1:11 Rear Shock Service (YAMAHA 2006-2025 YZ450F YZ125 YZ250F YZ250) Changing fluid, Nitrogen charge

Call it a rebuild, its more of just a servicing. Getting it fresh again and good.
Will actually work as instructions for the shock for a lot of pre 2006 YZ's as well.

Nice! Glad to hear it helped! Thanks for watching!

[@alfredjonsson90]

Really good instructions, love that you give reasons WHY you do everything. Keep up the good work mate! Had problems getting the "ring" with a slot in it away from the shock. Had no idea it had a "bumper". Started prying that shit first, but stopped and watched this video, thanks for this!

[@zackk695]

This is actually a great video due to you staying focused on what you’re doing without talking about a lot of nonsense crap like a lot of people do on videos. You also showed me I don’t need to take the entire shock apart to change the oil and nitrogen. Great job. My question is would air be almost the same thing as nitrogen?

[@UpAllNight91]

Thanks. using air will bring in moisture into the reservoir which can rot the rubber bladder over time. I know some have done it to get by and it does work. Some will say the shock can explode from using air but to this day I have not ever heard or seen any evidence of this. Nitrogen is the recommended way though.

[@jamesonkruger6989]

This is the best Rear shot video on here. A little confusing about the holes you drilled

[@UpAllNight91]

Hello. Thanks! The holes help the air escape during reassembly so the shock can be as fully bleed as possible.

[@GroovyVideo2]

the holes are a good idea - Thanks -

[@evo5349]

Used to practice on a sand track a lot and as the oil get hot used to change it a lot then a full service twice a year. All ways clean the chrome shaft as crap get stuck under the rubber bumper. Sand tracks heat the shock to high temp's which brakes down the oil.

[@UpAllNight91]

That's for sure. Sand tracks surely bake the fluid. Especially if its all whooped out with rockers and stuff.

Great video! I just bought a used 2019 yz125. And the rear shock is leaking bad where shock oil is runningndown the lower links, and the front aswell but not as bad as the rear. Feels like in sitting on a yoga ball bounching all around. Both shocks are M9 suspension. My question is. Are the Tusk, All Balls or OEM rebuild kits compatible?

[@UpAllNight91]

I have had good luck with all balls and also the tusk brand seal kits. I used a all balls on my YZ450 some years back and easily put 100 hours on it no problem. Some brands like yamaha dont even sell just the seal so we are stuck going for arftermarket seals when one give up.

[@BIFFAKA35]

I can’t find that “double D” socket anywhere. Can you provide brand and part number?

Awsome job👏 could you tell me how much psi do i need in the shock of a 2000 yz426f ? Thank you

[@UpAllNight91]

Thanks! Its pretty much the same for all the yz's since as far as I been around. 147 PSI is what they call for but I just round up to 150 and call it good. Thanks for watching!

@@UpAllNight91 great👍 thank you

[@carlmackenzie6430]

Hi up all night. I know this is a shock video but it's your most recent video so I'm hopeing to get your attention 👌. This channel is 🔥 may I say. I ride 2002 yz 250 apex head and 2006 yz 125 hgs system vhm head v force ect. My question to you is reed petals for the 250. I don't want to spend 200 on a rad valve or v force as I like the bike as it is. But stock petals are over 100. Is there a better alternative to stock petals ?? Hit me up mate. Thanks

[@UpAllNight91]

Hello, thanks man! And thanks for watching!. Sounds like that 125 is a screamer! On my YZ250 I replaced the OEM petals at 100 hours. At 100 hours they could have went further, maybe 130 or even 150 but I wanted to test and see if I noticed . I made a video on it if you check my older videos. I think it was like 80 bucks for a set of OEM ones from yamaha. If I was looking to save a few bucks then I would probably just grab the boyesen super stock carbon fiber reeds. They are basically just OEM replacement

[@carlmackenzie6430]

@@UpAllNight91 ye man she's a screamer for sure. Just keeps on revving out . I'm sure to check your vids man. Iv seen the pro series reeds in my area in the UK but for 05 to current. Mine is an 02. I notice yamaha reed set up ain't changed since like 01. All part numbers the same. Would u say the 05 pro series would work ?

[@carlmackenzie6430]

As I like the idea of ditching the reed stoppers. But don't want to take them off on stock petals . The pro series's allows us to do that

[@diegoalvarezgramuglia2944]

wanting to use one these shock on a 140 pound bike - shorten stroke to 3 inches - shorten Overall length to about 14 inches - shorten shaft and body some - will be a lot of work if do it - does kyb or showa make similar type shock but shorter ?

[@bryceharris9196]

I have a 2014 yz 250 2 stroke. Would a wr450 shock from 16 work on that machine interchangeably aswell? Please someone let me know some differences if any

[@UpAllNight91]

Hello. The 2016 WR450 shock will not work on the YZ250 smoker. None of the reverse motor YZ's shocks will work. You would need a shock from a YZ smoker or a YZ 4 stroke that was before they went to the reverse motor.

[@kellybrown6988]

When should you service your shock? Is there a number of hours till you do it?

[@keithalexander36]

40 give or take depending on your riding.

[@UpAllNight91]

Yup, 40 hours is a good starting point if your not sure. Extremes on the far ends can change that though. If the rider is slow, doesn't tax the suspension, and conditions are cleaner then service intervals can be extended over 60 hours. And if rider rips and gets it dirty then 20 or sooner. For me its 40. At 40 its just starting to fade when warm and I kinda know its due

Thanks 🤙🏽

What if my upper collar is seized solid?

[@TheSunnyTrails]

Best take it to a mechanic and ask if he can just get that part loose for you. Offer some cash

[@UpAllNight91]

Ouch thats a bummer. I have seen them get stuck to the point they take the threads with them when they are finally forced loose. Try soaking it in some penetrating oil and cross your fingers the threads stay intact

[@seamarsh3756]

Will shock and fork swap if say I own a yz250x and buy a yz250fx?

[@UpAllNight91]

The yz250 smoker can use the yz250f shock and forks from like 2006 to 2013 but after that things start changing on the 250f and the shock is no longer interchangeable and the forks are not either without also using the clamps and maybe even the front axle (not sure but would surely check to be sure)

[@seanevans5249]

What year bikes have compatible shocks?

[@UpAllNight91]

all the Yamaha smokers share the same shock size from like early 2000s to current. But yamaha 4 strokes has changed its shock size a couple times thoughout these years though.

[@adamzeller7249]

Would this help it stop leaking?

[@UpAllNight91]

No. If its leaking you will need to replace the seal where its leaking.

The shop wants $500 to rebuild mine. They can go …. Themselves. They said it’s a 2.5 hour job. I wasn’t born yesterday. No matter how slow I am it would take no more than an hour tops

[@UpAllNight91]

Hello. Some shops will estimate the longest it would take them to do the job if they run into "hang up's". So no matter what they get paid well for their time. if the shock is already off the bike I would say 1.5 hours is a more honest hour estimate.

[@blakemclain4379]

Wwhooooooo?

[@mxr248]

Dude don’t know why you are counting threads when all you have to do is just measure and write it down. A lot quicker than counting tiny threads. If it’s a 450 the psi should be 175 not 150… also ppl you do not lose oil from the shock going up and down nor pressure.. when your seals leak like they do on your forks and you see oil then you can be concerned. My son had over 200 hrs on his bike and no leaks and still has the same pressure..

[@donovanpiper320]

If you are so smart, why are you watching?

[@mxr248]

@@donovanpiper320 cause I came across it like all types of videos and watch.🤣 I also know ppl that work on some of the pro bikes as well. So that’s how I know what the psi is supposed to be! Plus Genius your seals are in your shocks and forks to hold the oil in oil doesn’t come out every time your forte goes in an out or shock. Obviously it’s noticeable when they go bad.

I do not suggest using lower nitrogen pressure to lower the bike. However it is safe to lower it through the spring adjustment some if needed. If more than that is needed then use lowering links.

[@ThomasBrock74]

Dude, I'm pretty sure you're supposed to measure the amount of shock oil you're putting in there. You don't just willy nilly pour it in there. You gotta measure what you're putting in. I may be wrong because I am no suspension expert.I've never done it myself.I always paid other people to do it because I didn't have the right equipment nor the gas to put back in it when I was done. I just don't understand how you can just pour it in and Willie Nellie like that. I know I'm forth. You have to measure that s*** in a measuring cup and then pour it in. But you're just dumping it in the shock. I don't understand how you know you're getting a level just right now. Maybe you're doing it right and I just don't realize it because I don't know what the hell I'm talking about, but I would think that you are supposed to measure that..

[@UpAllNight91]

No sir. There is no measured amount. You are to fill it and bleed out all air. Doesn't matter how much it takes.

[@ThomasBrock74]

Dude, it would be much easier to take a caliper and measure it.Hell measure it with a f****** ruler.If you want to it don't matter but it's a lot easier than counting all those fucking threads

[@UpAllNight91]

Honestly depends on how sensitive you are to changes. For me I dial my bike is so tight and I'm so sensitive that even a 1/16 of a turn on the spinner is a major change and is felt. I often will spin it even less than that for very minor adjustments in handling. Because of this I take the time to count and mark. I want to be sure its exactly where I had it before, not even a nudge off.
