Hi, I have a 17 FC350 which I'm losing the front end on cornering. It seems to want to tuck and I can't steer it in slippy conditions. I've got everything set to manufacturers standard in terms of clickers and air pressure. I'm basically just starting out with the bike. My forks are set to the lowest line in the triple clamps. My race sag on the rear is at 100mm but being 17st/238 pounds I've had a 54nm rear spring fitted.
Am I better off adding more air pressure and less compression? Raising the fork legs a little? The forks do not feel soft enough in the standard setting when I compare them to my Showa spring forks on my RMZ.
I may think about a revalve in the new year but for the price it will have to wait until after Christmas it is not an option now. Having said that I have never ever had a bike revalved but I've always managed to get the suspension working brilliantly for myself.
I'm not losing any traction at the rear wheel with the stiffer spring either.
Thanks for any help.

What pressure are you running?
Also the aer48 fork will not feel as soft as an springfork, it may feel very stiff with recommended pressures but when riding it's still plush.
I'm running the recommended 154psi. I suppose I should up that psi because that is the psi recommend to work with the stock rear spring. So essentially I'm running a stiffer rear spring with the same pressure in the forks it's gonna sag front heavy. If I had sprung forks obviously I'd have changed the fork springs to match the stiffer rear spring. I need to have a play about this weekend. Apparently the forks are highly tuneable
The Shop
Set sag to 106mm, and start at 160psi. and go lower from there.
145psi is just to low, and to low air pressure will push the fork down in its stroke making it harsh + it will not bottom or be in the right part of the stroke for 90% of the track (the non-jumping sections).
The lower the fork starts in the stroke, the harder it gets for it to bottom since there is less stroke left to build momentum.
This can be demonstrated by taking a forkleg from the bike, push it 4inches down in the stroke, stay there for a sec or two and from there try to push it as far down you can in one move.
Then do the same with the fork starting fully extended.
You will be able to push the fork further down, the higher in stroke you start (with some limitations of course).
