How To Rebuild The WP AER Motorcycle Forks

[@jmeezy4050]

This video was fantastic. I turned a 17 minute video into a 2 hour job but next time will be faster. I've been paying shops to rebuild my forks for 7 years. No More!

[@andrewmapes8205]

fantastic tutorial, I feel confident in doing these forks now.

[@rmatvmc]

Awesome! If you have any questions let us know. Thanks for watching!

[@mudpro200]

Thanks for the vid. I buy all my parts from RM MC because ya'll are willing to take the time to teach us on these vids.

[@rmatvmc]

Glad you liked our "How-To" *Motoholic!* That's what we like to hear :)

[@stevemarquez9628]

I just finished doing the full service on my forks. This video was my go to throughout the process. I think now I could do it in an hour.

[@youtubeaccount9058]

Nice, there are a lot of steps here, it could have dragged out for an hour but it doesn't because of good presentation and good editing.

[@nomdeguerre13]

will be doing mine this week, have the service manual and all, but this video is easy to understand and very much appreciated...yep, my parts come from RMATV :)

[@smokepony]

Thank you so much for creating this video! It gave me the confidence to do my own fork service for the first time. Got all of the specialty tools from you guys in advance, and it was downright easy using the video as a guide. Cheers!

[@rmatvmc]

Really cool to hear *Dean Thomas.* Thanks for watching and shopping with us!

Awesome video! Then the link taking me to all the parts I need to do this was absolutely amazing, well done!

[@rmatvmc]

Thank you!

Can you please makes another Video about the air catridge in the legt fork tupe

[@stevegigliotti73]

Thanks you made ez thats Why I buy my gear from you Guy keep up with the videos .

[@rmatvmc]

Awesome! Thank you!

[@gregweever5895]

Awesome video, not had one apart yet but so easy. Love it

[@sethjeffreys3055]

hope you guys can do one on reshiming the right fork for diffrent terrain

[@2wheels4life27]

Seth Jeffreys ya that would be cool id like to do mine for woods riding ...softer.

[@karlkelley8353]

Nicely done......saved me! Thanks so much. 😊

[@duken4evr]

Wow. That is so easy even I can do it - LOL. Thanks for the video. Just got an '18 KTM 300 XC with these forks.

[@ronvissia6464]

Thankyou so much for this helpful video. Followed step by step and seems to have worked out perfect!

[@maverick2242]

I thought the manual suggest heating up the lower part of the uppers where it tapers out to 50c before doing the pulling motion? If you don't have the fancy orange tube protector, can use a small plastic bag or condom lol.

[@BenWard251]

Great video. Thanks! Would love to see a video about the inner air cartridge as well.

[@mikefrey123]

Same amount of oil for both the left and right forks??

[@KevinSpeese]

I drained the air from the schrader valve and the fork sucked into the compressed position under a strong vacuum. Forks only have 50 hrs on them and was working fine. 2019 Husqvarna FX450. Going to consult a friend who has the same fork. I'm guessing a seal may be bad, or I just need to leave like 10-20 psi in the fork. I wasn't planning on changing any seals during this service. My 1st time working on AER forks. ANyone have similar experience?

[@mullermartini227]

you guys do great videos. I wonder why you guys haven't done a video on rebuilding the inner dampening chamber on the non air side of the WP aer48 forks?

[@peaceprayer595]

Awesome Video!!!

[@jakubwozniak5523]

Hello, i can't bleed the oil cartridge, new air bubbles appear all the time, I have already made an up and down movement about a hundred times. Does this indicate a defective cartridge seal?

[@66AGW]

It is possible to put the stop ring in wrong position? Not in order you mention in the video

[@akrider174]

Air side cartridge does not get oil correct?

[@schoolofmoto3419]

How are you torquing the inner tube on top of the forks? Is there a torque wrench attachment that is large enough to fit?

[@robertdebono2810]

All well but it's better if you drive the gide before the oil seal instead of hammering together they will go in sweeter one after the other apparti this good instruction there is the need of cleaning over used oil and polishing dirt blast on chrome. Rob. malta

[@taks9398]

What’s the reason for letting the air pressure out of the inner chamber if not rebuilding it?

[@gilamesse]

Have you had stiff shocks after the rebuild?

[@rmatvmc]

We would recommend double checking the air pressure to make sure it's not too high and causing them to be too stiff. Most people are running about 145 to 150 psi.

[@hyposez1129]

So basically WP XACT forks with AER technology have damping functions on the right side and air on the left, i understand the left side(air side) but is the damping side like coil fork or is it just damper, spring, oil or is it damper and air or something?

[@wrenchone5003]

Thanks again !

[@ekosetiyono807]

How much oil in catridge n out shock bro ?

[@hreindustries]

I have a 2007 suzuki RM125 and need to replace the fork seals. What video would I want to refer to, to help me with that?

[@razvansava91]

Hello mate, what happened if I put motul sae2.5w in this fork? Is that good for this fork?

[@maverick2242]

Good vid cheers, well presented as always, some good tips and info cheers guys 👍

[@rmatvmc]

Thank you *MaverickDH* sir!

[@maverick2242]

Question is that digital air pump you are using, is the battery in it USB or even rechargeable, I bought one a while back and after a year of use, the battery died, the manufacturer Fox said they're were a disposable unit and not rechargeable or battery replaceable, so that went to the bin, thank you Fox! I have an XPLOR so it's not an issue for me now, probably never touch an air fork again! I'm a set it up right and leave it type of guy! But I think it's worth mentioning if those pumps have moved on and are rechargeable or the battery is atleast replaceable without having to dispose of the whole pump? Cheers guys big fan of Rockymtn 👍

[@rmatvmc]

Our Tusk Digital Suspension Pump offers an auto start and shut-off for long battery life - battery is replaceable (CR2032). Sorry to hear that about your Fox pump.

[@grutzmac]

What weight oil is used for the cartridge damper?

[@rmatvmc]

We used the Bel-Ray High Performance Fork Oil in the 5W for this video.

[@李宗穎-t6y]

Hello. Want to ask you all the questions? I bought a group of zx10r Showa BFF, and I need detailed maintenance BFF there is no more nitrogen on it. How much nitrogen do I need to add? Thank you

[@RagerSVK]

12.8 ounce is 3.6dcl? and 7ounce is 2dcl? :D

[@juanjoserodriguezmacias5329]

how much oil do i need?

[@chill9940]

The problem I’m having is the bottem bolt won’t come loose it just keeps spinning I have tried to push on the fork

[@jasonpeterson4166]

Great video! Thank you

[@stevenmcilwrath5371]

Can you tell me if the compression cap removal tool for 4cs forks fits the aer forks too?

[@rmatvmc]

The 4CS and AER forks use a different fork cap compression tool.

don't quote me on this but i think the number is just the fork dia. like same fork just smaller.

How to add preassure to 2016 model AER Forks if i don't have that plug which allow to screw inn pump ? Should i buy any special kit with that?

[@rmatvmc]

The shock pump should have come with the correct adapter to allow you to screw into your AER forks air valve. What model bike and air pump do you have?

[@dawidworwa1206]

@@rmatvmc I'v got KTM 250SX 2016 with standard aer forks WP for that model , hasn't buy any pump yet cause i don't have that plug on top of forks, only 2 screws. Have no idea how to fix it

[@rmatvmc]

@@dawidworwa1206 That bike should have come with 48mm WP 4CS forks, KTM went to the AER forks in 2017 on the SX models here in the U.S.. Did you put the AER forks on your bike?

[@dawidworwa1206]

@@rmatvmc so that means 4CS is not possible to check preassure or pump it up? ? Can't find anything about that

[@rmatvmc]

@@dawidworwa1206 The 4CS forks are not air forks so you wouldn't be able to check air pressure. But we have a video showing how to rebuild the 4CS forks if you want to check that out and make sure those are what is on your bike. If your goal is to get your forks to be stiffer, you can still accomplish that by using your compression clicker. The compression adjustor should be the clicker located on your left fork. You can check out the 4CS rebuild video here: kzbin.info/www/bejne/rqvRZ35upt6qh68

[@tonychambers4302]

Nice vid very helpful

What would happen if I forgot to open the compression completely? -.-

right on!!

[@maxharte3694]

Here's how you do it everybody, you take the air cartridge out of the fork and you throw it away. Then you do yourself a favor and buy a spring conversion kit, you can thank me later. -A very disgruntled aer fork user

[@spencerjohnson5474]

Anyone else rewind like 20 times to try and hear the change in pitch when the fork seal fully seats? Still couldn't hear what he was talking about lol

why is the air cartridge grease not shown? , it seems that they do not remove the oil change and the keys are taken apart, in a word the video sucks!
