Replacing your fork oil and seals is part of regular maintenance and helps ensure your suspension operates properly and internal components don't wear prematurely. In this video, Charles shows the proper steps to rebuilding a Showa Twin Chamber Fork that came off a 2005 Honda CRF450R, but this procedure will be the same for many Honda dirt bikes with 47mm Showa Twin Chamber forks.

I just performed service on my Showa forks and followed the instructions of this video. It was a piece of cake to do and my bike now handles so much better with the oil in both chambers changed out and the seals replaced. Charles and RMATVMC, thank you so much for your help. Buy all my stuff through you guys because you guys are all around the best.

Thanks for watching and giving us feedback!
Used this video to rebuild the showas on my o6 kx250 two stroke a very good step by step video thanks RM
Perfect paced, clear information. Good job.
I like the details in this video. Gonna do my seals tomorrow
one day we will see Betas getting some love in this channel!
That was really helpful! Charles you do an outstanding job.
Thanks so much for this video! Huge help whilst doing my forks, first one took me about an hour, next fork about 15mins!
yea great video! wish every how to vid was like this one. well done!
Thanks, glad it helped! -Charles
You guy are the best, my go to people. It's awesome what you guys do, and thank you for it..
I teach motorcycle repair at a technical high school. My students better not spray any aerosol cleaners into the same pan where we drained the oil into, because it contaminates the oil to the point where it cannot be hauled off for recycling. Just a note for folks that must recycle oils. Bill Ross - Region 10 Technical High School - Brunswick, Maine
Hey teachers! Leave the kids alone!
Haven't heard that one before. Oil recyclers just ask that you don't dump a ton of antifreeze into the waste oil. Matt - auto mechanic 9 years, Wisconsin.
I just burn it.
Thanks so much for creating and sharing all these awesome videos with us!!!!!!!!!! :) Very Much Appreciated!!! Love having the links to the tools in the description too!!!
Awesome video. Thanks!!!
Nice video. Helped me alot with my 2017 kx 250f
12:23 Amazing instructional video. I have a problem, however. Whenever I get to the point at the end when I am resetting the rebound clicker, the clicker itself does not move. Does the rebound clicker get automatically tightened (thus not allowing it to move when you are ready to adjust your clicker) when you torque the rebound adjusting nut?
Parabéns pelo vídeo, ajudou bastante!! 👏👏👏
De nada! Ficamos felizes sabendo que o video te adjudou
Nice video. Those showa's are pretty simple
I lil bit quick lots of going back but figured it out
If I am just trying to replace to fork seals do I have to take the damper apart?
You need to remove the inner cartridge to get your inner and outer tubes apart, but no, you don't have to disassemble the damper.
Good job 👏
The Tusk push rod holder was to big to hold the rod holder from interfering with the lock nut. A strap works if you run into this to hold the push rod out so you can loosen or tighten it.
What are the respective amounts of fluid, the inner cylinder (top cover) and the outer cylinder? Thank you.
i think 145-160ml
you just need the oil for it to play the piston rod.
then the bigger tube needs on your liking or the stock oil level
Great in depth detail.
I want to know like how can we know which model forks are installed as i bought the bike from someone,and that person had installed these honda crf forks aftermarket. I am not able to ascertain the model year,and because of that i have not been able to order part for these forks
Great content 💪
Ottima manualita' complimenti!
Great video thanks
Great video guys Can you specify which types of seal grease do you guys prefer , as I am indian and racetech grease is far-off my grasp. Please specify NLGI 1,2,3 WHICH IS SUITABLE ,and is silicone grease or lithium or regular grease will work without causing leaks
Great video
hola. muy bueno el video. yo no puedo purgar el cilindro interno.
Thank you for the video! Tell me which brand of oil would you recommend for use?
We used Bel-Ray High Performance Fork Oil 5W for the forks in this video. Glad it helped and thanks for checking out the video!
@@rmatvmc could you recommend it to me as an alternative to the more expensive Honda oil ? Sorry to bother you , there's no one else to ask)))
I’m not understanding why oil has to go into the damper... I’m sure I’m wrong but it seems like that would make to much oil in the forks when you put the recommended amount of oil back into the fork. Or do you subtract a certain amount of oil from the end amount of what you put in the damper?
Rm can you pls tell people to check the owners manual because I'm working on the same front forks and my forks take 50ml more oil so I have to take my forks back apart and fill em more
likewise i pumped it a several times but it doesnt work, the rod still not extend, what is the alternative way to remove air from the inner chamber?
Could I re-use my new fork and dust seals that I replaced a few months ago if I need to change bushings now?
When should i replace the dust seal? Mine is pretty worn but dont know if its worth replacing?
thanks man
Thanks I have your graphics
Hey there. I just bought a 2014 CRF 450R and the forks have an mcr A kit inners. I am wondering if this is the same as th Showa fork inners and if replacing the seals are similar or the same procedures. Never had these types of forks before and need help maintaining these. Thank you.
HELP!! My center bolt on the dampener assembly (bottom of fork) is STUCK. I cannot get it loose to remove the dampener assembly. Can anyone help with getting it unstuck??
showa produced 47mm and 49mm, where did they based the diameter from? (inner or outer tube?)... are most parts interchangeable?
Blew my right seal on my 450L while riding in the black hills. Not looking forward to this ngl lol
Same on my crf250rx. Not looking fun. Might be worth respringing it when I’m in there for my fat ass
I’m guessing you got it replaced?
@@nalyd6386 yup both ended up being blown and I just had honda powersports do it for me. $250 for just a reseal for both forks but it needed done
@@aidanvelthuis1267 haha ya im glad I don't have to deal with that problem anymore. I used to be underweight for big bikes but now I'm ideal weight for the stick specs
@@-PlayMaker- I’m doing it to my 2008 Crf250r forks, seems alright, I just watch a lot of you tube videos. If you ever have to do it, you don’t need all of these specialty tools, I did my forks on my 2004 crf150f but these forks won’t compare to those ones.
I am trying to get the cap assembly back into the damper but I simply cannot get the threads to engage. I’ve done everything by the book but it’s as though it is not inserting completely. Any suggestions? What am I doing wrong?
Hi, yeah it can be tricky. Double check the oil level and make sure it's not to high. Then, push the damping rod up as far as you can without spilling any oil out. Then insert the cap assembly, push down and thread in. This can help minimize any air that you would have to compress. Other than that, sometimes people install stiffer springs in that cap that can make it harder to push in. -Charles
*too
Hey just checking to see if you know... But is this video relevant for a 2021 set of showa forks?
Yes it is!
@@rmatvmc thank you!
Hi guys.
When i put the damper unit all the way down on the piston i hear air in the upper unit and oil is coming out of the two holes and the piston rod do not moving the last 1,5 " . And when i put in the damper valve unit earlier into the piston i hear air coming throug the seals i think. Can you help me ?
Is this the same process for the kyb aos forks?
If my front right fork is perfectly fine but my front left fork has been leaking. Should I change both or just my front left one? Just asking 🙌
I would say it depends on how long it's been since you changed your seals and oil, if you've got around 20-30 hours on your forks, then it's a good idea to do a full service anyway. But if you have less than that, then yeah, I would only worry about the one fork seal. - Chase
I have the 2020 Tiger 900 Rally Pro which has a Showa fork, but I can’t figure out which video would work for this fork or any literature on how to rebuild it at home. Any recommendations?
Triumph service manual.
Hy. oil capacity bottom and top? motul fel oil expert light 5w?
Are that’s the forks for a 2002 yz125. Thx
You'll want to watch this one and reference your manual for specs. ua-cam.com/video/Y43k1qFVGW4/v-deo.html
How would you torque down the fork cap on the top?
Some specialty wrenches have a cut out for a torque wrench. Just snug it, all this torqueing of shit is a bit excessive.
ugh, not looking forward to this with my KX250F
Same🙁
Hey man, I was thinking of buying either a KX250F or a CRF250R but looks like i'll pick KX250F cuz of Honda's terrible forks.. you think it's a good idea?
@@ppsh2294 yeah, I think you'll be happy with it.
@@gophop aight, ty
mine is leaking from the bottom
I followed every step but why when i put them on my bike, and compress them they dont go back up easily i gotta pick the bike up for them to go back to fully expanded
You most likely have air in your inner chambers. Did you do the test and make sure the compression rod fully extends on its own before putting them back together?
@@rmatvmc hey guys, I’m having a similar issue. I put the 195ml into the dampener chamber, pumped the air out, put the assembly back in, tightened it down and the rebound test doesn’t work. Not sure what I’m doing wrong.
@@mctudor2010 I was having the same issue. I did it several times with the same results. Ultimately I just added a little more oil than the spec calls for and then was able to get full extension. I figured the extra oil just gets purged anyway.
How much oil in that suspension???
382ml in these forks. You can see this step at 12:05 in this video.
@@rmatvmc how much oil in inner Chamber????
@@rmatvmc 382 in the external Chamber??
195ml of oil goes into the damper (7:18 in this video).
@@rmatvmc thank you Very much for your attention🤙🤙🤙🤙🤙🤙🤙🤙👍👍👍🤝🤝🤝🤝🤝
I just finished rebuilding my dual chamber showa forks and have pretty much no compression in them I'm not sure what is going on I would greatly appreciate any info
No oil in the closed cardridge system
Have you pumped it and filled the 193ml in?
If that doesn't help just text me on Instagram @Mustermusli24
Would this effect the custom tune I have on it if I rebuild it?
Not unless you change the valving or amount of oil in the forks.
Hoza ?
0:25 Ha you said doo-doo
He said dodo
Great video dude but no need for safety glasses 🥽
Great video, only seen better during Factory KYB training if you want basic training. However my 1 issue is that you give these videos away for 'no charge', every tom, lad and harry can come and view them. The problems this causes in the industry is not good, people attempt to try to do things without really knowing what they are doing, without the correct tooling and often not for a good result. I have just spent a day rectifying somebodies 'Home DIY' work with many new parts on a Showa twin chamber fork, it has cost the customer hundreds of pounds in spare parts because the last person to attempt them was a butcher! In all seriousness though, you could and should charge good money for these videos. Mark @ SSR Suspension.
Charging for UA-cam videos, I bet you'd be ecstatic to pay each time you breathe
