    I had my tires replaced and now I have notice that I am leaking a significant amount of oil from the top of the gaitors. Coincidence? Or should I contact the shop about it?[​IMG]

    I'm having trouble understanding how a shop changing tyres would result in leaking fork seals? :huh

    :rofl Never worked with customers? It is always the fault of the guy you paid to work on it last. :1drink

    Ok OP .. you should where the oil is coming from! It could be a break line ... :eek1. Please check before you ride it.

    =========
    If it is the break line .. then is it a junction or has a line worn through? If the tire has worn through the line then ... If a junction .. it could have been flexed if the break calipers were not supported if they were removed from the legs when the tire was replaced.


    =============
    If it is from the fork seal .. then you can try cleaning it .. sometimes a bit of dirt can become trapped between the seal and leg ..

    When you remove the wheel the fork lowers drop to full extension. They may not have been there for quite a while. The seals run over surfaces they have not run over for a while, including dirty or damaged surfaces. This can provoke a leak in an old seal.


    The fork legs should be aligned when the front wheel is refitted. Shops that don't know airheads may not do this. This can also result in the forks running in a different way than they were before.

    Every time the bike goes on the centerstand the forks drop to full extension. And you don't have to align the forks when the front wheel is removed.

    I'd forgotten that. Real centerstand. Haven't had one in too long.

    Align the forks (the bouncy bouncy routine) every time. From the fork brace down, no need to disturb the triples.

    Plus the bouncy bouncy routine is applicable to many, many different bikes. Nothing airhead specific about that. Personally, I just pull the slider back out with my hands and then let the slider slide back to it's neutral position on the axle. I think it works better than the bouncy bouncy routine.

    I agree with your method, I do the same. If using the bouncy method on disk brake bikes dont use the front brake while doing so. It clamps the forks to the wheel via the brake.
