Been using rocky mountain videos for around 8 years now... Still the best videos around for maintenance by far ! Will be attacking mine tomorrow with this on the laptop in my workshop. Thanks guys !!!
This is easily the most informative video I've seen regarding servicing my bike. Excellent job on this, informative and easy to follow. I'll be saving myself tons in the long run by servicing my forks myself. Thanks!
@Mike Mo Thats awesome! Thanks for the feedback! That is our goal with these How-To Videos so it's good to hear it helped. We know moto is expensive but hopefully these can help save everyone a few bucks.
sorry to be so offtopic but does anybody know of a tool to log back into an Instagram account?? I was dumb lost my password. I would appreciate any assistance you can offer me.
@Bo Jacob Thanks for your reply. I got to the site through google and I'm in the hacking process atm. I see it takes a while so I will get back to you later with my results.
BTW, I used the green/orange dual compound SKF seals on my last rebuild. Oil was brown and lots of dirt caught up under dust seals. Not good! I'll be going back to the green ones from now on.
You guys did such a great job on this! I repaid the favour by ordering my parts from Rocky Mountain ATV, took some notes watching the movie and all went well. Thanks so much!
My dealer no longer likes me cause I learned a lot from your videos and am one of your most loyal customer for buying all my motorcycle needs on a monthly basis.
Tip for anyone doing this and having issues getting the fork seal deep enough to seat the retaining clip. Before driving the fork seal in, use your seal driver to seat the large washer that's on top of the fork seal first and then drive the fork seal in. Spent about 30min fighting mine until I did this.
Thanks to your video guys!! I just serviced a friend 350 sxf bladder forks with seals replacement... great how-to... thanks guys... we saved and learn... I knew how to work KYB cartidge forks but I was new to these WP... nice units...
Once again a great video guys! One point that I would like to draw attention to is that it is imperative to avoid using a impact wrench when removing the rebound adjuster on the bottom of the fork leg as the hammering action of the tool can disturb the delta shims in their relative relationship to the corresponding ports on the mid /rebound piston.
how nice it would be to live in a country large enough that overnight couriers any parts you need, and not have to wait months while your fork leg is disassembled. Gotta love NZ
Excellent video guys. Just one comment, on the final bleed at minute mark 15:26 it would be helpful to know that if the damper rod "does not fully extend by itself" you most likely have a bad oil-seal which is located inside the Screw Sleeve ( # 76). The oil seal is called "PISTON ROD SEALING", it is # 75 on the parts list, P/N: 48600471. I am currently rebuilding forks on my 2007 150SX & one fork will not fully extend. This happened before & replacing # 75 fixes the problem.
Thank you for the knowledge, guys! I have the same problem on my 350 sxf 2012 (the damper rod does not fully extend by itself). Do you have an idea which part should be replaced in my case? Or is it possible that the air pressure is too low to extend the rod?
***Another part that will keep the damper rod from fully extending is"PIN KIT" #54 on the parts list (P/N: 48600977S) This was the case on my 2012 350 XC-F.
awesome video. Thank you so much. I'd give you ten thumbs up if I could. The costs for doing this the first time myself were about the same as when I had gotten it done by someone else, because I had to buy the special tools needed for this. Nevertheless, it was a fun project and I did learn a lot. A word about to be cautious with the pin valve of the inner cartridge would have saved me 30 minutes of desperately trying to get that thing back in.
Hello great video, my 2009 ktm sx forks have locked up while in storage. Could you give some information on why this would have happened and if it's an easy fix thanks
I got your seal/bushings kit. The little rubber thing you stick the needle through leaks all the 17psi pressure out. I replaced it and it still leaks. I'm using a 23gauge needle. Thoughts?
WOO! I just bought a 2014 ktmsx and was worried I wouldn't be able to do the fork work. I'm lucky I found such a good video for my bikes forks! This may be the best bike tech video I have seen on youtube, great job RMATV! I actually just bought a ton of fork stuff from you guys for my bike. I bought some fork 5.0 fork springs to put in my forks when I do the work since Im 230lb. Should I remove any of the white preload spacers when I put the stiffer spring in?
Hey great video rmatv but I have few questions.. What size seal driver is needed for these forks? It's commonly known as 50mm fork for the very top but fits 48mm tripple clamp...is that right? And how much fork oil should one get to do both forks?
HI.i need a little advise.. i don't have the air injecting tool but a friend does. Is it possible to finish the complete job and do this later when i meet him for a ride with the fork installed on the bike.
Hello. I need your help. I have one of this close chamber to put on my xcw250 2017. Xplor sucks. 😉 I Wil put some pair of new springs,. 40 to get soft feeling. I will put new seals and new oil 5w. The problem is that I remove everything but unfortunately I push the low into cartridge and oil outs from bleeding valve. Is any problem with that or is best push some fresh oil? Best regards sorry for my English
do you ever need to put air in the bladder. If i am bottoming out, would there be any reason i would need more air in the bladder. I am also confused on the air part, do you unscrew the bladder access wholes once in a while to let air out like the other bikes? Sorry i just had my suspensions done by professional last year and found the front was bottoming out.
Amazing video and very informative, someone correct me if I'm wrong but based on what I just watched it is not necessary to rebuild the inner cartridge assembly as long as you are only changing your fork and dust seals?
Great video, thank you very much. One question, I'm on the lighter side (135 lbs) and have had my forks valved for my weight, is the bladder psi going to be the same regardless?
Is it necessary to use the suspension pump and the needle because I don’t have these types of of special tools or is there any other way to get around it for a ktm sx 250 2 stroke 2010
365 milliliters or 635 milliliters for each fork leg? I'm so confused because I found in some forms they said you need 2liters of fork oil for do the both fork legs but you saying 365 for each required...
hey guys great video as usual , i was just wondering my forks are leaking past the bottom clicker is it just as simple as follow the first few steps and replacing those orings? cheers
Thanks for the reply. I was just telling a friend I might use a broom handle and shop towels. :) How about using non- chlorine brake parts cleaner? Have everything torn down and changing all seals and bushings with the Pivot Works kit.
Jeff Loucks Yea as long as you are replacing both oil and dust seals, brake cleaner is fine. Note, wipe down the tubes dry before installing the new seals. Hope this helps
I have the same fork on my sx144 and it makes clunking noise when fully extended - going over whoops you can hear the noise and feel space in the suspension. I have not seen any oil leaks . What could be the problem?
Is it possible to take oil seals off without loosing oil ??? I mean for example screw off down side of fork like at the beggining of the video and Then just push fork out without screwing off, upper side of fork ??? Critical sitution :( . I have wp suspension from 2008
Well you are supposed to be changing out your fork fluid periodically. Your service manual will tell you the intervals on when to change the fork fluid and seals. We recommend changing out the fork fluid and oil seals together. Hope that helps. Thanks
Hello guys, thank you for this very useful video. It helped me immensely to service my forks. - I have the nitrogen needle and will get the pump as well the only thing I need is the adapter between the pump and the needle => where can I get that from please? Is that something TUSK is selling as well? Thank you for your help in advance. Regards Ales

i always see the awesome race bikes from ktm, honda, and yamaha on your videos. how about some of the thumper bikes from time to time? I ride a drz400e and i'm sure you know of the following of riders the drz holds. show some love rmatvmc!
The Duke there’s no volume you over fill it so that it’s completely full of oil...once you install the bladder and fill it, it will purge any extra oil out and be full...
You said the manual calls for 365 mil of oil , question is this.. Is this 365 mil of oil in addition to the oil put in the top blader getting the air out?
Hey rocky mountain atv mc would you know why my fork has no rebound control and just shoots back up alot faster than its partner It's not an upside down fork its from a 1999 tm 250 en any ideas would really help the fork with crazy rebound has a leaky oil seal that i am about to fix but i am not sure that this will help with rebound rate PLEASE HELP
I can recommend you fix that leaky seal and rebuild the fork with all new fluid. Then dial in your clickers.. rebound/compression. That should give you a good starting point.
THANK YOU FOR QUICK REPLY when i adjust both rebound and compression in the leaky fork leg i can't get any rebound dampening at all but when i do this on the other leg i can feel the difference would the leaky fork oil seal cause loss in the ability to control rebound
Tm'250 gasgas125 Do you know how long the fork leg has been leaking for? Depending on the amount of oil loss yes, it could be the reason why you're not able to control the rebound
Tm'250 gasgas125 Awesome 👊 ! For sure do both fork legs. Also, pay attention to the good fork leg when disassembling.. you may find something reversed from the fork leg that's leaking and why it's not rebounding as good?
Is it necessary to do the whole rebuild?Can I just replace the seals and bushings,fill it with the correct amount of oil and put it together.Skipping the whole bladder deal?
+Binkke I guess.. if you're looking to save a few bucks and some of your time. Our Tusk Digital Suspension Pump comes with the Race Tech Nitrogen Needle in a kit for $77.99. Keep in mind that the fork oil in the inner chamber that you are bypassing is going to get dirty and eventually prevent the flow rate. We did our research on these forks and these steps that we demonstrate are the best way to rebuild them. Here's the link for the Suspension Pump: www.rockymountainatvmc.com/p/3545/50671/Tusk-Digital-Suspension-Pump
i was thinking the same thing thanks for the response. Next year i'll do the whole thing but this year just wanted to do the basics. Are you able to put a link down for this kit? the race tech nitro and and needle kit?
@@tgaydos99 Yes the tops were perforated so I sent them to Stillwell Engineering it's an easy fix. It looks like KTM is bringing the bladder forks back!

Thanks so much, you saved my ass !
This has been my go to video whenever I rebuild my forks. Great guide without the BS. Thanks heaps boys.
BTW, I used the green/orange dual compound SKF seals on my last rebuild. Oil was brown and lots of dirt caught up under dust seals. Not good! I'll be going back to the green ones from now on.
You can’t beat a company that provides the best prices with step by step installation videos.
You guys did such a great job on this! I repaid the favour by ordering my parts from Rocky Mountain ATV, took some notes watching the movie and all went well. Thanks so much!
This video is why i will be buying parts from Rocky Mountain and trying the work myself instead of taking it to a shop. You have a new customer.
Why would anyone dislike this video ? Nice work RM ATV !
My dealer no longer likes me cause I learned a lot from your videos and am one of your most loyal customer for buying all my motorcycle needs on a monthly basis.
Tip for anyone doing this and having issues getting the fork seal deep enough to seat the retaining clip. Before driving the fork seal in, use your seal driver to seat the large washer that's on top of the fork seal first and then drive the fork seal in. Spent about 30min fighting mine until I did this.

Absolutely outstanding ho-to video. Perfectly clear and informative. Thank you for this guys. It is very much appreciated.
Brilliant vid, allowed me to rebuild with ease 😎👍🏽
Thanks you very much for this video ! It's look so easiest when we got special tools !
But, how can we do nitrogen with air pump and nitrogen needle ?
Hello great video, my 2009 ktm sx forks have locked up while in storage. Could you give some information on why this would have happened and if it's an easy fix thanks
Where do you find that lillte nut adapter thing to go on the motion pro needle and that goes into the tusk air compressor
Would it be bad to replace seals and bushings but not touch the cartridge?
I got your seal/bushings kit. The little rubber thing you stick the needle through leaks all the 17psi pressure out. I replaced it and it still leaks. I'm using a 23gauge needle. Thoughts?

Nice video but you guys did not show where all of the parts of the rebuild kit go, including where a few damper parts go on the inside of the fork...
This is the same as ktm 2013450sfx factory edition?
amazing video you guys, I order alot of parts from you now. Cant thank you all enough for these!!! Pin it to win it!

Perfect Video
I have the same fork on my sx144 and it makes clunking noise when fully extended - going over whoops you can hear the noise and feel space in the suspension. I have not seen any oil leaks . What could be the problem?
Thats the springs in the forks have lost length and have lost thier preloaded length hence the noise and loss of stroke resistance id say
Are the both forks the same construction?
The steps shown in this video will be the same for both fork legs.
hey great video, is this the same fork as the KTM sxf 350 cairoli edition 2011?
Yes, should be. You can always verify with your service manual or make sure your fork caps look the same as the ones in the video.
do a kyb psf -2 plz!
Is it possible to take oil seals off without loosing oil ??? I mean for example screw off down side of fork like at the beggining of the video and Then just push fork out without screwing off, upper side of fork ??? Critical sitution :( . I have wp suspension from 2008
