TE/TC 4CS Issues

I'm doing 12oz. curls every night in preparation!

Again, we need to focus here. I am talking about 4cs forks. How many 4cs forks have you sent to them? I agree that Zipty does amazing suspension work but I stand by my decision to not gut a suspension just because they can't improve the design. As I also mentioned I may regret that decision but so far it seems like I made the correct choice. I'd rather sell my 4cs and buy open chambers than to devalue my investment but that's just me. It's nice to have different options and I think we need to focus on that.

When I was deciding what to do with my suspension, and who to send it to, I had to make a decision based largely on feedback from what other users have experienced on the different forums. Logically, most tuners don't come on the forums and tell everyone exactly what they do, giving away their proprietary info (shim stacks, etc.). Also, I had no opportunity to ride all the different tuners work back to back, so a guy has to take a leap and choose a tuner. The higher price that I paid to have Kreft work done was because I choose all of the options that he offers. A large part of that cost was the Huck valves which allow lower oil levels and increased bottoming resistance. I am well aware that the early versions of the 4CS comes with an adjustable bottoming device (which has since been changed), but everything that I have read about the Huck valve has been really positive and I wanted to give them a try. I'm really happy with the way that my Kreft stuff works. Is it worth the price? Well unless I ride the same type of bike back to back with all the other tuners stuff sprung to my weight, I really won't know. It's just opinions without that kind of testing.

Well put Zack. I also took the leap and paid for the works and I think our setups are nearly identical since Kreft uses MXtech parts in their 4CS setup. The only difference would be a slight disagreement between Kreft and MXtech regarding midvalving so they each make those themselves. Like you say, unless we can ride them back to back it would be impossible to truly comment on the results. It's good to see we have choices as the 4CS seems to be here for the long run to avoid the dreaded air forks! Maybe we will meet on the trail sometime and then we can swap bikes.

Here is a little video explaining the 4CS asymmetrical system I/we had installed. I hope this helps clear up some confusion and helps new comers to the 4CS forks make a decision on how to make their forks better.

Let's look at this way (positive vibes)--WP and the 4CS has created a huge aftermarket tuner business to support our sport and the motorcycle industry in general.

A lot of good ideas never pan out or on other occasions come back later when the technology is better. Take a look at how fast the Honda multi chamber air forks disappeared and pro riders went back to the known good set ups they had before. Remember the Ryan Dungey KTM air suspension that came off after it cost him a few races. Hopefully the 4cs will get lined out by those who stick with them and they will come lined out from the factory then a guy won't have to drop $1,500.00 after spending 8K on a new bike.

Another question is, since a suspension guy won't tell you his secrets how do you know you're getting back a true 4 chamber fork?

They are referring to the stock 4CS configuration with the caps blowing off. The rebuild claims to cure that condition.

Here's another video from 707 that I just stumbled upon. I wish I had seen all these videos prior to taking the leap, because I would have been a bit more confident doing so. This one explains the components and clickers better IMHO.

Reveille, thanks for posting that video. I've seen that before and it's interesting how Jeremy refers to the design of the 4CS as similar to the TTX. I'm only guessing, but I believe he means the design is like an Ohlins. Also interesting is that he considers the fork to be world class (with mods of course). I would love to try the open chamber conversion that is being done by other tuners. I had a Yamaha WR that I revalved myself with a DIY kit from Smart Performance and that fork ( open chamber) worked pretty darn good. I wonder how the 4CS is being made into an open camber? I remember some posts on KTMTalk that said all you needed to do is remove the seperator seal (the blue one). Seems like the advantage to keeping the 4CS a 4 chamber design and adding all the Kreft or MX Tech options is all the adjustability you have with high and low speed compression, rebound, and bottoming control.

I guess if you only end up with compression adjustments on the bottom and rebound on the top is how you would know you no longer have a 4CS fork. With the asymmetrical, you have 4 adjustments. Other than that, I don't know enough to tell the difference without fully dissembling the forks. I'm more concerned with service intervals on this new setup TBH. I hope it doesn't fade when the oil gets old half way through the season...

All I can say is WTF. If I am paying (for the s model) top dollar for what is billed as the top machine and I came to this forum and see I'd been shafted with a lousy fork, I might drive right back to the dealer and get a refund, if just for the principle of it No wonder corporate is pissed at this forum. The unvarnished truth hurts.

Uhhh. Last I noticed this was 2015. Bad forks come on low price point bikes and on high end bikes the good stuff is on there and if you are a weight such as me at 165 you should not have to do anything but break it in and ride. Adjusters flying out, jarring ride, etc... LOL. Don't get me wrong. They now own the market in new bikes, but doesn't anyone test products anymore (not the magazines - They are vehicles for advertising)? Maybe they should provide a build your own model where you can easily spec, like some other company, or I guess, as many do, pay up and suck it up. Not a fan of either method.

Apple has this model. Pay top dollar and more and get mid range parts inside. I prefer to spec. my parts and buy from a different company.

The above is why I root for the small manufacturers, who do sweat the details for the ones who spend their hard earned dollars.

That would be me then as I'm picking up a new fe 350 on Monday , I didn't expect to be pumping more cash into the forks on top of the price of a new bike , I'm going to wait until iv rode it before I make judgment as a few mates have the 4cs and like them .
Do the problems with the forks only affect the fast boys , or is is novice all the way to pro riders that are having issues ??

you don't have to spend big money to get these forks better. A basic shim shuffle will get them better, as good as zip, kreft or mxtech I doubt it but certainly better than stock.
only 13 models had problems with the caps blowing off and bottoming cone bush breaking. They were changed in 14 models.

what I struggle with (same with all forks and shocks) is where to stop, how good is good and cost benefit of throwing more dollars at it. I'm pretty happy with my forks now after a few shim shuffles but has me wondering how they compare to kreft setup, then how the kreft non huck setup compares against the heck setup....where does it stop

Again I stress don't just go along with all the intrnet chatter and get all hug up on it, these forks may be the best thing ever for "you". we all ride at different speeds, different styles, and different areas. ride the things and decide for yourself
