I know it can be done. I ordered the travel-reducer spacer, 2 crush washers and a bottle of fluid direct from Fox. But I expected somewhere on their site I would find some type of help on doing the work. I've never taken a Fox fork apart. I have a 2009 F100 32 series fork, going down to 90. Anyone know of any resources online? I was hoping to do the work tomorrow and can't call Fox until Tuesday at least. Thanks...it's a long shot, I know.

I finally found the disassembly instruction on the Fox service site. But one thing not clear to me is if I have to take the lower legs off the stanchions. The Fox instructions start with the legs being off. I am hoping I don't have to take the entire thing apart just to reduce the travel. Can I just start on the left air-spring side and leave the right side alone?

No, you don't need to remove the lowers. Yes, you can leave the right side alone. Good luck! Once you dig in, you'll see how simple it actually is.

That's good to know. Still, Fox should have a specific area on their site just for doing the travel reductions. Maybe I'll do a quick youtube video of the procedure for others to find. Without watching the clips on Fox again, It seems I need to let the air out of the left chamber, loosen the bottom thing, take the top thing off, drain the oil somewhere along the line, and pull the shaft out, put the spacer on, and reverse. I'll have to find out how much oil to put back in I guess, that must be somewhere on fox.com. Thanks.

Well, now I have another question. I found the instructions for removing the air-chamber side assembly. Upon re-assembly, it shows a "pillow pack" of 5cc float fluid being put back in to the top. The fox guy sent me a big ol motor-oil size liter of 10W Green fluid. This can't be the same stuff, the pillow pack is clearly a blue color. I told him what I was doing, and it was he that said "okay, you'll also need a new crush washer and fluid"...did he send me the wrong fluid? The chart of fluids for F-series forks says the only fluid needed for the air chamber is float fluid, but the instructions show two types of fluid.

Now I'm totally confused. This is one last ditch effort to get the correct info before calling Fox tuesday. man, I really wanted to to this today while I have the day off...

oh well.

Fox changed their fluid requirements for 2010. They found no performance difference between the 5w and the 10w. If Fox sent you 10w, use it.

So the weightwas the only thing different between the various fluids? That makes sense. I have to find a measuring thing for the fluids. Auto parts store maybe?

The Float Fluid at the top of the piston is quite thick...I and a number of other folks here have used regular synthetic gear oil. I know of people who use the fork oil (the 10wt stuff they sent) there...not sure how much of a difference it makes, but the fork oil is a lot thinner.

I use a big syringe thing for measuring and injecting the fluid...I think it was sold as a way to measure out 2 cycle engine oil at the right ratio. I think it's...50cc?

You might be able to pop the air piston out without spilling any fork oil if you keep the fork horizontal...I've done so a number of times. A few drops do spill out, but it's not a big deal. The Float Fluid all has to come out, though.
