    I am in the midst of replacing a drive shaft and final drive on a
    Kawasaki Vulcan 750. This is caused by the drive shaft splines being
    stripped as well as the ones on the final drive.
    What should I do to make sure this doesn't happen again. I see no way
    for that area to be lubricated. I'd rather not have to do this again
    in another 15,000 miles or is it just something I need to plan for in
    the future.
    Any help is appreciated.

  2. Very popular with BMW riders too. I do an annual spline lube
    with the Honda Moly paste myself.

    Thanks for the information and the idea of making it an annual
    maintainance. Those of you that have used the Honda Moly, how did you
    apply it and about how much should be used?

    You should use molykote FB180 grease for the spline.
    Not the usual molybdeen dislufide grease, it will be trown off the
    spilne due to rotation forces, FB180 sticks to it much better.
    BMW uses staburags.... grease which has the same qualifications.
    On the connection form the final gear to the wheel we call is meenemer
    in dutch you can use any ordinary molybdeen disulfide grease.
    The wheel will get off every 10 to 20 MM (Mega Meters.) So it get
    greased reguraly.

  5. I use a brush. Solder brush, old toothbrush, something like that
    and aply enough to coat both surfaces without extra gobs sitting
    anywhere. About the only place I have to really worry about
    excess is in the front where it could potentially crap up
    the clutch. Other than that, a little excess makes no difference
    at all.

    I found that the Honda Moly seemed to go south in about one year. The
    result was stubborn downshifts in the lower gears. Seemed to dry out quick
    for some reason, maybe excess rains I've ridden in and condensation added to
    the problem.

    I'd hate to make it a practice to do a BMW clutch spline lube every year.
    Least you can get an eye look on the seals to see how many are leaking at
    the time it's done. ;o\

    Someone said something about some waterproof spline lube by the boating
    company (Evenrude?) that may work better. I've had good luck with Yamaha's
    lubes, tire mounting spray, and Yamabond gasket cement, but don't know if
    they have a specific spline lube product.

  7. I rack up about 10-15,000 miles a year, and usually lube the
    splines and aftermarket U joints (R100 GS) at the same time.

    Both could probably go longer, but over the course of a year
    they'll go through a few creeks and this seems like a nice safe
    service interval.
