    Slight fork oil leak?

    Apparently I can't catch a break with little things on this bike, but that's half the fun, right? I noticed a little bit of liquid coming out of the holes at the base of the fork boot on my right fork. Should it be easy to pop off the boot where's it's attached on bottom so I can get a better look at the fork seal? I don't want to go yanking it up the fork only to realize its not supposed to come off and have to replace it. I should be fine riding around with a little leak for a while too, right?

    Yes – you can pop the boot up and take a look – but rub the leaking liquid between your fingers first – it might just be water.

    If it is oil, for it to start escaping the boot it’s more likely to be a serious leak – not a “little” leak.

    The problem with that is, with more oil in one fork than the other, the damping effect will be unequal, which will affect the handling under braking and bumps

    Rub it in between your fingers first – you might just get lucky ……

    ...and if you pop the boot off and it is more than just a little, you have 2 courses of action, however you still have to figure out how much oil you may have lost and replace it.

    If the leak just started, you may try cleaning around the seal (after dust cover is removed) with a seal cleaner. It's a thin hook like tool to slip in between the tube and seal and clean out possible debris causing a leak. In Moab this past year, I made one out of a Autozone rewards card and it worked. I had sand or something like it. I guessemated how much oil to put in, but I don't advise this, just something I did in the field environment.



    The second course of action is to remove and disassemble the offending leaking fork. It's much easier to do than to explain. Here is a great thread on how to change a seal: https://tw200forum.com/forum/technica...placement.html

    If you need more help, there's several of us here who've had to replace our seals and did it ourselves. Just let us know!

    Thanks for the advice! It honestly just looks like a little extra moisture around the bottom fold of the fork boot (the one with the holes in it, and the bottom on the fold directly above it), not a drip or anything. I'll check it out by popping the boot up when I get home from work and let you all know! That tool looks great Admiral - I'm all for the simple fix if it works, haha. Here I am thinking I got a good deal on this bike, and it's been nothing but little fixes since I picked it up! Still makes me grin ear to ear when I ride it though.

    If you ever do start to see oil on the fork, try the Seal Mate first.
    After the Oregon dunes my WR had oil on the fork.
    I used the Seal Mate on both seals and it fixed the problem.
    Check out their website for full details on how to use.

    Well I have now confirmed that it is indeed time for a a new fork seal. Luckily I can just take the fork off and bring it to my local shop to get a new one put on. I know some folks have replaced their own with some home made specialty tools, but with my limited toolset I think it will be best to actually take it in. Ah well! There's always something with this little bike, haha.

    All you need for speciality tools should be found right at home!

    Easy peasy fork removal tool


    Choose the best tool for the job


    After all, you have choices!


    Of course, I kid. If you don't have the time or are not comfortable with the job, no harm in taking it to someone who can or the job could end up looking like this.


    Hope you're back up and running in no time!

    Have you tried running a thin piece of plastic around the seal to see if it just has a piece of dirt in it?

    This ^^^^. Make that same tool out of a 20 ounce plastic soda bottle. The contour of the bottle matches the forks. This is the problem most of the time. It's so easy!!!! Please try it before you send it out.
