Fork seals, what to expect from them.

(1/1)

Athame57:
The fork seals I have on my current bike, a CB400F2 I've had for about 15,000 miles and seven years the longest I've owned any one bike. I haven't a clue what these seals have done before my watch began. I've seen 52,000 on one new bike in a year as a dispatch rider but that's a different test.
Should I let a sleeping dog lie or is it high time I changed them ahead of failure? :-\

Nurse Julie:
If theres no sign of weepage, leakage or seepage, leave them alone George. It's the usually rust or pitting on the forks that causes a leak around the seal.

Dried bugs-plash is also notorious...
And worn out fork-bushings or fork bottoms, allowing lateral play...

Spitfire:
I'm with Julie, if its not broke don't fix it.
