I beg for the mercy of the court! I am reposting this inquiry from the Stock Suspension category as there is not much activity down there!
My Fox floats on my RTX came with 95PSI in them. Reading the recent SnowGoer article (which talked down the handling of the RTX) I am curious what the servicable range is on these shocks. The manual that came with the sled says to start with 70PSI and adjust in 5PSI increments. Dealer set it up at 95PSI. SG article indicates that their demo was at 80PSI and felt a lighter rate would have improved handling.
My questions is this...how low is too low and how high it too high?

What I like to do is put a rubber o-ring on the lower shaft that way you know how much of the travel your're using up and adjust accordingly.Or call the Fox tech line they should be able to give you some numbers as well.

A few bits of advice:
The Fox Floats come delivered with 70 psi, obviously this will vary with temp.
Make sure you check psi with the shock fully extended, lift the front end off the ground.
Recommended adjustment range is 60 to 80 psi, so 70 is a good psi to start, that is production spec.
10 psi change over 100 F of temp change.
Set the pressure when it gets cold out. If the temp changes more than 30 F, the pressure should be reset.

I'am sure the maximum psi is 150, states that right on the shock body no?

My buddy wieghts 145lbs not including gear.. and has his shocks on his 05 F7 set at 60lbs.. so i would say you will need atleast 70lbs for the RTX..

I usually run my frt suspension really hard....I will keep my RTX as low as possible to keep the ride height low.

Dealer told me that in order to really get it to corner well, without inside ski lift I should run them with as little as 15psi. This seems way to little. I have to wonder why they had 100psi in them when my dealer also said that they set it up perfectly for me - thats funny I dont remember telling them how much I weigh.

You should check the static sag first with rider and clothing.Then go from there,same with the rear.I thought that Yamaha was supply instructions on how to do this for the people that don't no how?.

On our demo ride last season, we rode the Apex GT and RTX back to back. To be honest I did not notice a big difference. It did seem the front end felt softer on the RTX, but definitely did not feel tippy and I really got to honk the RTX in the twisties. My understanding is we had the shocks set at around 60 lbs. I would say 15 lbs is to low. (I weigh maybe 210 with gear)
As viper34 says, make sure the load is off the shocks and fully extended when checking pressure. Also keep in mind that the front end weighs different on each ski so I would not check pressures comparisons for a ball park figure while the shocks are compressed on level surface.
