Fork seal problem 81 GS1100

[Jimmin]

The fork seals on my 81 GS1100 leak after just a couple of years and < 1000 miles. God knows how many times I have changed them in 27 years.

I have used OEM parts with below average life.

Wondering if anyone else has had these problems. Are there any tricks etc or can someone suggest an aftermarket brand which may fare better.

Thx Jim

change the fork bushings as well

LEAK PROOF PRO MOLY seals. I get them from DENNIS KIRK, but lots of places sell 'em.

I have never failed to have excellent performance from OEM seals. As mentioned, change your bushings as well and check the tubes very carefully for nicks or dents that may be cutting your seals up.

Something is amiss, on most of my bikes the original seals still work, have only had to change a few over the years....

Nicks on the upper tubes, or rust pits?
Wrong part?
Sand or battery acid in the oil?
Can't imagine what would cause this, unless you are damaging them when you put them in?
