Hey man, just wanted to check in and say that this video convinced me to tackle my rebuild myself. I got the Pivot works kit and a Racetech spring for my weight. Went and got it charged with nitrogen this morning. I did find that in my shock, it already had aftermarket valving and that friction seal that came with the kit was too wide for the racetech gold valve. I trimmed it down to fit and havent had a problem. It looks like your KX videos are kinda old now, but PLEASE dont take them down, we still need these 99-02 specific videos. Thanks again man!!!

Noticed if you put your valve with seal installed in the freezer, it shrinks up good! Thanks, for putting out content for kx250. I have a 2000 kx250 and your info is great! Just bought your vid on top end and worked great for step by step tutorial. Another 70 hours before the bottom end is ready for a rebuild. 🤘🏻🤘🏻🤙🏻🤙🏻

Thanks! Click on blog post in vid description, I list the PN & source where I buy my parts from.

Thanks man! This detailed video gave me the bump in confidence I needed to take this on myself.

Bleeding the air out of the shock with a syringe works really well! I went down to my local grocery store and the pharmacy department gave me a couple free oral syringes that fit perfect in the bleeder port I just rebuilt the shock on my 2005 yamaha r6 a few days ago, installed a race tech gold valve... This was my first time ever servicing a gas shock, it was time consuming but not as difficult as I first imagined... It was such a good feeling to have the shock all put back together, clean and ready to ride. Just wanted to thank you for making this video definitely picked up some good tips that made the job easier...

Cool thanks for the feedback.

Thanks for the long detailed video man. My shock has a bleeder too and I used a syringe like you. Good idea!:)

it would really, really help you with the spring removal if you washed shock before even trying to service it.... all the dirt from outside is now inside :)

The best KYB shock rebuild video here. Thanks!

Matt, another dynamite video! my CRF rebuild was perfect thanks to your previous video and this one also worked great, Thanks

MatthewMCRepair Matt, I seen in Rocky Mountain ATVs video that the bladder requires nitrogen. I kinda skipped throughout your video, but did you use just plain air and did it require a certain PSI?

@HTMR

9 жыл бұрын

Gorbachev I took it to a shop who filled it with nitrogen to 175psi for $5. Don't use plain air.

Try working the shock to rid any trapped air bubbles. Leave bladder out and also the shock cap at other end. Use the bleed hole at end of procedure.

Best way to keep the valve stack in order is use a Philip screwdriver and slide the stack onto it. Plus cleaning the shock before working on it helps keeping debris from getting into places.

Cool. I'll check them out.

Thank you for posting this video it was really helpful

Very nice video, best I have seen so far on shock rebuild. Where did you order replacement parts from?

i highly recommend to use a shock seal head driver ... you can find some at $35.00. I use the K-Tech one ... and it goes smooth without risk of damaging the seal. Good video !

Nitrogen is more stable as it heats up and contains no moisture. More consistent through temperature changes.

You have a video for the shock that has the remote reservoir that’s attached by hose? These don’t have bladders but a internal floating piston. Would love to know how to actually rebuild a shock with that setup.

Hi thanks for the video, I'm trying to do this myself, I was wondering what the purpose is of filling the bladder with air while filling with oil is, and if it is necessary to do or not? Thanks

Does the bladder have an holes in it? Did you bleed the shock?

Hey brother could you tell me or help me to see if that repair kit serves my rear shock of wr500zd

great video. thanks for sharing. the shock on my 99 xr250 is really soft. spends more time in air. no oil leaks or anything though. You think a rebuild like this should fix it or is it another issue in your view? Appreciate any pointers before i strip it down.

Is the shock really springy like a pogo stick? That would mean the shock is not dampening at all.

42:45: Does the tightening torque of the nut affect damping characteristic, is it important to maintain the exact torque spec to get the needed damping, so the nut torque is some sort of adjustment or doesn't matter if I tighten it a little bit more?

nice video.I am rebuilding my shock and i have a question.When i put the blader in and fill it with air i see bubbles coming from the other side.Is that normal?

How much different is the showa shock from the kyb

Do you know what oil viscosity need to have for the rear shock?

Top, muito bom!!!

so you can use air if you check it when the temperature changes? I'm working on a 1987 KX500 KYB shock, does anyone know why the bottom damper adjustment is stuck. I had the adjuster out, its a bevel drive gear that runs through the rod, but no was to free it up??

How do I do this if my kyb off 98kx has no bleeder bolt?

hey matthew, 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 52:40 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

@HTMR

Monica Armentano The piston allows for fluid to pass. Just fill it up to get rid of all air. You want a bit of fluid to spill out.

Do you recommend changing the schrader valve or bladder with a regular oil change?

just what i thought, ya got nothing, compressed air is a liquid that boils off when it hits the ambient air, like propane tanks for grills its LP or Liquid propane as thats its state when compressed. Do some reading and stop making yourself look a fool by posting your ignorance

At the 1hr mark when you pushed the rod in and then put air into the bladder the rod should have extended back out on its own and it did not. You still have air in cylinder

I suppose it is needed so the oil wouldn't compress bladder. so you pour in exact amount of oil needed.

Stick a long philips head screw driver onto the end of the shaft and remove your valve stack sliding it onto the screw driver. The zip tie method your trying to use just looks difficult and time consuming.

Hi Mat. Thx for the video. I did everything like you did but have huge problems with the shock. at 51:38 in your video, you can push your rod down / up quite easily. I cant. Its such a huge resistance - its possible but with a lot of force only (definitly not like in your vid). Do you have any idea what could have happened? :( Btw I am not using real shock oil. I used Maxima 5w Fork oil (I am quite low on budget and still had some Maxima oil left). Could this be the reason? The viscosity difference compared to shock oil? I am totally sure I did everything right (like you in the video)... I completed the shock and also did the bleeding process - but still its VERRY hard to push the rod inside and it wont come out again. But I dont have the nitrogen in yet... only air with ~60 psi. Greetings & thx again.

+MatthewMCRepair hey Matthew! I gave up on this (actually the first time - I even disassembled the engine but maybe I have not talent with shocks). I dont know what exactly went wrong. When I put the rod inside I couldnt move it up or down without extremely heavy force. This went so far, that when I tryed to disassembled the shock again (because obviously something went wrong) I couldnt slide out the rod without opening the bleeder screw and letting out the oil first, because it was so sticky inside. Finally, I gave the shock to a service specialist. This was a good idea, since it was very cheap for me because everything was already disassembled and replaced (the seals) and I also needed the shock oil and the nitrogen charge. So this guy could do it for me for only 70 euros (all completely) which is ~80 $. He also noticed an huge scratch in the rod. First he wanted to sell me a new rod for 220$ but I told him that this is no option, so he grinded the whole rod and its looking like new now :) So I am very happy. Next time I will go there again... definitly worth the 70$ dollars (it was +10$ for the grinding). But thank you for helping / assisting. Like always, your videos are the best resource for a DIY men like me (except shocks now lol) and it helped me disassembling the shock which saved a lot of money. Greetings from germany! Mike

In a shock rebuild whats the purpose for nitrogen? Why can't you just use air?

Hi Mat... At 13:09 why are you grinding the top of the bolt? I have the same shock and I’ve tried to unscrew this bolt without grinding the top of the bolt... after make a little force it’s released. I stoped this job to came here ask you this! I´m afraid to complete unscrew and damage something... (I'm not sure if it’s the screw that’s rotating or the shaft) thanks..

thanks friend this is realy help me

The guy knows the steps though he has a couple out of order that make disassembly easier than what he demonstrates. Otherwise he is a bit of a hack. I can see many damaged parts from his methods. There are a couple inexpensive and/or home made tools that make things much easier than what you see in the video.
