KYB OPEN CHAMBER FORK REBUILD | Yamaha, Honda, Kawasaki 05 and older

[@michaellechnarjr6391]

Thank you. I had purchased a TTR 230 and learned quickly the suspension sucked. So I bought an old YZ125 front end to put on. The suspension needed rebuilding but I was trying to keep my budget low. After watching this video about 5 times, I did the first one while watching and pausing. Was able to do my second one on my own and feel confident enough to do the basic maintenance on them. Keep up the great videos

[@DanMX2112]

Man this makes me happy, this is exactly why I do these videos. Thanks for the comment and for watching!

[@JaxsonM22]

Thanks man, will use this to service my 1999 cr125 forks. Must be a pretty good teacher! I’m 14 and this all made perfect sense

[@DanMX2112]

Haha thanks man, and I hope to be, thanks for watching and you got this!!!

[@cbadnc9040]

Great video!!! Will be doing my forks this week!! Thanks so much!

[@DanMX2112]

Heck yea, you got this! Thanks for watching and new forks are amazing!

[@congwang2609]

simple and straightforward，without too many fancy tools，nice vid！

[@DanMX2112]

Thank you sir, and thanks for watching!

I havnt seen a video where someone pulls apart the valve and the rod. Valve has a staked nut on top. Rod end where the castle nut tool goes is staked as well to the tube. Other end of rod inside cylinder has a staked nut. If i feel either of those 2 components dont work properly then ill open them up. But theres a bunch of orings still left in my kit after i did the easy stuff. Either these parts are staked because their "replaceable" or to keep people out, or maybe they would come apart easy. Hopefully anything in those 2 parts arnt bad after reassembly.

[@DanMX2112]

I understand, and honestly, most of the time the valve stacks are fine as long as the oil isn’t contaminated. I have rebuilt forks before with dirt in the oil, how, not sure.

Salve .scrivo da l'italia video bello e completo, grazie mille. 👍

[@JasperJones-z2e]

Hi Dan!! I have 07 yz250f and is the exact forks in video. I’ve watched many videos to compare and catch consistency in the process, your video was definitely clear and simple I love the most how you didn’t go overboard with your explaining and talking you stayed on track lol definitely made it easier to watch. So I was going through the process and I’m having issues keeping compression on my innertube compression chamber when I disassembled the forks from the outer tube and replace the seals. I went to check the compression and they had lost compression so I took them apart re-oiled them, and attempted this with your video, as soon as I feel that I have compression and threaded in and then go to test it. It seems to lose compression and then all the oil spill out. I’m at a loss. I feel that it’s not me and that maybe there’s something else wrong I could use your thoughts.

[@DanMX2112]

Sounds like you are not sealing in the inner chamber. The piston in the inner chamber could be blowing by, or you have air in the bleed. Hard to say without actually seeing it and feeling the stroke. Idk man, I wish I could help, but this sounds like an air or sealing area issue.

[@DanMX2112]

Thanks for the love btw, I really appreciate you!

[@JasperJones-z2e]

Oops I meant this comment for your other video closed chamber I believe. I’ll star it ..

[@DanMX2112]

@ all good, I knew what you meant lol

[@JasperJones-z2e]

@@DanMX2112would installing the piston upgrade as you did instead of buying a seal kit for the inner chamber Suffice? I noticed that the piston comes with seals? oh and thanks for your prompt response. I wasn’t expecting anything that quick.

[@jacobwestcott4536]

I liked watching you stroke it!

[@scottswygert7165]

Great video. No one seems to disassemble the inner cartridge to get to those valves and O-rings ?

[@DanMX2112]

Don’t have many issues with wear on them.

[@pat_2693]

Hello,can you tell me the correct high for oil stand to do this without special tool i have to fill it and i dont know how high is it or how long was the iron you put in

[@StoneRacing]

Tive várias dessas lanternas, comia muita pilha e iluminava pouco, mas era o que tinha na época.

[@rickg9217]

yz250 forks went to 48mm in 04 I think. Great vid though ill need it when my 99 yz250 seals need changed !!!

[@DanMX2112]

Thank you sir!

[@nniilo1917]

Awesome video, thank you

[@DanMX2112]

Thank you, I appreciate the comment!

[@RRDfinland]

I lowering my forks kx250f 04 flat track (not proper way to do it but works) 3,5" = "8.5cm" on spring I need to put 4" =10cm spacer on somewhere on cartridge. Ive read forum they sayd to put spacer top of the piston?? I have picture of whole fork disassembly but i cant put it here, so you cant point out what they mean😅

[@DanMX2112]

No idea there, lowering forks are out of my expertise lol sorry man.

[@RRDfinland]

@@DanMX2112 no problem.. 👍

[@DanMX2112]

@KawasakiMotoX2T thanks for watching, hope it helped regardless.

[@elliotd4853]

Does anyone know where you can get one of the rubber bumpers, mine is completely torn apart and I can’t find them anywhere.

[@kristopherfrootloops6714]

Found mine on ebay. About 25$ a piece for OEM. Have to search the proper part name. May find a part number on Google 1st to help.

[@StickmanTV]

what is the size of oil seal sir

[@DanMX2112]

No idea on the specs, although it’s for a 46mm KYB.

[@StickmanTV]

thank you sir. do you have any tricks to make is play softer?

[@DanMX2112]

@@StickmanTV using a thinner oil will allow the suspension to travel at a faster rate, meaning plusher and softer. This is the only way until you get into springs and valving. It works great btw, go for it. Try a 3 or 5 weight oil.

[@StickmanTV]

is there any available spring for lighter rider sir? i tried 2.5w but still feels stiff

[@DanMX2112]

@@StickmanTV yes sir, go to Recetech website and put in your info to find the correct spring rate for your liking.

[@c4r5on88]

Not sure what's on my 09 kxf250 but hopefully it's very similar

[@DanMX2112]

They should be Showa 48mm forks. They will be similar to my other fork video for my KYB Dual Chamber Forks. Go check it out.

[@c4r5on88]

@Daniel Tucker cheers buddy will do:)

[@bikemancody2752]

"Pull out your rod." Haha, that's what she said.

[@DanMX2112]

Did she though? Lol 😂

[@NipatKerkardon-sp9hh]

How much oil do you put in cc? 

[@DanMX2112]

No clue, we measure using the fork oil gauge. Some offer a measurement, some offer a CC.

[@NipatKerkardon-sp9hh]

@@DanMX2112 thank you

[@chris929rr7]

its in the bikes owners manual. Also there is no single amount. they give ranges for example my 01 yz 250 is 130 stock but can hold 150 with adjustments made in 5ml increments up to 150ml or cc. this is used in conjunction with clickers to fine tune handling.

[@DanMX2112]

@chris929rr7 spot on man, most people don’t know or can even feel difference in a few CC here and there. I’ve messed with to and had a perfect setting for me that I felt was dialed in. Thanks for commenting and helping out!

[@main-maing]

Double like 👌

[@DanMX2112]

Thank you sir!!’

[@ericsiebert8189]

This should be the same for Suzuki’s as well

[@DanMX2112]

Yes sir, they also had this fork!

[@sevensi62]

I've done everything exactly how you have done only it won't thread in and get tight just partially threaded and then it spins everything even when I hold it. I have no idea any help would be appreciated. What I'm seeing shouldn't even be possible. I'm at a loss

[@DanMX2112]

The side you are holding in your hand, pull it tight agains the fork tube, and try again. Let me know, but that’s the technique, your putting it on a bind temporarily to get the end to tighten up.

[@DanMX2112]

Like make the plastic cartridge touch the fork tube.

[@kellybrown6988]

Same here, impact on center bolt and just keeps spinning. Other videos don’t even acknowledge this and take it out like it just screws in an out no problem.

[@DanMX2112]

It doesn’t, gotta put that baby in a bind and zip it!

[@DrKlausTrophobie]

My docs are quite good, everything is understandable. Just the "hold the cartridge steady" is not very helpful. So i was looking for a video, aaannd ... it doesn't show. 🥴 But works like described here. Pull the upper piston rod of the cartridge out of center. 👍

[@BrianPatterson-z8g]

These bumper forks are terrible even revalved. 🤯🤯🤯🤯🤯

[@DanMX2112]

Old technology, and yes they are some lame forks compared to the new SSS forks from KYB.

[@darrylnicholson1640]

I have the proper tool paid a lot for it. And it is absolutely useless.

[@DanMX2112]

Haha what tool and why? I find any PROPER tool used correctly makes the job easier.
