Hiya from the UK! Thanks for these videos you guys have made, they make life so much easier when you see how stuff is put together! You've saved me so many times from making mistakes 😂
Hi Rocky MTN. I got my parts this afternoon for my 2016 YZ 250. I had a badly leaking rear seal so a service was necessary. I had the shock off and sitting on my work bench until the specialty tools and parts arrived. I took my time, followed this video step by step in my garage and about 1 to 1.5 hrs later I was done. I will get the nitrogen in the next couple days then I can slap it back into my bike. I really appreciate your time making this video to help me learn my bike better and save some serious cash. Great job!!!
Thank you for the video! I'm rebuilding my yz426f rear shock and forks with stronger springs so I can do bigger jumps and not bottom out, and they needed new soft parts anyway. This was my first shock rebuild so I have a few words of advice for others to avoid my mistakes, which can be seen in a soon to be posted video: 1. I'd recommend going ahead and removing the valve stem first thing, it makes the step of pushing the seal down easier so you don't have to worry about building pressure. 2. The Bladder is attached to the bladder cap; I used air to press the cap out and it popped out and didn't realize there were supposed to be attached. 3. Don't neglect to remove the peening from the top of the bolt. I tried to simply use an impact and destroyed the threads. I repaired them with a m12-175 die but I couldn't get 30 ft-lbs on those threads so I got as much as I could and welded the nut on cause I can't get a replacement fast enough for my trip! 4. A battery powered inflator or 12v car inflator works well for putting pressure on the bladder. 5. Don't get the bump stop and Seal cover placed wrong way around! I accidentally did. I wasn't about to remove the piston again (and couldn't have disassembled it anyway cause of welding the nut on) so used a hot knife to cut the bump stop off and re-attach it back in the correct place. It isn't pretty but should work and I'll still be able to ride in 2 days!
Not only is this a great video on how to work on a shock, it is an excellent primer on how to make a how-to video. Excellent camera angles, great timing on the voice-over.l This is a pleasure to watch!
Excellent video! Thank you for convincing me to sell this dirt bike lol I literally put the forks back on this morning, now the rear shock has a leak. Like a puddle. I think it got jealous of the fronts getting rebuilt. What a process! Its a 2006 RM85 that I'm working on. Im counting on the rear shock to be a little more, Chinese, than the one you've rebuilt here, and thus, maybe simpler to dissect.
This method of filling and bleeding is sooo much easier then using the compression adjuster port as shown in another video. This was fast and easy!! Thanks!!
justin's video is also good and constructive for many folks who would never consider opening up a shock to wach and understand that this is not for them however they still get to look over the shoulder of a pro like justin and watch along. good video justin nicely edited also.
That was one of the best videos I have ever saw. Everything was clear, well thought out and all camera angles were correct to show exactly what was being talked about as each part was described. I think a person who has never held a wrench in their hand could have a good chance with that video. Very well done.
great instructional video. Amazing how the internet has made things that used to intimidating very doable. Thanks RM. Ive been ordering a lot of tools and parts lately from you and they get here quick. BRAAAP on
hi from the UK. just used this video to help replace the seal on a kyb shock off my klx 250. really easy to follow with no rushing through. rebuilt and back on the trails. thankyou Rocky Mountain. Nick.
Hi wow that was a while ago lol i can't remember what size but it was a pretty standard seal available from a company called "All balls!" Sorry can't help further bud.
Here in 2021, Excellent video, Gives me a new faith in Mankind in General, People can be Generous with their knowledge and share with the rest of the public...then others can be the opposite of Generous. Rocky Mountain ATV are the best of the best. 5 STARS in parts and service.
Didn't see you inspect the shim pack for bent shims, also nice new nut on the shaft for the re assembly. The bleeding is another area where most guys will fail. The addition of the nitrogen is actually the easiest part.
hello, Thank you for awesome video. However, I have few questions for you. 1. how do you remove 2013 Kawasaki KX450f rear shock reservoir cap, since it uses a needle to fill in gas, and nothing to grab on to pull to bring it out? 2. When you inserting the seal housing in to the oil, doesn't """some air"" gets trapped under it? 3. Should you drill a small hole on the side of the seal housing below the large outside O-Ring to get that air out, to remove as much as air possible? 4. if small amt of air gets trapped inside the shock from seal housing installation , will that cuz a problem? (Or any air in general) 5. do you have a recommended Suspension Setting(front and rear)and Oil Height on the front forks for 2013 KX45F, AND oil "viscosity" used on front and rear fork and shock? thank you very much for all you help and time making this video.
10:39 Does the tightening torque of the nut affect damping characteristic, is it an adjustment of the shim preload or doesn't matter if I torque a little bit more or less?
hello thank you very much for the good work. I live in Brazil and have nothing on the gsx750f 2006. shock absorber. You would have any video on this motorcycle. mine leaked the gas and a little oil in the coupling of the hose.
Of course. Clips are out...I ended up using compressed air from the reservoir side and it still took some doing. I've done a few shock rebuilds and they rarely come apart easily.
Wow I just read a few of the other comments. Seems like Im not alone in my thoughts. really nothing more to say. I do believe it has all been said. Props to you guys.. !!
You forgot to flip the shock upright and bleed any remaining air trapped in the shock out the bleed screw or compression adjuster (removed) ,I attach a small funnel with threaded end screwed into the bleed hole and half fill with oil making sure the hole is at the highest point usually slightly tilt the shock body to achieve this then slowly compress and pull the shock shaft in and out watching for air bubbles raising into the funnel of oil once clear remove funnel and screw bleed cap back in , recharge with 1bar nitrogen and install the spring
i have a question, i want to do it for my kxf 250f unitrak shock, i dont understand in the time when you fill with oil and put the piston assembly, when do you close it? i mean when you purge, with compresed piston or descompresed? i cant explain it, look at 13:10 minute, in that part its my question, doesnt vary the level of fluid? because if its descompressed it will be more space for fluid, if it compressed less space for fluid, ? please help me, im getting crazy hahah!!! thanks! really good your video
Monica Armentano You would just want to follow this video honestly. You would want to purge the system with the piston up and out or "decompressed" to get all the air bubbles out. Then pour more fluid in and install your piston. Thanks for watching our video man!
Lol, everything always works perfectly in the videos, but meanwhile here in the real world.. Shove the seal head down with the tool, but as soon as I stop pressing down, it pops right back up again. Same for the bladder cap. Valve core is out of the bladder so that's not the problem. Take it to a friend's shop tomorrow and lock it down in a vise so maybe I can press down with one hand and pry the lock ring out with the other..
Same experience here as you on disassembly. Now I'm about to reassemble, thanks to this video, and not looking forward to getting the circlips back in. DId you find any trick 2 years ago when you did this? :-)
The video is a tremendous help. Thanks! One question, how do you swap out the copper looking bushing that rides on the outside of the piece that sits between the groups of valve shims. I got the pivot works kit so I have a replacement bushing but it's not split like the fork bushings. 2016 YZ250. Thanks!!
I have a question related to the website. i had free shipping on orders over $50 on my account and now it is gone. i just wanted to know why but great video lots of help.
jrod koz Thank you for commenting. Your free shipping on orders over 50 bucks was most probably a limited time offer code that may now be expired. You can call in and talk to one of our CSR's for more information @ 1-800-336-5437
Hi there. I have a ohlins shock . The shaft has the rebound needle inside of it . The shock has a plastic nut to adjust it manually but the needle get stuck in the up position and when I turn the nut to make the needle go down , the nut stop clicking because it get stuck in the up position. Do you know if this is normal ? Or what can I do ? The problem start whit oil leaking. Now I'm thinking it was leaking from the adjust nut because retainers and seals look good for me . Thanks
Thanks for the video, it is very informative, but I have a couple questions. Won't the punch marks between the nut and shaft cause damage to the nut the next time you try to remove it? Will the high strength thread locker require heating before nut can be removed, and if so, could the heat damage any of the shock components?
@Poop On-i-JUNKs 1. I haven't had a chance to tear into one of the newer shocks yet but there should be someway to connect or attach a tool to pull the bladder out. Have you removed the retaining ring? 2. There is really no way to get absolutely 100% of the air out. The goal is to remove as much as possible and tapping and running it through the stoke as shown in the video will help with this. 3. No, definitely do not drill anything 4. Explained with question 2 5. This is affected by too many different variables to have one setting for your bike. I would start with stock settings and the recommended oil and adjust to your conditions from there. Thanks for watching!
Bloody informative. Just wished that you had this video up a few years back when I had problems getting a someone decent to rebuild my Ohlins. Even back then without full knowledge, I knew that the guy was doing a screwed up job.
Question: The main shaft assembly of my CR250 shock (Showa) doesn't come out as easily as in the video. I've tried wiggling it out and tried pushing compressed air thru the reservoir with the compression backed all the way...and still it won't come out. Any suggestions...?
Shawn Warner I would make sure that you've gotten all of the inner retaining clips out.. but as long as you have followed this video, it covers pretty much all the steps for both Kayaba and Showa shocks.
Hi, I have pulsar 220 in my bike while turn right or left side the center stand hits the road and making a voice can you suggest me how to resolve it.i think 220 has very low ground clearance and maintaining the air pressure in front tyre 30 and back tyre 40. please let me know ur suggestions Thanks in Advance!
Hi Guys! Great video, it helps me a lot! I am currently rebuildig a Yamaha YZ 250C from 1975. Do you have any idea which oil i should use? Or who I cpuld ask. Any help is aprechiated! Thanks a lot!
Most suspension shops will recommend you have your suspension serviced anywhere from 20 to 50 hours but it will really vary with how aggressive of a rider you are and the conditions you're riding in. But many riders who are just weekend warriors will change fluids at about 40 hours and rebuild once a year. But you can check out your bike specific service manual to get a better idea of what your particular shock recommends. Hope that helps!
What's the best way to fill a kyb shock for a 2011 yz450 where the reservoir is 90 degrees from the shock body and not parallel like in the video? Do you use a vented plug for the body while filling the reservoir?
You can fill it through the valve adjustment hole. Maybe you can do it this way. Make sure you let the air pressure out of the bladder! th-cam.com/video/tu85Fnx8UPU/w-d-xo.htmlm53s
When I was disassembling mine, while unthreading the piston nut, the shock shaft unthreaded from the yoke/clevis/bottom piece instead. Rebound clicker was backed out all the way so I just impacted it back in there. Hopefully it's fine.
2 year update for anybody wondering (or possibly myself revisiting, like I am now for another bike lol) -- the shock shaft coming unthreaded from the yoke caused no issues, and that bike's still a-ok today.
this might be a stupid question but if its a nitrogen filled bladder, is it ok to use normall air? and if i want to pump mine up can would it be ok to have a air/nitrogen mix?
Dry Earth air is approximately 78% nitrogen already. The only reason pure nitrogen is recommended to fill a shock bladder is because nitrogen molecules are larger than oxygen molecules, and it will take them longer to migrate through the rubber bladder. Oxygen molecules could (theoretically) migrate through the bladder, create tiny bubbles in the oil and lower the pressure in the bladder. If you're a pro racer, that may be a concern for you; but for most of us mere mortals, there is no disadvantage to using dry air if you can get the pressure high enough
Igor Vinicius Nitrogen gas is used to keep the shock running cooler. Nitrogen can transfer heat out of the shock oil much more effectively than normal air can. Its up to you, but i would refer you to your service manual for the bike. Thanks for watching our video!
Igor Vinicius Keep in mind that normal air is 80% nitrogen, so using compressed air is generally not a problem unless your system is running to extremely close tolerances. A lot of tire places are really pushing to sell nitrogen these days because they can't make money from you filling up your own tires.
Andy Greenwood the other reason for using pure Nitrogen over regular compressed air is that compressed air will leak through the bladder rubber over time. Nitrogen does not leak through rubber and also maintains a much more accurate pressure under temperature variations. I used to use compressed air in my ATC's back in the day because back in the 90's it wasn't common place to get Nitrogen unless you want back to the Dealership and in most cases they horrendously over-charged (probably because they were angry they didn't get to rebuild the shock and charge that labor) :)
i have a 2005 kx250f and the manual says 142psi nitrogen but im using light weight maxima racing shock fluid. so, if i put about 150psi nitrogen in, would it substitute and make the shock stiffer?
Ya know, I don't know? I would first recommend going with a heavier shock oil wt. before playing with the bladder pressure. Especially when the manual say's to use 142psi. For Safety reasons, i would go off of what the manual says and pressurize the bladder to 142psi and use a heavier wt. shock oil.
Rocky Mountain ATV MC i'll just fill it to what the manual suggests, better safe then sorry but thank you for getting it more clear on what i have to do. best source by far!!!
Great video! I really want to do the front and rear valving by my self. I have a 12' YFZ 450R. Do you have any experiense on those KYB shocks in particular? Thanks!
Excellent presentation. The only thing I would question is why the shock bumper wasn't replaced while everything was taken apart. Those bumpers will age and split over time, which is what mine did. They're not that expensive to change and that one in the video looked rather old. Otherwise it's an excellent tutorial. I used it step by step to change out my bumper.
Rocky Mountain ATV MC good video. I have just bought a pretty run down XLR250 1991 model. I am planning it to be a full rebuild project. While at it I would like to upgrade my bike too. Do you have parts that I can use on my bike? And do you ship overseas to Malta?
Checked the OEM parts guide (1997 YZ125) and I cannot find the replacement nut for the shock shaft. I ordered an All Balls seal replacement kit from RM and one was not included. Do you know where I can get a replacement nut? Also, is the nut used from OEM of specific metal/ compound? Last question; on the next rebuild would you have to grind the new replacement nut down again to remove? Thanks in advance- love the videos.
David Andrade If you needed to replace that nut you would need to get the OEM one from the OEM schematics. To answer your last question, we use the loctite with the added punches just to simply add to the locking of that nut. It would not require any grinding to remove if needed rebuit again. Thanks for watching!
Kevin Vienneau Oh no! Your service manual won't list this information so my next bet would be to get with Race Tech and see if they can help you with the order of these parts. Let us know if there's anything else we can help you with.
I can't remove the shock shaft and seal head. I can pump it, but it won't separate from the body. The seal head circlip is out and everything is clean. Ideas?
Nice video. I'm considering a bladder conversion for my 2013 WP shock (linkage). I would think this procedure would work fine when eliminating the piston reservoir would you think?
The main reasons for not using regular air is that the nitrogen is free from moisture and it also wont heat up (thus expand and create more pressure), but it wouldnt be the end of the world if you didnt use nitrogen. In my service manual for an 01 RM250 I had, it said moisture free air can be substituted for nitrogen
Hiya from the UK! Thanks for these videos you guys have made, they make life so much easier when you see how stuff is put together! You've saved me so many times from making mistakes 😂

Thank you for the video! I'm rebuilding my yz426f rear shock and forks with stronger springs so I can do bigger jumps and not bottom out, and they needed new soft parts anyway. This was my first shock rebuild so I have a few words of advice for others to avoid my mistakes, which can be seen in a soon to be posted video:
1. I'd recommend going ahead and removing the valve stem first thing, it makes the step of pushing the seal down easier so you don't have to worry about building pressure.
2. The Bladder is attached to the bladder cap; I used air to press the cap out and it popped out and didn't realize there were supposed to be attached.
3. Don't neglect to remove the peening from the top of the bolt. I tried to simply use an impact and destroyed the threads. I repaired them with a m12-175 die but I couldn't get 30 ft-lbs on those threads so I got as much as I could and welded the nut on cause I can't get a replacement fast enough for my trip!
4. A battery powered inflator or 12v car inflator works well for putting pressure on the bladder.
5. Don't get the bump stop and Seal cover placed wrong way around! I accidentally did. I wasn't about to remove the piston again (and couldn't have disassembled it anyway cause of welding the nut on) so used a hot knife to cut the bump stop off and re-attach it back in the correct place. It isn't pretty but should work and I'll still be able to ride in 2 days!

necessary to bleed shock when just replacing spring?
How often do shocks (front and rear) need to be serviced for the average woods/trail rider? Thanks.
Question: The main shaft assembly of my CR250 shock (Showa) doesn't come out as easily as in the video. I've tried wiggling it out and tried pushing compressed air thru the reservoir with the compression backed all the way...and still it won't come out. Any suggestions...?
Shawn Warner I would make sure that you've gotten all of the inner retaining clips out.. but as long as you have followed this video, it covers pretty much all the steps for both Kayaba and Showa shocks.
very good vid I have had dirt bikes for years never stop learning I live in QLD Australia they don't do vid like this here might learn to much thanks.
Ha ha that is awesome! Glad we could help. Thanks for watching.
Where do you find these rebuild kits?. And can you please state distributors. Tjx
The first link in the video description will take you to a page with shock rebuild kits and tools.
I want to see this done on a reservoir that's 20 years old. This is nice and clean so it's going to be easy
Hi, I have pulsar 220 in my bike while turn right or left side the center stand hits the road and making a voice can you suggest me how to resolve it.i think 220 has very low ground clearance and maintaining the air pressure in front tyre 30 and back tyre 40. please let me know ur suggestions Thanks in Advance!
Hi Guys!
Great video, it helps me a lot!
I am currently rebuildig a Yamaha YZ 250C from 1975. Do you have any idea which oil i should use? Or who I cpuld ask. Any help is aprechiated!
Thanks a lot!
Wow, I think id rather pay someone to do this. And I'm usually all for saving money by doing it myself lol
Ya I'm trying to be that person yikes !
lol the amount of tools needed
10 seconds in "imma head out"
Really it’s super easy lol you don’t need any of those tools
Right and you know it’s done right
Can the 2001 YZ 125 stock monoshock be repaired?
Perss Perss yes
How often should a rear shock be rebuilt and or fluid changed?
Most suspension shops will recommend you have your suspension serviced anywhere from 20 to 50 hours but it will really vary with how aggressive of a rider you are and the conditions you're riding in. But many riders who are just weekend warriors will change fluids at about 40 hours and rebuild once a year. But you can check out your bike specific service manual to get a better idea of what your particular shock recommends.
Hope that helps!
Do you know what is the rear shock oil seal size of CB1300? I guess it is 11.6 * 24 * 5.
What's the best way to fill a kyb shock for a 2011 yz450 where the reservoir is 90 degrees from the shock body and not parallel like in the video? Do you use a vented plug for the body while filling the reservoir?
You can fill it through the valve adjustment hole. Maybe you can do it this way. Make sure you let the
air pressure out of the bladder! th-cam.com/video/tu85Fnx8UPU/w-d-xo.htmlm53s
When I was disassembling mine, while unthreading the piston nut, the shock shaft unthreaded from the yoke/clevis/bottom piece instead. Rebound clicker was backed out all the way so I just impacted it back in there. Hopefully it's fine.
2 year update for anybody wondering (or possibly myself revisiting, like I am now for another bike lol) -- the shock shaft coming unthreaded from the yoke caused no issues, and that bike's still a-ok today.
this might be a stupid question but if its a nitrogen filled bladder, is it ok to use normall air? and if i want to pump mine up can would it be ok to have a air/nitrogen mix?
Dry Earth air is approximately 78% nitrogen already. The only reason pure nitrogen is recommended to fill a shock bladder is because nitrogen molecules are larger than oxygen molecules, and it will take them longer to migrate through the rubber bladder. Oxygen molecules could (theoretically) migrate through the bladder, create tiny bubbles in the oil and lower the pressure in the bladder. If you're a pro racer, that may be a concern for you; but for most of us mere mortals, there is no disadvantage to using dry air if you can get the pressure high enough
Hello friend, needs to actually use gás? I can not use compressed air?
Igor Vinicius Nitrogen gas is used to keep the shock running cooler. Nitrogen can transfer heat out of the shock oil much more effectively than normal air can. Its up to you, but i would refer you to your service manual for the bike. Thanks for watching our video!
thanks
Igor Vinicius Keep in mind that normal air is 80% nitrogen, so using compressed air is generally not a problem unless your system is running to extremely close tolerances. A lot of tire places are really pushing to sell nitrogen these days because they can't make money from you filling up your own tires.
Andy Greenwood Thanks for your comment man!
Andy Greenwood the other reason for using pure Nitrogen over regular compressed air is that compressed air will leak through the bladder rubber over time. Nitrogen does not leak through rubber and also maintains a much more accurate pressure under temperature variations. I used to use compressed air in my ATC's back in the day because back in the 90's it wasn't common place to get Nitrogen unless you want back to the Dealership and in most cases they horrendously over-charged (probably because they were angry they didn't get to rebuild the shock and charge that labor) :)
What bullet cap would I need for rebuilding showa shocks on crf450r/crf450x? Specifically model years 2010+?
Thanks Rocky Mountain ATV MC!
Really do not need the annoying music, distracts from the video.
Can i use compressed air insted of nitrogen? Thanks?
How much shock oil does it generally require?
i have a 2005 kx250f and the manual says 142psi nitrogen but im using light weight maxima racing shock fluid. so, if i put about 150psi nitrogen in, would it substitute and make the shock stiffer?
Ya know, I don't know? I would first recommend going with a heavier shock oil wt. before playing with the bladder pressure. Especially when the manual say's to use 142psi. For Safety reasons, i would go off of what the manual says and pressurize the bladder to 142psi and use a heavier wt. shock oil.
Rocky Mountain ATV MC i'll just fill it to what the manual suggests, better safe then sorry but thank you for getting it more clear on what i have to do. best source by far!!!
You're welcome anytime. Thanks for asking and good luck!
Hi
do you have tutorial on how to rebuild monoshock of XR125?
XR125 2014
Sorry, unfortunately we do not have a video on the shock of that bike.
Sir. Can i use normel air with out nitrogen
How long can bleeding take? I have blisters and still see bubbles
:(
I'm having the same issue! They are never ending I don't get it
Brian Wilson then air is still coming in from somewhere else.
Brian Wilson it’s a very tedious task...
Great video! I really want to do the front and rear valving by my self. I have a 12' YFZ 450R. Do you have any experiense on those KYB shocks in particular? Thanks!
Excellent presentation. The only thing I would question is why the shock bumper wasn't replaced while everything was taken apart. Those bumpers will age and split over time, which is what mine did. They're not that expensive to change and that one in the video looked rather old. Otherwise it's an excellent tutorial. I used it step by step to change out my bumper.
should a sachs shock be the same a this one?
Rocky Mountain ATV MC good video. I have just bought a pretty run down XLR250 1991 model. I am planning it to be a full rebuild project. While at it I would like to upgrade my bike too. Do you have parts that I can use on my bike? And do you ship overseas to Malta?
Doesn't look like we ship to Malta.
Checked the OEM parts guide (1997 YZ125) and I cannot find the replacement nut for the shock shaft. I ordered an All Balls seal replacement kit from RM and one was not included. Do you know where I can get a replacement nut? Also, is the nut used from OEM of specific metal/ compound? Last question; on the next rebuild would you have to grind the new replacement nut down again to remove? Thanks in advance- love the videos.
David Andrade If you needed to replace that nut you would need to get the OEM one from the OEM schematics. To answer your last question, we use the loctite with the added punches just to simply add to the locking of that nut. It would not require any grinding to remove if needed rebuit again. Thanks for watching!
Very informative video even if this is too advanced for me right now. it's still cool to watch!
+Shaine MacDonald Thanks, glad you enjoyed it!
Kevin Vienneau Oh no! Your service manual won't list this information so my next bet would be to get with Race Tech and see if they can help you with the order of these parts. Let us know if there's anything else we can help you with.
Anybody know where to get the seal kit for an 87 KDX200? And any tips would be much appreciated
This is why Evo idaho is a gangster and makes the big bucks!!!!
Is there a video for KYB?
Sorry, unfortunately we do not have a KYB shock rebuild video.
Excellent Vid. appreciate it alot.
commenting to keep it alive!
I can't remove the shock shaft and seal head. I can pump it, but it won't separate from the body. The seal head circlip is out and everything is clean. Ideas?
Nice video. I'm considering a bladder conversion for my 2013 WP shock (linkage). I would think this procedure would work fine when eliminating the piston reservoir would you think?
Is this the same procedure with a 1989 lt500 rear shock?
Does this fix a bouncy shock?
Is it worth going to a professional suspension tuner like race tech or can an avid mechanic re-valve their own forks and shock with the same results ?
Hi, nice informative video. I have a question my shock had no oil in it when removing.
Nice question
I bought a shock bushing for this job. But didnt realize I should have bought some sort of driver also to get the old out and new in 🥶
I know this might be a dumb question but do you have to refill it with nitrogen air??
Yes.
@@rmatvmc why
The main reasons for not using regular air is that the nitrogen is free from moisture and it also wont heat up (thus expand and create more pressure), but it wouldnt be the end of the world if you didnt use nitrogen. In my service manual for an 01 RM250 I had, it said moisture free air can be substituted for nitrogen
after loosening the nuts and stuff, when you put it back together, do you have to put anything back into the shock? like fluid or somethin
Oil obviously
juaneer i didn't know if performance shocks had something other than oil.. have respect
No, you just spit in it.
My rear shock on yz125 rear shock is squeaky does that mean it’s bad?
