These things are cool!
If you let all of the air out...this thing is slammed!
Great for radar runs!
I put the front end up off the ground and set the pressure to about 55psi.
When I set the sled down...the pressure goes to about 80psi.
I will try it there.
Wish we had some snow !

Thanks rtx thats what i need to hear,someone trying things that relate to my sled,i like the abality to lower it for racing.

When you check your pressure at 80 psi, were the pressures even on both sides? Sled weight varies from each side and wonder if its noticeable. I think this might cause confusion if some people get lazy and not take the load off the shocks to check pressure. As you can see I don’t have my RTX to play with yet. :itchy:
We had 60 lbs in the floats when we did the demo rides.

Ive played with mine on the Nytro took em to 100psi just to see what its goin do.

My dealer told me: " To get the sled to handle like a trailing arm machine put the fox floats at 15psi".
Now call me Mr. Skeptical, but that seems wayyyyyyy to low-and nowhere in the Fox manual does it say anything about running them that low. I would guess that it may handle good but also bottom out severely. Any one have any thoughts on this issue- we just need some snow to find out for ourselves?!?!?!
Also, my dealer talked themselves up a lot and basically failed on all set up details, so I am not taking anything he/they said to heart. :?

With running them that low, the sled would probably roll over on you, yet bottom out while going over a twig.

When I had the sled in the air....I set both sides to just under the 55psi marker. When I set the sled down, the two sides are different. It is hard to get and exact read on how different they are and here is why.
Before I read the shock manual, I set bothe shocks to 55psi with the sled flat on the floor. The sled was slammed and the a-arms were way lower in the centre than they were by the spindle.....the geometry looked terrible.
I later read that the sled should be off of the ground. I took another measurement and the PSI was at about 25.
I pumped the left side up to 54 psi and set the sled down, it then read over 100. (Keep in mind the other side was still at 25 psi when I set the sled down)
I put the sled back up again, and set the right shock to 54 psi. When I set the sled down, the pressure read in the high 70's. I then checked the other side and it was in the 70's as well.
I think it will be hard to get them perfect, unless you have 2 guages hooked up.
The shocks do not hold much air and every time that you hook up your guage, you loose some air because of the length of the hose attached to the guage.....the manual says up to 4psi....I think?

"When checking or adjusting the air pressure of the Fox FLOAT Airshox,it is important to elevate the front of the sled and unload the suspension to get an accurate reading of the air pressure of the air shock.Failure to do so provides inaccurate pressure measurements (up to 15-20 pounds higher of a reading) and can result in improper adjustments to the air bladder due to the faulty data.
Many riders do not understand the air sleeve of this design simply replaces the spring,it does NOT have any affect on the valving of the shock itself.Under the air sleeve is an internal floating piston shock absorber with a valve stack,oil and nitrogen charge.Adjustments to the air pressure on these shocks does NOT change valving,it only changes the preload and effective spring rate!
Most of these shocks will have about 50 pounds of air pressure;to add,for example,five pounds of air pressure,does not increase the effective spring rate by five pounds;it is more like a 75 pound rate increase.These shocks have been well accepted and they perform
quite well,eliminating most hard bottoming due to the force vs. displacement curve that provides an exponential rise in effective spring rate as the shock nears the end of its mechanical travel.Most of the complaints come from a lack of understanding the design and the affect of air pressure changes."
Keep in mind the Yamaha floats are a little different but here they are(mabey) probably refering to the Cat floats.
While at the local dealer I looked at a RTX and noticed some shock oil that appeared to be leaking from the floats on both sides,not one spot but all around the shock and covered about 3 inches below the seal.WT fudge :? .I noticed this as the sled was 3ft up on a display stand.
Do people(or burley friends) have to pick their sleds up on the trail to adjust shocks
?Will they?When you stop on the trail will one ski be in hardpack and one in softer snow resulting in uneven ski/shock pressure resulting in uneven addition or subtraction of air pressure from the shock?
Keep the pressure even and keep checking to remain in the area of Yamaha specs and the pressure where you like it is what I would do.This means putting some testing miles on the sleds and adjusting as things start to break in.Ride,test and tune!

The oil on the body is normal for a new fox float, its not a leak.

Interesting info Meirda...thanks
These floats will definitely be a change to the norm that we are used to. I think tilting the sled to its side will be the easiest way to adjust air pressure on the trail. Seeing that there is different weight per ski on every sled, I would imagine the readings to be off regardless on how flat the floor is so their will be no shortcuts checking pressure. Once its set, I would imagine it will be left alone till radar or drag races.
Mrplow, these shocks have went through allot of testing so I don’t think it will be as complicated as it seems. We had 60 lbs in the floats on our demo rides last season so that will be my starting point since I was happy the way they performed.
