TE/TC 4CS Issues

Check all of the factory bikes, even Jarvis's. I bet they are all "stock" with adjustable base valves. *smirk*

Well, after I wrote the first post, I shipped my forks to Zip Ty. I'm pretty annoyed with these 4CS forks. My last Husky was pretty similar in quality however. At least I haven't had to take the engine apart before 4 hours, or put on a different carburetor? My last KTM however was flawless. I put 430 hours on the clock, with just the regular maintenance stuff. I did revalve the suspension because my speed increased so dramatically in the 2 years I owned it. Oh well. I can't wait to get the forks back and get back to riding. Winter is awesome to ride in the northwest because the work projects have slowed down and the trails are terrible! Woohoo!

Pedro is Pietro Palladino the factory race field service rep/tech for Marzocchi, he is a genius of set up for both moto and in the MTB racing world. He is a super busy guy that works on top tier suspension stuff from MXGP to World Enduro motos as well world championship mountain bike set ups. Ty Davis has a direct line with "Pedro".

I can't wait for Rob to do the Jarvis School....

has anybody on the east coast used works enduro riders suspension on these 4cs yet? (W.E.R) drew is about 45 min from my house and hes basically the main guy to go too for amazing woods suspension around here.. im going to be getting my 2015 te300 soon and I no im going to need springs in it most likely right away. so I kinda want to have a game plan ready..

only reason im aiming on going with W.E.R is he rides the same woods I ride and race on and he knows the area very well and how to set up a bike.. I ride rocks and tight single track. (top 3 B rider most races)

but im also thinking about zipty based on the info on this site and it sure seems like they have these forks figured out

anyone got any custom stacks they are using? i'm trying a different set on monday, hope to get rid of some of the square edge stuff

I know I use to revalve my own OC and CC forks because I am extremely picky.... but the more complicated these forks get the harder it is getting.... let us know what you come up with.... I'm just worried that in the current format (4cs) you can move enough oil to make the action off road correct and also not over work the oil causing fade....

Must be me but the new Huskie I road felt pretty good. What's your bike doing, Mike? Drew is the man.

i don't have the bike yet steve. im just reading so much about these forks so im planning on getting them done befor spring

I was just talking to Drew and he's coming up with a plan for 4CS.

overall my forks aren't too bad, very harsh on square edge stuff which i'm trying to valve out

80km on the forks today, much better. Still not there yet but much better than before, will strip them this week and make some more changes and test next weekend.
I also plan on running a 2.5W (15cst) oil

So you guys have finally got 4cs. In the UK we were subjected to them on the Husaberg's in 2013. I had one of these bikes and found the first 4 hours of riding it wasn't that bad after this the forks felt skitsh bordering on dangerous. PDS bikes appear to have a high seat and with these forks being odd the handling was dreadful. That bike is now sold being replaced with two bikes: 2014 ktm 250 xcf and 2015 husky te250. The KTM I removed the 4cs forks before it turned a wheel going WP CC from a 2013 sxf 450. The rear shock is also off a sxf 450. For racing cross country events it fantastic. The Husky is still new and with 4cs. Having ridden the Husky for less then 4 hours the forks are not great but are way better then the Husaberg's. That said the Husky has a linkage rear. 4cs forks do not inspire me with confidence and with stock springs of 4.2nm in the Husky they should be super sensitive. I think the main problem is they blow through there stroke to quickly and do not respond so small-ish tree roots or rocks. Its disappointing the customers have to do KTM/Husky's RnD on these forks.

"It's disappointing the customers have to do KTM/Husky's RnD on these forks" You can say that again! I'm sending mine off after Christmas for some work.

My question is does ZipTy accept American Express gift cards? Haha, I got to $500 AE gift cards from work as a bonus this year. I know MX Tech takes em cause I used them last year but I think it seems ZipTy has these 4CS figured out pretty darn good. MX Tech is pricey...

Are these new 4CS forks really this bad? How do they compare to the stock wr250 forks from my bikes era (2000-2002)? I'm interested in possibly getting a new husky one day, but I'll probably wait a couple more years as they are a bit expensive, but everyone seems to complain about the front forks. I still really enjoy my ancient 2000 wr250 (it has 2001 forks with .40 springs and 5wt oil 120mm from top)

There seems to be a difference of opinions on this. I'm friendly with the local husky dealer and had the opportunity to try out a few models. It seems from what I understand that on the heavier bikes (FE501-FE450) they seem to work reasonably well but most complains are from the lighter bikes. (TE 300- 250's etc) Feedback seems that on the lighter versions they are harsher and less compliant. I have the FE501 and for my limited riding capacity they perform OK. On the test TE300 I found them a bit harsh but I initially put it down to not being setup for my weight, afterwards I heard others complain about the same thing....
From what I read here there are more issues with them in the 2 stroke tread, one of the suspension experts here probably can elaborate more.

I'd say they are on par with the old KYB's. I had an 01 WR250F and still use 03 YZ125 revalved forks on my KDX220 - setup much like yours....42 springs, 5wt, 120 mm. You can't beat the open-chamber KYB's for off-road stuff, IMO. I think for trail riding, enduro's and such lower speed endeavors, the 4CS forks may even be a bit better than the KYB's, once dialed in. They do take some time to break in and are a bit firm toward the full compression end of travel, but not spikey at all in the rough, choppy stuff I ride. Hmmm, I guess the best way I can describe the action is they firm up quickly, but not enough to feel like a spike. I think that the springs on my TE250 are a little on the softer side than I'm used to and that contributes to the damping taking much of the force - and I'm an old guy who weighs about 160 lbs.
