    New question here. Old fork maintenence

    I just bought a new unopened 2018 fox 34. Since it has been sitting in a box for a year should I do a lower leg service on it? I am not sure if the oil goes bad.

    The oil does not "go bad." The fork is certainly not "old." Just ride it.

    You wouldn't necessarily have to do it, however, it might not be a bad idea. Often times, new forks (whether in box or on new bikes) have less than ideal amounts of lube on the foam rings and a little less oil than they should in the lowers.

    Up to you, if you want piece of mind knowing it is as good as it can be for brand new, drop them and service it up. Otherwise, bolt it on and ride it!

    I would. Honestly, many shocks and forks come dry. Easy to do and even easier before installation.
    It is the Right of the People to Alter or to Abolish It.

    I would let it go until the first service interval. Oil foam rings by storing the bike hanging from the front wheel or inverting the bike. No harm in checking though, and if you're going to do it, pull the air spring and clean excess grease out of the negative chamber.
    Do the math.

    A bored day at work sends the mind wandering. Just watching Finch with his grammar. After all he is one of the grammar cops around here.

    IMO, they almost always (but that doesn't mean always) put the correct amount of oil in there, but for very low-volume oil-bath forks, a significant portion is absorbed by the seals, the foam ring, the bushings, etc., it ends up being pretty skimpy and doing a service is often a good idea. An older fork probably has dried out a bit and will probably absorb even more of the original oil. The air-spring side is a fairly small amount, so if anything, that would be the side to usually service.

    Alright, OP service the fork prior to installation for peace of mind. Not necessary but a great idea. >bandwagon<

    Also they often pack it with too much Slickoleum and clog up the air transfer port. I would do a lowers service for sure first. I got a 2019 over the summer that had a clogged port.

    In my experience, Slick Honey itself is usually not viscous enough to clog a transfer port. The port is pretty small but a few compressions as the air spring is pressurized will clear it out, even when there's way too much Slick Honey in the negative chamber. There may have been a glob of something stickier that clogged the port.
    Do the math.

    Or maybe it became sticky sitting in a warehouse for a year. You could hear it being clogged with compressing the fork to that spot.

    I removed a few fingerfulls of the stuff and re-assembled, fork worked awesome ever since.
