TE/TC 4CS Issues

I really need to ride with these forks. Ratings seem to be all over the place...confusing to say the least.....

Without riding the bike I can't make any judgement calls. What works for one guy won't another. I rode a stock 09 yz 125 and really liked those forks...

You say this like it is a bad thing. My 300 lbs is usually well suited to test stock suspension and the 6+ inches of sag make it a easy rider. I keep thinking about heavier springs, heck I even bought a set, but then a buddy wanted them so I gave them to him. I hate to admit it but my clickers are stock as well just like they were on the last bike. I guess I am just not picky and happy to just be riding. Heck I even have suspension tools to change oil when I need to do that. Maybe I am just scared of going to fast with good suspension and this is my way of keeping the spped down.

exactly. everybody likes something different when it comes to setup. ill ride it (should be January when the bike comes in ) and see how I feel on it. if I don't like it ill send it out to W.E.R ( drewsmith) or zipty

not sure if trolling or not but 300 lbs is way to heavy for stock suspension. You would be riding way down in the stroke, OEM gives you 300mm + suspension travel, springs hold you up so this is possible, 300 lbs would greatly reduce the available travel and make things harsh.

my mate who I rode with the other day hadn't played with anything before believing the shop would have set it up right considering he bought it new and they would know what to do being a dealer.
Sag wasn't even close and he is in the target weight range, rebound fork clicker was all but 2 out, forks were uneven height in the clamps and was wondering why my identical bike doesn't have the headshake like his does, I wonder why that might be.....

many people don't know how to diagnose what their suspension is doing right or wrong, start with the correct springs for your weight then just go out and ride and play with just one setting till you understand what it does and what it does when it isn't correct.
set clickers at recommended standard settings, then adjust that setting up 3 at a time until it does something wrong, then go back to standard and go down 3 at a time till it does something wrong, now you should have an understanding of what too much or too little damping does to that clicker, repeat for the other setting (comp or rebound).
very easy to overthink suspension

you suckers probably don't want him on proper spring rates....after those props sounds like the big guy will do some ego damage (hahaha) if handed a proper set up machine.....
I remember a trail ride we did with Tripes in Mex. when he still got out and rode, he was then in that 300+ range he was on a clapped out old CR250 maybe one of his old race bikes(??) the guy smoked 99% of the riders on that ride.

Here's what Stillwell Performance has to say:
We have been testing and tuning on the 4cs forks since they were released on the 2013 Husabergs.
Since then, the fork has been through 5 different revisions, yet the same fundamental problems exist. Exhaustive testing and customer feedback tells us the fork has these issues:
-Rides low
-Harsh in the initial stroke
-Spikes on square edge hits
-Too fast of a transition into the midstroke
-Will bottom on big hits too easily
-Rebound adjustment is limited
-Rebound problem on over 50% of the forks we see, creating a pressure balance problem that can blow the rebound adjuster off the top of the fork
The bottom line-the fork is oil starved. This is NOT a midvalve problem, the midvalve does flow plenty of fluid. The issue with the fork is oil starvation in the very initial part of the stroke.
We have designed Pro Valve pistons that allow the fork to flow in the critical first 4 inches of the stroke. This additional flow gives us valving options not available with the stock pistons.
Think of it like this-if you wash your truck with the hose nozzle only halfway open, you limit your ability to get the job done. However if you run the nozzle mostly open, the flow is much greater and you can then fine tune the spray.
We are essentially doing the same thing in the 4cs fork. This mod, along with our base valve valving, midvalve mods, oil and spring changes (where applicable) gives you a best in class result for your 4cs fork.

If you read virtually any tuning company's claims for their products or service (goldvalves, for instance) they all say basically the same thing as Stillwell has, more or less about any fork out there.
What I don't understand is why wouldn't white power be able to make similar changes, engineering-wise, when they have the money, the engineers, the test riders, etc., etc. ...? Or is the issue more about individual riding styles, general use types, speeds and setup? As I've said before, my TE250 forks are not perfect, but are not "harsh on initial stroke", they do not "spike on square edge hits" (which is everywhere I ride) and I've yet to bottom mine, even on larger jumps (not motocross tho'). But I don't ride much high speed stuff.
The only thing I've concluded with my setup (I'm 165 lbs) is the spring rate might be just a tad soft for some situations which allows the fork to travel too deeply into the stroke sometimes....but still not a real issue for me. It is possible that a more progressive compression damping action could clear that issue up, meaning more gradual increased compression as the fork shortens but still having light high speed compression for shorter travel hits. Does that make sense?

Interesting to see Stillwell in a round about way claiming Krefts mid valves are wrong yet claims the fault is with the first 4" of suspension travel and main benefits can be seen from modifying the base valve rather than the mid. Isn't the function of the base valve purely to flow the oil from the rod and prevent cavitation or have I got it wrong?

Horses for courses, some fokes are having great success with mid valve mods and custom pistons and others like Stillwell are having success with basevalve mods and custom pistons. My forks have stock mid stacks, heavier rebound and a bleed to compensate for heavier springs and custom base valves (softer LS, stronger HS) and check valves swapped and they ride nice and high and are plush. Only downside I see is they don't have rebound adjustment capability anymore.

More than one way to skin a cat

I just really like to ride and going warp speed isn't really a goal any more, but I do like to turn it once in a while.

Well, I finally got my forks back from Zip Ty after a month. Seriously, they had them a month? The forks work really well. All of the weirdness of the forks is gone and I can push really hard now. If you ride 2 to 3 times like me you had better find another shop to work on your gear. I missed 2 races and a bunch of rides. The longest I've waited to get forks back from any other shop was 8 days and they were super apologetic and let me know that they had some setbacks. I even called in advance and made sure they had time to get me in. They said the longest I would have to wait would be two weeks. I thought that was a bit excessive, but maybe my expectations are to high. I really don't know what was repaired, or if the damaged fork cap was replaced, or if the trashed dampening rod was replaced or just what was done. I'm just really hoping that if the parts weren't replaced that they don't fail in a critical situation.

silly you for paying and not knowing what work has been done.
4 weeks wait is pretty ordinary, how much was it?

No build sheet?

I was going to wait to post until I had a chance to ride my bike but...
I sent in the kyb's off my kx500 aluminum frame and it took about 5wks with shipping which was 1 1/2 wks. I was in touch with them through the process and every time they were very nice and helpful. I knew I'd have delays due to Christmas and new years which I'm sure added a week and it was my understanding they lost some help over this time which slowed things down. Now that being said they had three pages of parts that were put into my suspension since the person I bought it from apparently didn't know what suspension service ment. In my case they went above and beyond what I had expected by basically micro surfacing the forks to get all the half worn black coating off since I wasn't going to dump more into them to replace the coating, they also hooked me up with a colored rear spring that I really wanted and to top it off just sitting on it and cycling everything it feels super plush. When I do get some time on them I'll report back, I did miss a race but I knew there was a chance when I sent them out. I will send my 4cs to them but I'll do it knowing that it may take some time, it won't be as expensive as all the other guys, and they will be better when I get them back.
You can only usually get 2 of the 3- Fast, Cheap,good work

I deciced to drop my suspension off at MX-Tech, which is local to me. He's the one who solved the riddle to the 4CS forks. Everyone buys his parts to rework them so I'm headed there tomorrow. Looks like $700ish...Ouch but I'd end up paying the same with shipping sending them off.

You don't get to talk to anyone who is doing the actual work on the suspension when you call. The last call I made was just to tell them to send it back to me. But, they told me it was on the table torn apart and it would ship in the morning. The whole thing was weird really. I had EVO do my suspension on my KTM last year. I called them, they told me not to send my suspension for 3 weeks and to call and make sure that they were on track before sending it. I called them after 3 weeks. They said, "yes we are on schedule." I shipped the suspension on Monday. They called Wednesday to make sure that we were on the same page for valving, and I had my suspension back by Friday. They are only one day away for shipping, but that's still 3 weeks faster. Oh well, live and learn. Really they would be awesome with a little bit of scheduling and communication. Maybe they are just taking on to much business to keep up with everything. I had already purchased springs, so the cost of the work done was $275. That is super cheap for 4CS work.

I just recently spoke with john at zipty pertaining to my forks. I explained the weather conditions and not being able to ride the bike at the moment and told them jay hall had revalved them. Sounded like 180$ gets them where you adjust the rebound on the bottom. He claimed even if they didn't change the valving doing there mod would make a huge difference and they could look at the stack while it was disassembled. Need to give jay a call and get his input. The month seems long and that's why I want to get this issue resolved before race time and not be dealing with not being able to ride the bike while waiting. I'm working on getting a front wheel so I will have two sets of wheels. Race and practice. And contemplated the entire front end including wheel and brake assembly off of a yz 125 . (Kayaba sss) just want them to work right.....PS. They seemed very good over the phone...anyone know the cost of the marzocchi inserts and good and bad?? Anyone seen any 48 mm zokes for sale...if the gasser were lighter bi probably woundnt even have a 4cs fork...lol
