Went to the fox website for fork instructions for the oem fork on my 2012 sb95 enduro and they only list. 140mm travel fork in that model. Do I have that fork with the travel shortened to 120? If not, why doesn't fox list the 120mm version of the 34 float on their site?
The the fox service stuff can be confusing, but the info is there.
Most importantly get the info on how to remove the lowers and replace the oil.
If you're fork is a year old you may want to consider replacing the dust wipers and seals while you're at it.
Once you have the lowers off, to change the travel limit, you only need to remove the retaining ring at the bottom of the air spring and then gently pull the bottom of the piston down until you can see the travel spacer.
The travel spacer will just pop off the rod with firm pressure.
