fox float air pressure??

[sketch96]

New to these fox floats after riding a polaris the last 20 years! Where do I start with air pressure? Book shows 90psi front and 140-150psi rear. I am 255lbs dressed. Riding a 2014 m8000 162. What about playing with the limiter straps? Any good info would be appreciated!

I'm 185lbs plus gear and beer and I had the best luck last year at 60-70 lbs in the front and I believe 165lbs in the back. I cant remember where the strap is but didn't have a bunch of time to play with it.

Ditto. Have no experience with Fox Floats. On a Poo 800 Pro for the last couple of years and have gone to the dark side. 2012 HCR 153, 205 LBS.
Any input would be helpful.

also wondering if everyone is setting them inside the shop or outside. Air pressure will change with temp.

No matter what pressure you decide do it unloaded. No pressure on the shock. Lay on side for fronts and lift track or on side for rear.

I might have made that mistake 5 yrs ago when I first had floats as well.

Do it out on the hill where you ride

 

[sketch96]

so 150psi rear and about 60 to 70 frt set outside in the cold?

and with shocks unloaded

I like my fronts on the softer side, 55ish if i remember right. My rear is 150

ditto the great thing about a float is that they are progressive so you can start soft on the front so you can side hill easier but they will stiffen up for the big hits

I set the pressure based on sag. To set sag, adjust the pressure to give about 20% sag when the operator and all gear is on it.

Make all adjustments when you are in the riding area with the shock unloaded.

This is why I dont post air pressures , I just play with them on the hill until I like them

Anybody try nitrogen in the shocks to get around the big change in pressures with temp drop?

At one time I found on the Fox web site not to use nitrogen in Floats

I think that most people don't do this because it takes away the adjustability on the hill. I'm not going to pack around my nitrogen bottle and gage set. Plus you are supposed to check your pressures every couple rides to make sure they are maintaining where you want them to be. Nitrogen shouldn't hurt the shocks if you did put it in there.

Yep. Pressures for propper sag are going to differ for every rider depending on weight and gear carried (both on the rider and the sled). Also the primary riding position. Someone who sits down on the seat more on the trail will weight the rear end heavier than someone who primarily stands.

Also, in my experience more sag tends to give a smoother ride on the trail, but it negatively affects handling in deep snow conditions. Sitting lower reduces snow clearance under the sled and lowers the center of gravity. The lower center of gravity makes the sled more difficult to pull up on it's edge.

start soft and work your way up. I would start around 70 pounds. If you put to much pressure from the get go the shocks will "pack up" and not work right and you will hate them. The sled will be like a bucking bronco. The standard floats are tough to find a happy medium. Add the evol up grades to them if you can spare the extra cash. as far as pressure changes they do not fluctuated that much. I did not ride my sled equipped with Evol-x for a month last year because my grandma was sick and I could not find time to ride. In that month they had had drop maybe 5 pounds. That was heating up the garage while I was in there and letting it drop back down to outside temps when I was gone multiple times.

Thanks for the info! I went out on my first ride and never even thought to check the pressures. Riding a polaris too long!! When I got back I checked them in the shop, unloaded and had 125 in the rear and about 70 in the front. Thinking the rear was probably 115 or so outside and the front approx 60. Probably way too soft for someone my size.

62-65 PSI in the fronts- try 140 in the rear

take your pump with you. adjust from there, I'm about 255 dressed out also. 09 M8-162"
