standard location is second line on forks. I like them there.

As mentioned, I use the standard clicker settings mostly except less HS compression on shock.

Any thoughts on where to run the forks in the triple clamps? I have them level with the second line at the moment.

I swapped to carbon front brake pads too. I like the power of my oversized rotor but combined with the stock Brembo pads it was super-grabby.

I just purchased a 16 350 xcf.
What did you end up finding worked best for you in regards to suspension set up and gearing?

Thanks.

I'm running a 12 tooth front sprocket for off-road with the stock chain and 50 tooth rear sprocket. Not ideal for chain or slider wear, but at least I can get some use out of the stock stuff.

I'm pretty happy with Dobi's recommended 103mm of sag, the 15ml less oil, and no spacers in the forks. I'll have to check what clicker settings I'm on these days, but I added some rebound and took out some compression.

I bottom the forks pretty good at times on the moto track now. For moto at least the extra oil was better, but it's a pain to take it out and add it back. I've had some pretty rough landings when I don't quite clear a jump...

Sadly the 4CS takes money to fix. I have been riding/hating them since 2013 on first a Husaberg and have tried numerous re-valves, tricks, etc., ridden many other bikes and tuners stuff and had never been blown away by any of them. for 2016, I have worked a fair amount with Ken at TNT Suspension to come up with a set up that I find hard to bottom and when I do it isn't that wood on wood clank that comes with the stock stuff. They will never be a yamaha fork when it comes to bottoming, but I believe that my forks are better than a stock yamaha in the first 2/3 of the stroke.

The key to any bike is getting the springs right to get good sag. The second part is to ride the wheels off it. The fast guys can still run fast on crappy suspension.

Thanks for the advice.
I will start with a 13 on the front and some basic suspension settings and see how it feels.

Resurrecting my old thread to post some updates. I tried Alex's recommend 2.5wt oil when I changed my fork seals the other day. Works good! :thumbsup:

I'm able to run a little higher oil height (though still 10ml less than stock) without the compression spike in the midstroke. I have a ~40ft jump that lands onto flat ground. I purposely landed level instead of rear first to see how the forks would absorb it. Still didn't bottom. I haven't tested on singletrack yet but my first impressions are promising.

I also experienced some episodes of headshake ripping across a gopher-mounded field, so I bought and installed the SXS damper mount I posted earlier in the thread. It's significantly harder to install than the old version... but very clean setup once done.

What oil height are you running and what is the stock oil height? I never did find a spec in the manual or simply missed it.

And to clarify are you running 10ml less than stock or 10mm lower?

My recollection is that I used 100mm of air gap, based on what I found on KTM talk and the race tech website. It's not listed in the owner's manual.

Then, recalling that it was easier to add oil than remove a precise amount once the forks are mounted, I removed 10ml with a syringe while the cap was off. I didn't measure the resulting air gap.

Edit: I should add, not all 4cs forks use the same air gap. Some earlier models spec'd as little as 65mm.

I got a settings sheet from my dealer on the 2016 suspension. I was going to post it until I read the warning on it about not distributing it.

Stock Fork settings are:
Air Chamber (no oil between inner/outer tube) 70mm
oil capacity 670ml
Spring Length with preload spacer 475mm

I think the rest of the items are in the manual

On my 2016 350XCF I ran 65mm oil height and 4.2 N/mm springs
