TE/TC stupid question which ktms came with open chamber forks?? and how hard is it to do a kayaba con??

Just putting this out there. If I were looking for open chamber 48mm wp forks how do I identify them and what years and bikes did they come on??

I think I came across a thread on KTMTALK or ThumperTalk where there is a guy is doing wp oc with sss internals.

Probably not really helpful, but my '14 FC250 has closed chamber WP forks. They feel similar to the stock YZ250's that I've ridden in the past.

KTM exc's also have open chamber forks 2009 upwards are the ones you want. Corey DS1234 or something like that off KTM talk is the man you need to talk too, he does SSS conversions cheap as and rates then pretty high

Fletch, option if you don't find the 4cs system to your liking. ZipTy Racing mod, basically Ty guts your 4CS and makes the top adjusters REB and bottom COMP with the addition of base valves, essentially an open chamber fork set up. Done and tuned by a real master- Ty Davis. I finally got the feel point I was searching for. But firstly why not break in the 4CS and play clicker and spring madness with them first. (we did lots of playing and adjusting before relenting and having Ty give me on my TE300 what he already gave LR for his FE350), so far since Ty did them I have added 10cc of 5w then 5cc more then 5cc more, now I get a fairly soft bottom on only very hard trail hits mostly from nose down BIG drop offs at slow speed, I even added some comp only 1 click...but will go back to Tys original setting.....

or you can go full factory style boat and have ZipTy install the Marzocchi cartridge inserts into the forks and get the best of the best (ZipTy race bikes all use this setup Ty's, Justin's bikes)

Halls did a front and rear revalve with stock spring rates. I would really like to ride the bike. Break in the suspension and see if it will work. I won't lie maybe I'm looking into the forum talk to much. I mean is it possible these forks will he great? I dislike deflection and or the feeling of near death when hitting a square edged object and getting pitched towards a tree.. If it were not 20,below 0 and the ground froze I could get this bike out and check it out! Truth be told I like my bike Kdx soft just a tish stiffer. I mean I already paid for this revalve.....never had to go on another forum for advice... Only other forum I look at is gasgasrider.org is it possible these forks will be fine or should a guy just skip the bs and do different.... How do you identify a w . Open chamber fork from the outside? What about axle size difference when putting the older fork on the newer bike? What's it cost to do the 4cs forks where they are open chamber? Or the marzocchi internals? I like the sounds if that at least...and I almost bought a beta rrrace edition just to avoid the wp componets...but I'm in deep so this chapter three Husqvarna must be made to work!!!

seek your own knowledge grasshopper. wait and test, then you can make any call you want.

I'm just a suspension tinkerer for the guys in my group, but I've got a guy running 4CS on his 14 300xcw Six Days who is very happy with them. We took them through 2 revalves cycles, mainly because I didn't yet know how sensitive or not they'd be to shim changes, then we convinced ourselves that one problem is poor flow into the base valve. Once we made a nice entry there things improved. And for the record, I'll be the first to admit that this is nothing like the mods Ty is doing. That's way more extensive and probably much more effective.

Another rider I'm working with has the 4CS on his FE350 Berg and we have not yet done the base valve flow mods. I wasn't convinced and wanted to try some other ideas before we got out the grinder. But I'm beginning to think there's something to that mod.

Interesting, pm sent

Yea. I'll ride and break them in with the halls revalve and if I don't like them mail them out.... Or I may just skip riding it and mail them to ty and just be done with it. When sprung.comes around the corner I'm not sure I want to be having down time due to the forks....
