Hi all,

I have the stock Rock Shox Pilot on my Fisher Tassajara, and I'm getting a high-pitched hissing noise from my front left suspension (the right one seems to be ok). I think it may be due to the brake dust that covers the suspension, but strangely it doesn't affect the right one. I usually put a drop or two of chain lube on it and clean the exposed parts of the suspension, and it goes away from a couple days, then returns again. How do I get rid of the high-pitched hissing for good, or at least for longer than 2 or 3 days?
