Thanks MatthewMCRepair! I just blew a fork seal on my DRZ 400 with a RM 250 USD fork swap. This video was exactly what I needed. I know my fork legs were 46mm KYB and I am fairly certain they are 2001-04 on the RM250. These forks work great for me, and they dont look to bad to rebuild.
great video! very informative and well done. unlike many other youtube mechanics, you know what you're doing and speak with confidence. my fork seals on my yz are fine, however the oil is likely due for a change, so i'm glad to use this as a reference
OK I have watched 4 different videos now on this.. Matt you absolutely did a great job on this video and instruction bud.. Definitely using your method.
Excellent video. Thanks for taking the time to make this. I had a doubt how to measure the oil level and you've just cleared that doubt. Cheers from Brazil!
Great video. The whole series I plan to buy as I have 95 kx 250 which is basically the same thing. Small difference if that. I reference your videos a lot
just got new powervalve components and piston in my 02 cost me 700 $,broke it in with some ipone S2 32:1,ran 3 heat cycles letting it cool down between each cycle shes good to go.wasnt able to get the stripped screw out of my carb,i just got a used one off an 01,works just as good.running a 55 pilot and 165 main with fmf fatty/shorty and boyesen rad valve duel stage pro racing reeds,she runs a lil gooey but ive never taken her out on a rip yet im thinkin of doing my forks now they seem spungy
Thank you for making this video. I am in the middle of replacing my seals and was having trouble getting the oil seal to seat, but from watching this it seems I missed a step, as I didn't drive the bush in before the seal.
Hi. Great vid on kx250 forks. Just brought mine 2001 250 same as your vid. Last owner put new seals on. But there is a little bit of play. No leaks tho. One shop wants £130 to check them out. Might try it my self thanks to you. So many different people say it's due to different things. Shims seals and bushes.
If the bushings are worn, the seals will wear quick and cause play like you mentioned. I found the entire rebuild kit for about $40. I say go for the DIY!
Hello my forks off my 99 KX250 did not have the washers under the spring like yours did. I looked at the parts diagram for a 99 and an 01 am they seem identical except for the addition of those springs on the 01. Should I purchase and add to my forks?
Only thing I don’t understand is why I have to touch or unscrew the rebound click on the button and the compression clicks on top like I saw others videos? Is only thing I need to do it. I know my clips from counterclockwise. Thanks in advance.
Your vids very thorough. My seals are good but when the bike sits for a while, the motion of kick stand up and the bikes weight is upright. The forks compress, or sags, or the front drops a bit. Is this a lack of oil?
nice vid, explained very well. i have a 07 yz125. the forks do not leak.they do not stick, however they have like a inch in sag. after i take the bike off the stand the bikes front forks immediately drop a inch. could this be low oil? collapsed spring? they seem to work fine. they just have a inch of sag"free play up and down" thank you kindly.
love your videos Matt got a question I have seen other videos on seals the only difference is that they count the clicks for soft and hard my question is that do you have to mess with those settings or can I just do my seals and not have to mess with those
I have a 2003 kx 250 and the cap on my right fork will not come off. I have the fork on the bike. I just want to change the cap because the softining and hardening screw is stuck. Any ideas? It seems like something is forcing it down.
In addition to the electrical tape, I find a spray of isopropyl rubbing alcohol on any rubber part will let it slide over metal like water off a ducks back. takes a hair longer to dry but is very easy on seals.
Just a heads up, not all rubber materials are compatible with isopropyl alcohol. Granted the amount of time they're in contact with it won't do any damage more than likely but anything is possible according to murphys law. Learned that from dealing with hydraulic systems where the rubbers are definitely in contact for greater periods of time. Been out of practice for a while so I don't quite recall the rubber specs and compatible fluids off the top of my head. Very very mild soapy water was usually my go to. Not sure it'd be the best for a sealed fork though.
@@100GTAGUY You're quite right, but for most motorcycle bits I've come across, we're okay. And it evaporates so quickly I don't worry about rubber eating residue hanging about.
Greatt video I have the same forks on my yz 125 although when I tipped the fork to get the oil out I had no washer come out from under the spring on both sides is this normal? Thanks !
Tom Dnb Hi Tom, not sure on the washer for you model. Double check with service manual or online parts diagram whether washer should be in there or not.
Would a 91 yz 250 be about the same? I watched a different video and the bottom of the fork they took it off with a Allen wrench I think they said 1/2 inch do you have to ? But I saw that you just poped it off without doing that? Thanks
Hi, I have a 99 kx250, and that washer you put in after the fluid level check is not on a 99, I checked the parts finche on 00 01 and they have it but not on the 99, first I thought who ever worked on the bike didn’t put them back in, weird, what’s you take on that, thanks
Appreciate the video. The oil seals took several minutes to remove with a knife/screwdriver, the bike only has 3700 miles on it and I'm guessing they have never been changed. dirtridermag says that if you don't use a torch before popping it out you can damage the bushings, is that true? Having a hell of a time removing that clip, do you have any tips for getting it out? The forks are off a stock 2004 KTM 625 SMC.
I haven't had any forks that gave me a lot of trouble, so I can't offer any advice there. I know it is common practice to use heat when bushings are difficult. Maybe use penetrating oil on clip?
Hi. Congratulation for video. Was following the steps but I had a problem here. To leak oil fell a small piece and a spring inside that tube. Now do not know how to ride. Can you help me?
I followed all the steps and put it back together. But when I push the fork down it looked as hard as yours. But the clickers dont seem to do anything. By turning them and pushing the fork down
I have a kx250 2005, I've kept it in the house since I bought in 05. I don't ride it much. The other day I loaded it up in the truck and when we arrived I noticed oil around the front forks on the floor of the bed. (I am a novice when it comes to mechanics) what could be the problems? Thanks
kawasaki makes a special tool to service that specific part of their kayaba forks. part number 57001- 1287. fork requires to be dissasembled before tool can be used for its purpose. im not sure if tool can be used on other types of forks
Excellent video man. I know the video was made a while ago so not really expecting a reply. I got an 01 cr250 that doesn't have the stock forks but I've managed to work out that it has 46mm KYB's on it from a similar era as the ones you're working on in your video. How do I figure out what seals and bushes to order for it?
MatthewMCRepair on the axle clamps it has 5kz3 marked on it which is a honda number I think so I can only guess a cr of some sort. I have asked on some forums and people are saying they are 46mm kyb open chambers
Dude i love your vids. I subscribed to you. You seem like the only person i could get to do this favor for me. I have a 2011 ninja zx10r. I have Showa Big Piston Forks and i cannot find a video to save my life on how to change the seals on those. Do you think you can post a vid please?? PLEASE!

+Jaime WR250 You are welcome!
Thanks man, this is helpful. I've done forks before but they were classic style forks, not inverted. This is super helpful and detailed. Great video.
Great video. The whole series I plan to buy as I have 95 kx 250 which is basically the same thing. Small difference if that. I reference your videos a lot
Hey again.......Yet another great informative Video. My 15 year old son was able to service his forks from this video.....Thanks very much.....
That's awesome!
Vise grips or pound a smaller socket on? Apply heat to outer tube, it might make it easier to bust loose.
Followed instructions made the seal driver, worked like a charm, great video much appreciated.

you make the best motorcycle repair videos on TH-cam!!!!!!!
I gave up working on it and started riding it!
I have a few more vids on the kx250 that I need to edit and upload.

MatthewMCRepair Entire rebuild kit is $40 per shock or for both ? I think I just got hosed....
+JP Graba I bought this kit which is for both forks:
amzn.to/1KhsLAw
Matt
MatthewMCRepair So this kit is different from what I see advertised as fork rebuild kit
+JP Graba Rebuild kit = service kit. Same thing. It has everything you need to do both forks. Also buy some oil.
Matt, is the lock nut on the damper rod supposed to snug up to the fork cap or snug down to the spring guide?
No problem! Check out the fork removal vid.

Top show mate.What an awesome fork video, many thanks from Aus man.
Like the way you take your time and do it to the book, very good work and keep the videos coming, massive tumbs up! Fair play
Thanks!
Thanks for the great videos.Just replaced the fork seals in my 05 KX125.Could'nt have done it with out your help.Thanks for sharing your knowledge.
+tndeere No problem!
Matt on the oil level height did you say 70-75mm. Most specs say about 100 mm from the top of the fork tube. I just wanted to double check. Thank you.
Justin Pelton Justin, follow what your service manual states. If you have a KX125/250, then head to my site and you can grab the manual for free.
thank you so much this will help me with my 98 kx250 . all the videos i saw were with the newer models of the kyb fork
Only thing I don’t understand is why I have to touch or unscrew the rebound click on the button and the compression clicks on top like I saw others videos? Is only thing I need to do it. I know my clips from counterclockwise. Thanks in advance.
When I pull the rod up to "bleed" the fork oil comes out of the center? Is that bad?
How much oil was poured into the shock absorber ??. Thank you if you answer. Thank you
great video. gave me confidence to do my forks. my wr250x i only want to change the oil on them. how far in disassembly do i need to go to change oil?
After the oil is dumped out, fast forward video to fill part.
Your vids very thorough. My seals are good but when the bike sits for a while, the motion of kick stand up and the bikes weight is upright. The forks compress, or sags, or the front drops a bit. Is this a lack of oil?
I don't know sorry.
😥 thanks for the reply
I got some little metal rods that fell out where do they go?
WOW !!!! Movies great .... I learn lot of good with you for my Kx 250 THANKS
Thanks Daniel! Go enjoy that KX250!
I'm about to change my fork seals and thanks for explaining all the parts helped out a lot bout to go change fork seals
No problem, Russell. Good luck changing them out.
Will it work for yz 1994 250 4jx model
Thanks! I'll be posting more on the KX250, sit tight.

+obray317 I'm not sure. If I recall correctly, the manual states to back them to the softest setting before disassembly.
Thanks Matt I figured it out keep up the good videos
+obray317 OK great.
I have a 2003 kx 250 and the cap on my right fork will not come off. I have the fork on the bike. I just want to change the cap because the softining and hardening screw is stuck. Any ideas? It seems like something is forcing it down.
Make sure top triple clamp bolts are loose and bottom triple clamp bolts are tight. The top ones squeeze the cap sometimes.
Thanks for the response. I had to take the fork off to get it off
Michael Cain So it sounds like the tight triple clamp was preventing you from loosening the cap.
In addition to the electrical tape, I find a spray of isopropyl rubbing alcohol on any rubber part will let it slide over metal like water off a ducks back. takes a hair longer to dry but is very easy on seals.

Ok i have an 02 kx 250 and on the top of the fork the top cap thing is stripped because it was so tight and any tips on how to get it off?
Should it be the same on 1993 kx500?
What should I do about stuck adjuster screws, the bleeder screws are locked too.
Start by soaking them and walking away.
@@HTMR I did, WD and PB Blaster. I'll keep at it.
@@motoozark4361 Have you removed the fork cap? If so, try some heat.
Greatt video I have the same forks on my yz 125 although when I tipped the fork to get the oil out I had no washer come out from under the spring on both sides is this normal?
Thanks !
Tom Dnb Hi Tom, not sure on the washer for you model. Double check with service manual or online parts diagram whether washer should be in there or not.
thank you,,noticed your not making any more kx 250 vidz did you give up on it|?
Hey will you be posting any vids for a kx125 bikes?
No sorry.
How much oil did you put in it?
saved me another €140 now i can do it myself thanks alot mate!
Thanks!
Thanks buddy!
Would a 91 yz 250 be about the same? I watched a different video and the bottom of the fork they took it off with a Allen wrench I think they said 1/2 inch do you have to ? But I saw that you just poped it off without doing that? Thanks
Not sure about your model sorry.
Hey, I am about to do my forks in the next couple days, I only ordered 1 liter of fork oil, will that be enough oil or do I need to get 2 liters?
Hi, I have a 99 kx250, and that washer you put in after the fluid level check is not on a 99, I checked the parts finche on 00 01 and they have it but not on the 99, first I thought who ever worked on the bike didn’t put them back in, weird, what’s you take on that, thanks
I have no idea, sorry. Follow the service manual.
Great, well instructed video. Certainly helped give me some confidence in replacing the seals on my Yamaha WR250.
Thanks for the compliments!
Awsome! Awsome Vid!. Thank You for this vid. It helped rebuild my kids '02 cr125's forks. Thanx again👍
Where can I buy a tool from you for stuffing parts? That white plastic?
And I'm interested in a strip of gray as it is called and where it might be purchased
Outstanding! Great work, and great instructions! Thank you so much!
Do you know if the kayabas on the 2009 yz250f are the same as these?
Great vid by the way, makes the job look very doable.
Nope, those are different.
Appreciate the video.

MatthewMCRepair Thanks, a smaller scredriver got it easy
Hi !! i got a problem my rebound and compression damper screw are stuck .... does not move at all !!! Any Suggestion ?? Thanks
Is there corrosion on there or something? Try soaking them in penetrating oil. Make sure dirt is not causing the problem either.
Hi. Congratulation for video. Was following the steps but I had a problem here. To leak oil fell a small piece and a spring inside that tube. Now do not know how to ride. Can you help me?
***** What piece and spring?
I followed all the steps and put it back together. But when I push the fork down it looked as hard as yours. But the clickers dont seem to do anything. By turning them and pushing the fork down
Круто! В верхней части вилки, там где пружина интересно какая последовательность сборки идет
Your forks are frozen? Seems like you need to take things apart.
nice fork seal driver, could I find something similar at home depot? and what are the demensions again?
I believe it was a 1 1/2' SCH 40 Tee. I cut in half lengthwise. Yes HD will have it.
MatthewMCRepair what do you think about the electric tape method for setting the fork seals, does it work ?
Good video man! You should do a video of the psf kayaba fork. Ive been looking for a video to help me with my kx450f fork rebuild.
+faweebus Thanks! I this this video is what you are looking for: th-cam.com/video/G0dLM_IoIOQ/w-d-xo.html
tanks for the video! do you have the service manual for a kxf 450 2011? tanks from argentina!
Sorry, don't have that manual. Check out tradebit for cheap manuals.
I bought the same maxima oil you got but it says 10 instead of 5 like yours... Will this work for a 2006 Yz250f forks?
it will work fine it's just a heavier weight oil so the fork will be a little more stiff
Thanks man
I would like to know what's the oil level for a Yamaha yz 85 or how many onzes? please I need it.
+RAUL RIOS I don't have the manual for that bike, sorry, can't give you the oil level.
Nice work man !! Very good quality video's

Yes, however I believe your forks are different than mine. Check Rocky Mountain ATV channel, they have videos that you need.
Thanks!
HI how manny inches supposed to be the fork oil from top to bottom?
Bernie Plantar What year make model are you working on?
+Kelseylov3 mine is a 2001 kx250
+Kelseylov3 Visit my site for the service manual and pour in what it specs out. I can't remember off the top of my head.
I have the same forks but one is leaking at the very bottom where the compression adjuster is how do I replace the o ring
Not sure, haven't had to do that repair yet.
kawasaki makes a special tool to service that specific part of their kayaba forks. part number 57001- 1287. fork requires to be dissasembled before tool can be used for its purpose. im not sure if tool can be used on other types of forks
How is the oil level?!
I have a 2006 kx250. is that the same as this you think?
I think you have different forks. RM ATV may have a vid on your style:
Fork seals, change on motorcycle part 1 (of 2), twin chamber
Excellent video man. I know the video was made a while ago so not really expecting a reply. I got an 01 cr250 that doesn't have the stock forks but I've managed to work out that it has 46mm KYB's on it from a similar era as the ones you're working on in your video. How do I figure out what seals and bushes to order for it?
Do you know what bike the forks came from?
MatthewMCRepair on the axle clamps it has 5kz3 marked on it which is a honda number I think so I can only guess a cr of some sort. I have asked on some forums and people are saying they are 46mm kyb open chambers
I would ask a suspension shop, they would know for sure. Maybe you can buy parts from them.
I have a 2000 Rm250. Would these forks be the same as the ones your working on?
+Guzman3605 I believe so. The kit is not the same PN though.
Thanks, but this won't apply to your CRF, the forks are different. RockyMTN has a good vid for those forks.
what is the inner tube diameter please?
amazing video. going to tackle my forks next weekend.
My forks won't move and I can here the springs inside do I have to do this video
Fork oil tool = $15
Seal driver = $40
Torque wrench = $40
Saving yourself time and doing the job right = Priceless
Is the 2004 model Kyb?
2001
Dude i love your vids. I subscribed to you. You seem like the only person i could get to do this favor for me. I have a 2011 ninja zx10r. I have Showa Big Piston Forks and i cannot find a video to save my life on how to change the seals on those. Do you think you can post a vid please?? PLEASE!
Dulema, I don't have any vids on that model at the moment.
any body know if these are the same forks on a 2008 yz250f?
No.
What seals do u recomend, oem or all balls?
I like to use OEM.
I have the exact same forks, but mine does not have that internal washer. It's not in the microfiche either. Strange.
Well, I can't answer that one!

I think 1 1/2"
how much oil goes into one fork
I forgot, grab the service manual from my site: www.howtomotorcyclerepair.com/category/service-manuals/kawasaki/
Glad it helped.
Are these forks air forks on your kx250. My 14 kx450 has the air forks but they seem different to take apart compared to the spring forks
No they are not air forks.
Thanks for the videos!!!! I have a 99 kx250 that I have to change de seals..
I know what tool you're talking about. The Motion Pro seal bullet. I don't even think it's like $6 for one. Nifty little thing.
Yes, maybe I'll pick one up one day.
This video helped me a lot...Thnx:)
Great vid , thanks 👍
But why not opened inside down tube?
Not sure what you mean. Can you elaborate?
MatthewMCRepair I want to say that you have not completely removed from the tube ..inner tube down there and gather a lot of misery ...
GodfatherMaxi Oh ok, I did not completely disassemble since I did not need to. I just needed new seals and fluid.
Killer movie buddy thanks for the info
thanks man i just do me forks service now me bike feels like new in the track
