Dude, I have learned so much from all your Tech Lessons Videos! So incredibly helpful for those of us who have not done some of these maintenance processes before. Going to do my CRF front suspension this weekend. And you have inspired me to want to powder coat my hubs when I re-lace my wheels with new rims. Nice job on this channel. Thanks for making such excellent, instructional videos!
I just stumbled across this older video and I must say you're much more enthusiastic in your later videos. Lol. Good info nevertheless. Thanks Cameron. I hope you're feeling ok.
You add air after filling the shock with oil and pumping the shaft several times. The compression adjuster must be out when adding air to the bladder. When you add compressed air to the bladder it should push out the cap a little and make the air bubbles go to the top where the compression adjuster hole is.
No, you will need to release the nitrogen. If you remove the compression adjuster with the bladder pressurized, oil will spray out. And you would not be able to add the correct amount of oil when refilling the shock if the bladder has pressure. Yea, it doesn't take long to re-charge the shock. It's like airing up a tire basically. What do you mean by weight? Weight of the oil or weight of the rider?
Alright, because I tries to pump the shaft to get the air bubbles out when I barley put the new oil in, and I pushed to hard and it came out of the blatter, so I just refilled it and put the compression adjuster screw back on.
Yes, the stock springs are for most 140-160 pound riders on a 250F. 170 should be fine, just make sure you set the sag. I've had good luck with Maxima oils.
If it rebounds too quick it is either mis-adjusted or the nitrogen needs to be recharged or bladder replaced. You should use the recommended oil. 7 WT might be acceptable, but I would not use 10 WT.
Thank you for this video. I tried to change the oil in the shock like you stated but have ended up with some air in there that I can hear. When filling the shock with oil is it necessary to pump air into the nitrogen tank, or can I do that after I have finished the oil change sealing it back up?
Can you just change the oil without releasing the nitrogen? And also I unscrewed the bottom connecting rod and I think it was oil that came out but I'm not sure. And do they fill the schlock with nitrogen in like 20 mins or does it take a while? And can you tell me what weight is recommended for the stock springs for the front and rear are?
I saw that the monoshock disarm completely, even the nitrogen cylinder, so that? I just want my monoshock respond well. It has nitrogen and no oil leak, but the rebound is fast, does not contain the rebound. you think that is? My manual recommends 5w oil, you may put 10w?
XR 250 R for 2000 is the same procedure? can not touch the nitrogen cylinder and only change the oil? I have not as nitrogen reload. How much psi nitrogen is used?
I thought this technique would be easier than taking the whole shock apart but if you have a newer bike it is a pain. my 13 crf450 has a lot of stiction since the bushings are fairly new so when I tried to bleed the bubbles out it would stick and the blow oil out of the hole. wasted a lot of oil and ended up having to take out the clips and pull the rod out anyways because there was still a bunch of air trapped in the shock.
The bladder needs to be empty when filling the shock. Then once it's filled, you add some air to keep the bladder from collapsing before it is filled with nitrogen.
The service manual recommends that it be done every 25 hours, but of course it depends on the rider and tracks. A pro class rider should service their suspension about every 25 hours or less, and a beginner about 35-45 hours.
Most likely there is an air bubble, you'll need to bleed the shock again. If you are not an experienced mechanic, you should bring the shock to someone who is. Having a malfunctioning shock is a serious safety issue.
The process should be similar, but you will need to release the nitrogen and recharge it after changing the oil. Look in your service manual for the recommended PSI.
Great Tech Videos, thankyou. I need to replace the bump stop on a 2006 CRF250R, can I just remove the clevis end or do I need to pull the whole shock down and install bump stop from the top of the shock rod?
+Michael Joblin Thanks! Yes, the easiest way to replace the bump stop would be to remove the clevis. The nitrogen in the bladder has to be released before hand though. Of course make sure the spring preload nut is loosened all the way first too.
+Michael Joblin Yes, I believe so. The manual recommends releasing the pressure. I haven't taken apart a shock in a while so not quite remembering the process.
do unscrew the bolt from the nitrogen container and just pump the fluid out then add more suspention oil also need to know how I would put the air in the container
I don't know about that, it's best to use pure nitrogen as it is more stable under pressure and varying temperatures. I wouldn't risk using the air in our atmosphere.
The bottle if it contains nitrogen. Do not think you can be bad oil? I want to know before decommissioning. If the bladder was bad, would not have nitrogen? my bottle if you have nitrogen.

I really appreciate the kind comments! Glad the videos help!

@Rodrigo Salmerón I appreciate the positive comment! Thank you for watching!
U are the best! Thank you for sharing your technical skills.
So you mean the shock rebounds too slow? Like it is sticky?
You add air after filling the shock with oil and pumping the shaft several times. The compression adjuster must be out when adding air to the bladder.

Great vids, very helpful. Constantly working on the bikes and these are a huge help.
Thanks! I'm glad the videos are useful.
One tip, measure the length of the spring before loosening it so you can put it back where it was and you don't have to reset the sag.
Thanks! Yes, it is worth it. They should be re-greased quite often. I have a video on how to do this on my channel.
There is probably an air bubble or a problem with the bladder. If not, some of the valving shims may be damaged.
Alright, because I tries to pump the shaft to get the air bubbles out when I barley put the new oil in, and I pushed to hard and it came out of the blatter, so I just refilled it and put the compression adjuster screw back on.

Thanks! Hope it helped!
Ok thanks! When do you release the air? Right before they fill it with nitrogen?
Yes, the air needs to be released before recharged. Just fill the shock completely with oil before installing the compression adjuster.
Do you fill the hole where the comp adjuestment is so the excess oil runs out and no air left in shock?
If it rebounds too quick it is either mis-adjusted or the nitrogen needs to be recharged or bladder replaced. You should use the recommended oil. 7 WT might be acceptable, but I would not use 10 WT.
It depends on the application. Some shocks work better with 5wt or 7wt. I don't know your bike so I can't tell you what to use.
Thanks! I don't think a MC19 rear shock is very similar so it wouldn't be the same procedure.
Thank you for this video. I tried to change the oil in the shock like you stated but have ended up with some air in there that I can hear. When filling the shock with oil is it necessary to pump air into the nitrogen tank, or can I do that after I have finished the oil change sealing it back up?

Thank you for sharing your technical skills, more power to you and God bless.
Thanks for watching!
Ok, and one more question, can I just pour the shock oil in without filling it up with air, or do you have to fill it up with air?
XR 250 R for 2000 is the same procedure? can not touch the nitrogen cylinder and only change the oil? I have not as nitrogen reload. How much psi nitrogen is used?
I think I have a big problem with my rear shock, when I sit on it and it compresses, it like has a little spot that it goes to. Can u help me ASAP?
And is there a certain amount of oil you need to put in the shock or do I just fill it all the way up?
Is this about the same on a 2002 CR250?
I want to rebound too slow. The bladder have nitrogen ok :). the oil is the problem do you think? ty from Chile

5WT oil is recommended.
The bladder needs to be empty when filling the shock. Then once it's filled, you add some air to keep the bladder from collapsing before it is filled with nitrogen.
Great video! I was wondering my owners manual says I should use ss-25 but I could only find ss-19?
my friend i have a hagon shock in a yamaha supertenere 750 and i want to change the shock oil.what oil is better to use? 10w or 15w?
can you tell me whats the use of 5 or 10w oil?is it for how fast will work the shock?doew the weight of motorcycle play a role?
gracias amigo por compartir, aprendo cada vez mas con tus videos...Thanks from Chile.
Thank You for watching!
hello, how many ml of oil you put in the rear suspension crf 250?
Thanks!
The service manual recommends that it be done every 25 hours, but of course it depends on the rider and tracks. A pro class rider should service their suspension about every 25 hours or less, and a beginner about 35-45 hours.
And I weigh like 170 pounds, would the stock suspension be good? And what kin of shock oil should I get?
What type of shock and fork oil should I get, like 15w 20w?
Good job Man. Excellent video. Thanks for sharing.
+TheMattholew Thank You, I appreciate it.
Most likely there is an air bubble, you'll need to bleed the shock again. If you are not an experienced mechanic, you should bring the shock to someone who is. Having a malfunctioning shock is a serious safety issue.
Hey man how do I know how much oil and nitrogen to add?
Hey very nice video man, do you think that its worth regressing your linkage bearings while you're down there?
What happens if the blotter collapses before being filled?
The process should be similar, but you will need to release the nitrogen and recharge it after changing the oil. Look in your service manual for the recommended PSI.
I'm not familiar with the shock or type of bike, so I wouldn't know. Most shocks use 5-10 WT oil.
Is it just ait ju filling on or just nitrogen?
Great video!
Whats oil aplication? SAE 10w.
thank you heaps for all these tech lesson's they help me a heap dude :) cheers
Thanks! Glad they are useful.
Great Tech Videos, thankyou. I need to replace the bump stop on a 2006 CRF250R, can I just remove the clevis end or do I need to pull the whole shock down and install bump stop from the top of the shock rod?
+Michael Joblin Thanks! Yes, the easiest way to replace the bump stop would be to remove the clevis. The nitrogen in the bladder has to be released before hand though. Of course make sure the spring preload nut is loosened all the way first too.
+ReVive Moto Parts Oh, ok, to stop oil flowing out through bottom of shaft?
+Michael Joblin Yes, I believe so. The manual recommends releasing the pressure. I haven't taken apart a shock in a while so not quite remembering the process.
Hello, I am of argentina.mi question is:se loads only with compressed air or with nitrogen once finished the replacement of oil?
You will need to charge the bladder with nitrogen.
thanks !!!
It is pretty similar. Changing the oil will be the same general process.
Yes, you fill it to the top so there is no air left in the shock.
do unscrew the bolt from the nitrogen container and just pump the fluid out then add more suspention oil also need to know how I would put the air in the container
what tipe of oil velocity you are using?
I need help.i have a cr85 big wheel and the suspension is far too soft im planning on rebuilding the shock do you think it will do the trick??
Colin Morrison no you will have to get new springs if the suspension is too soft for you
Yes, you can add oil like shown in the video. You'll need to let the nitrogen out of the bladder though.
i dont know what the manual use.its a Hagon shock.how can i find it?
Hey man I have a question I need to remove my rebound clicker how do I do that?? Thanks
-Ben
Can you fill it with oil while it’s on the bike?
My shock is leaking oil, does that mean it's a bad shock and time for a new one?
Great video tutorial. Thanks and ride safe!
I appreciate you watching the video and giving your thoughts!
Thanks for watching! Good luck!
hey is a cr250 1998 shock the same?
Like, is the stock springs meant for people who weigh like 140-160?
Where do you get nitrogen?
My air compressor won't let me put air in my blatter, what should I do
I would use what the manual recommends, but 10 WT would probably be better.
I don't know about that, it's best to use pure nitrogen as it is more stable under pressure and varying temperatures. I wouldn't risk using the air in our atmosphere.
Ok thanks!!!! Your videos are amazing!!!!!!
Your bladder needs to be recharged or replaced. Your rebound adjuster could also be way off.
why did you leak the nitrogen, and what did you put back in it to increase the pressure
whats nitrogen?
Great video!
Great videos Man
i just subbed
can the same methode be done to MC19 Rear Shocks
Thank you for watching!
And how do I find out what is wrong?
Great video! Thanks
Thanks for watching!
There can't be nitrogen in the bladder when you add oil. Air bubbles would form and the shock wouldn't work right.
Damn, any suggestions on what I should do?
wich psi should I use in my yz 85
The bottle if it contains nitrogen. Do not think you can be bad oil? I want to know before decommissioning. If the bladder was bad, would not have nitrogen? my bottle if you have nitrogen.
And by the way, amazing video!!!!!!!
Greate video man! This video helped me alot! Thanks :)
where can i find this part? 4:05
Which part? The compression adjuster or plate?
OneOne9 Creations the adjuster
krakkis
Are you wondering where it is located on the bike, or looking to buy one?
OneOne9 Creations loking to buy one because mine is broke? thanks for replying me back!
krakkis You can purchase them from any online OEM parts dealer such as rockymountainatv.com
Ok what gas you put in it or is it just air lol I have no idea
I let my suspension oil out can I just pour more fluid in the container
awesome video bud.
+dave bram Thank You!
A shop that specializes in suspension would do it for around $150-$200.
It possibly could cause it to leak, but it's just not good for it.
yea rekon you should have taken shaft and piston out cleaned it then refill shock upside down with shaft and piston out
No, the oil will not make it rebound too fast. The bladder would not have any nitrogen if it leaked.
thanks
how do I do that im confused
Ok sweet!! Thanks!!!
Check the service manual.
Nice
Muito bom!!!
