Agreed 👍 better than shit house WP forks! 4CS, hahahahaha now changed into explore which is a 4cs re-hash as WP had heaps to get through! Twin Chamber was the last good WP mass produced fork.
Good instruction! My -06 YZ125 had a bad oil seal on the right side of the fork so now the replacing will be easy! I was a bit confused at first because I've never done this myself. So tomorrow I'll go and buy a new seal and start working.
Very helpful video. I've got a '05 YZ125 (crappy KYB AOSS forks) so I got on ebay and bought some '09 YZ250F SSS forks. Just showed up yesterday so I started the rebuild, and unfortunately for me, the free piston is already busted on one of the legs. Was going to drill them out to prevent it, but oh well. Ordered some Zeta aluminum free pistons.
Hi everyone. I watched this video and I have a question for it. Since I don't understand much English, I need advice on why it's drilling holes in the valve(6:40min) and where will the hole be down or up?
thx for a very informative video, just bought myself a second hand 05 YZ250f fork, oil on the outer chamber was less than 200 cc, I had to try to lower the for by 1 inch, put a 1 inch bushing in the inner chamber shaft and replaced the lower plastic spring guide with a shorter PVC pipe...going for 2 inch lowering next time. also..is carb cleaner okay for cleaning? your oil and cleaners are hard and expensive to come by here in Jakarta.
Hi Travis,exellent video. I just bought a yz450f with 40 hrs on it ,it had a bad fork seal so im doing the bushes and seals.This video was brilliant ,best yet.I got a question for you if you got the time. My yz is a 2011 ,do you think i should do the hole in the piston? Is this a design oversight on the KYB? I guess thats 2 questions . You have been a big help to an old dirt rider.
At 2:40 in the video you seem to be able to screw off the little aluminium nut off of the shaft. Mine appears to be seized on there. Have you had this problem, or d o you have any suggestions to get it off? I'm thinking of buying two nuts and locking them together on the end of the shaft to hold the shaft from moving.
Got any vid showing 03ish Yz250f rebuild? I’ve found a blue bumper that’s come apart as well as what appears to have been a round wire spacer maybe that came off near the stack for base valve.
hello my friend! i have an xt660z tenere 2008 and some days before i replace the forks and the wheel with forks and wheel from wr426f now i have to change the springs with stiffer ones because tenere is way more heavy and i'm 100 kilos. but i don't know what springs i buy.. what i have to check ,calculate or consider before i buy???
Wear your gloves when using cleaners/solvents. Hexane in that cleaner is bad stuff. Had a friend develop blood cancer and die because he never wore gloves as a mechanic.
Ted Paszko So you mean to tell me that this KYB company just didn’t know to do this and that these are the best forks that are still trying to be beaten since 2007 to this day and you’re telling me they didn’t know the drill the hole come on man
A documentary needs to be made about kayaba sss forks. Crazy how long they have been around and they are still the best you can get on a stock bike.

Travis I haven't even looked at my owners Manuel yet because your advice has been very helpful, thank you
Absolutely well done. A little more detail would be great but that’s your business. Appreciate with what info you have provided.
A pro at work! Can’t wait to dig into mine
Still relevant today. Just got my latest weapon, a 2024 Stark Varg. Same forks !!
Watched your video and was very helpfull in helping me service my forks. Thanks alot great job.

Excellent video Travis. I will be calling to purchase the DIY kit from you
Damn, you are fast! Impressive video, tnx for sharing!
So efficient!
Thanks man

Great video. What size is the inner cap tool. 32mm or 36mm thanks.
Great Video thanks for the help!

Hey did you succeed? I have the same issue..
Jerry LC I think I just used brute force. It was five years ago.
I'm doing that too, and add wd40 then wait, then do it again.. hopefully it'll be loose tomorrow morning

How must dose a revalve spring polishing cost ? And a good rear shock on an Aprilla rsv4
hello my friend!
i have an xt660z tenere 2008 and some days before i replace the forks and the wheel with forks and wheel from wr426f
now i have to change the springs with stiffer ones because tenere is way more heavy and i'm 100 kilos.
but i don't know what springs i buy..
what i have to check ,calculate or consider before i buy???
What size has the internal cap wrench?
Nice work! What vice is that?
Just a Yost 5 inch with Wilton Soft Jaws Order on Amazon
Will the hole drilled into the free piston effect the damping?
Hey Al Quida, get some Honda forks and wear out the seals. They will explode.....
Thank you
Doesn't pushing the rod out cause damage to the rod seal thus requiring replacement?
where can I buy this "do it yourself front suspension rebuild kit"?... Would be awesome if there is some vendor in europe who sells this.
I`m like "bittechslow"... Whay do you drill the piston?!
Good afternoon, this is the same procedure for the suspension of YZ250F 2008? Thanks!
+Igor Vinicius yes
Not sure but, i heard supposed to back out "cliockers" before doing this?
I'd consult your service manual on that step, most bikes should have some technical info direct from KYB for the suspension inserted in their manuals.
How fine is that file?
i dont care about spliting my case but fork work i cant lol
Wear your gloves when using cleaners/solvents. Hexane in that cleaner is bad stuff. Had a friend develop blood cancer and die because he never wore gloves as a mechanic.
Don't drill the hole.
The hole released presure to keep the plastic part from breaking
