Vid!
Great video !! Finally someone that did one worth a damn ! hey would you recommend replacing the belt while your in there ? Mine is a 2007 KFX50 with maybe 30 hours on it.
Doug T ...it wouldn't hurt. but it's not necessary unless you see fraying or chunks missing. I'd just run with it bro.!
great video thank you!
That's how you make a fn video. Preciate it
Excellent video
Thanks man. Just did this to my sons 2020 kfx50 noticeable difference.
I wanna buy one for my son but 8mph just doesn’t seem worth the money, how much faster did it go after the collar was removed?
how faster did it make it
I did this on my sons 2020 kfx90 but when he lets off throttle it makes a terrible slapping noise and you can feel it. I’ve taken it apart and put it back together 3 times and still same result. Any ideas on what is causing this?
does it work with all atv?
Good video!! Do you know if the can am Ds90x has the same collar?
Hey I was wondering how to tighten the belt on the clutch
just did this to my sons 50.....thanks
So happy to see this video
Great video! I'm going to try that! Any advise on a hard start? Motor turns but does not run? Anything I can do?
check spark plug first. sounds like the carb is dirty. remove that and give it a once over
you are a dead set legend mate!! cheeers!
thanks bro! glad I could help.
Thanks for the video. It's a lot of help.
Great video!!! What’s the rough speed difference with and without the collar?? Thanks brotha!
8mph with speed collar, 15mph with speed collar removed
2010 kfx 50 owners manual says it does have a reduction speed collar that can be removed by the dealer.
if thats the case then im sure it does. if so it would be the same process as the 90. if the procedure is different then you might have to remove the whole clutch boss and replace it with a boss thats diameter is smaller.
this is what the boss is..

Will the idle go higher if you remove the collar speed?
Do you know if the Raptor 90s came with that.
Thanks for the info helps a lot.
How much faster does doing this make it? Is it actually worth doing.
About double.. goes from 15mph to around 35+- depending on weight of the person riding. DEFINITELY worth doing.
Awesome thanks my son is now 4 and it's starting to get a bit to slow for him theres a few videos of him riding on his channel ATVchild if you're interested in checking it out .
I'm guessing it won't over rev the engine or anything like that right?
No. It will not over revv... the whole family will enjoy it. I kno I did more than my son did! Lol
Should we drain the oil?
No. No need.
@@whiteoprahOG is it serious?
Does it work with all the ATV
Is this a way to make the quad faster then I's normal speed. ?
Does the kfx 90 have different transmission and engine oil ?
Great vid, Thanks!
My quad is leaking oil from behind the clutch. Any ideas how to fix it?
Heck yeah, thanks brother!
it worked it worked it worked thank you so much!!!!
some videos say to cut a wire under the seat. do u have to do anything other than remove the collar like u did?
jeff phillips ...nope. the wire cut is a rev limiter wire...the atv is build for a 12 year old...so the real question is how long to you want him to live? if a 90cc for a child is not fast enough just upgrade him to a kfx700. it's full auto as well. :)
thanks for making this video
I've been working on my 2007 kfx 90 for days and we even bought the impact driver for this but the yellow bolt will not budge please help
Maximus_Overdrive _ ...might have to bind the clutches and use a ratchet and breaker bar
I can't get the clutch off when I try to undo the nut the clutch spins
need an impact....or a wedge of some sort to bind the clutch
Yea I had this problem too
I’m a little late on finding this video but will removing this ring give my kids any more bottom end take off. Mine is a little sluggish on hills and take off
What torque do I tighten the 17mm nut to and any suggestions to do so?
18
Right on. Thanks very much!
what is the top speed now? I have a 2009 model and it only goes about 13mph but I'm planning on doing this, I'm 13 and I got to make sure I do it right so thanks for the video! there isn't that many more out there I don't think
will do double the speed brother! be safe and enjoy!
+DrHighchair that's awesome! thanks again looks pretty easy to be honest
+BigClosetJunk easier than wiping you own butt...lol
Lol yes
perfect video. do you know if the kfx50 has this too?
the 50 does not. At least I don't think so. I have one here that is a 07 and it doesn't have one in it
DrHighchair right on thanks this one is a 2014 kinda hoping it does lol
can i do this on a 2020 Yamaha Raptor 90 ?
I have the same one but it's a kfx 50 will it work for my quad to?
Yes
Does anyone happen to know the proper name of this "speed collar"? (or part number?) Kawasaki lists no CVT collar or speed collar.
charles bacinelli .. spacer. Part number 92026
Thank you VERY much!!
i have a 90cc artic cat 2012, think its the process for it, removing the collar.That case just pops off correct, mines wont budge
Matt Thomas.. some of the clutch covers (that case you refer to) you have to actually remove the kick start first. make sure all the bolts are out too.
thanks
Could I take the speed coller off for when I want to ride it to go get the mail bc we have a long driveway and stull be able to tighten the throttle stop screw for when my son still rides it and everything will be OK
Yes! Being it has that Phillip's head stop screw on the throttle idk why they even bother putting that collar in!
@@whiteoprahOG thanks for the reply I am going to take the collar off right now bc i have all the rpm just trying to go down the driveway
@@whiteoprahOG so I pulled the outside of the primary clutch off did not let the back one slide out. Put the 17mm back on and when I put the cvt cover back on i found 2 stainless steel cylinder looking spacers half inch to 3/4 of an inch long. Where would those have come from
@@whiteoprahOG I started it and it moved forward a couple feet fine I am just scared to test ride it bc i don't want to mess anything up bc I just bought it yesterday. 2020 kfx90
@@whiteoprahOG I tried finding your website but could not figure out what one it was
Made mine actualy keep up with my 2013 Trx 90 and the Kawasaki is 2008
Can the small speed control ring break over time and cause problems
frankie terry .... it very well could... but i doubt it would.
I have the 2015 Kawasaki 50cc. When the case is off, and the belt is exposed, the 90cc shows a black, half circle cover with a hold at the top. The black cover would be about the size of a golf ball if it were a full circle. The hole is slightly larger than 1/4in. On the 50cc I have a gear coming out of the spot where the 90cc black cover is. The 50cc also has a gear that is on the main bolt we take apart to remove the speed collar. It's about 6in across. Anyone know if these two gears should be connecting? Not connected the quad still moves forward. Maybe this charges the battery? Do I need to get the belt looser and tighten the bolt more, so these two gears connect?
Thank you for the video. Your directions made this a snap. On the 50cc I could not get the bolt off with a hand ratchet or my electric impact. I had/got :0 to purchase a pneumatic impact driver to get it off. How do you know if you have it on tight enuff when using an impact?
loganwebd ...Lotta confusion there...lol...sounds like the gears are for the kick starter.
Yep, they were for the kickstart. Easy back together and done. Thanks for the video
I accidentally pushed mine in on a 2015 model. That little black moon looking thing above front clutch. Does that matter? Don't want to put back together if that was bad. Trying to get speed collar. Thanks for the video. Please let me know if you have a suggestion on hoe to wedge the cover. Don't have impact drill
Hey I'm stuck on 2:25 when taking off the bolt. What type of. drill do i use
Daniel Saucedo ....need some sort of impact. or a breaker bar and go d a way to bind the clutch
Does removing the speed collar damage anything on the bike?
Ripped the gasket, used some high temp gasket maker because im impatient lol
Will this also work for the 50cc kfx I have a 2015
Chelsey estrada ....yes
Will it have any negative effect on the engine?
Aslan Khatsiev....none what so ever. may even be better for the engine.
I tried this and I got inside but the pully kept turning. u dint know hot to make it not turn help please
I have the same prob. How is it staying stationery for the impact driver??
does anyone know if those plastic rivets are re usable or do you need to replace them?
You can reuse them over and over. Just be easy with them removing them
white_oprah I just did it on my sons 2020 KFX 50 and it was exactly the same and runs great. But you definitely need an impact for that one bolt.
That mustve been why that thing was so fast!
