First time KTM owner (23 350SXF).
Yesterday, I started working on installing the JBI diy kit. I just took the midvalve assembly out. The pic/video below is EXACTLY how it was installed inside the cartridge.
I’m curious, has anyone else had the nut on top of the mid-valve assembly completely back out like this?
I’m going to go out on a limb and assume this would have been adversely effecting performance.
My 23 350 was not like that when installing the same kit.. I’d think the fork would have zero rebound dampening like that
That's what it felt like when I hit a rhythm section 10 weeks ago. Things got western quickly, and now I have titanium plates in my leg and plenty of time to revalve the forks and find stuff like this.
That’s insane. I’ve had delta shims shift on one side before, essentially doing the same thing, but I still had rebound in the other fork. I couldn’t imagine that happening on aers.
I hope you heal up quick and enjoy the jbi set up. I used him for a few setups on my 350
That is pretty shit to say the least. Did you buy it new or second hand? Not revalved I assume?

The last handful of years of WP's have that nut staked solid from the factory. It seems someone missed that step on yours.
I bought it used this year with 11 hours on it. I’ve put 22 hrs on it this year.
Also, there were NO marks on any of the bolts indicating it had not been disassembled once.
Is something missing off of there? It seems like a lot of extra thread above the nut. I am not sure you will be able to stake it unless the nut is closer to the top of the rod. It is going to feel like a different bike when you ride it again.
The stake or peen that is usually on it is more of a machine press deal. I'm thinking the factory likely has a special machine that machines off any excess length and presses the the stem in one swoop. This pic is from the Ride JBI DIY kit install video.
It is definitely staked at the top. That’ll get ground off. For now, the nut spins freely up until the top but it won’t fall off.
Definitely a crazy find and big L for the quality control department. Looking forward to riding again in a few months.
Good grief. Just came across this on YouTube. This guy disassembled a new fork and the base valve nut backed out. Mine was the mid-valve. Looks like KTM must have laid-off the quality control team or quit applying loctite to save money. https://youtu.be/cHOuS8jnSCk?si=Fgplpdf2w94a1ipL
Yeah... going to have to start disassembling entire bikes before riding them soon. Piss poor craftsmanship.
I opened up a new ktm fork oonce. It had mixed up 6 aND 8mm shims, aND wwashers iinstead of the correct mmachined spacers.
They qquality ccontrol is nearly as bad as the aautocorrect on this wwebsite
I can change fork seals and swap springs, but have no absolutely no knowledge on base valves and mid valves.
Are those nuts that have backed off something that can simply be tightened back up and are then good to go?
It could be tightened up and have some decent lock tite applied. It is kind of whacky that it came like that with all that excess thread exposed.
