  • Another fork question ...

    I was checking the fork air in my SF today and noticed that both forks still had air pressure, 7 and 13 psi. Prior to that, I thought both of the forks had leaked out all the oil and air and that's how they'd gotten so squishy but the external signs of leakage aren't present .... BUT, I was wondering .... If a fork holds air pressure, doesn't that mean it should hold oil without leaking too?

    I guess it would be possible to leak oil out of the damping rod bolt at the bottom of the fork or the oil drain screw and only lower the air pressure slightly. The seals, for sure would leak air first before oil. Same with the air valve on top. For good handling, it's important to have the levels of oil in each fork the same. Same goes for the air pressure. I've done away with the air systems and gone the Progressive spring route, with no air pressure needed. World of difference in the handling. HTH

      Thanks again, Bikerphil ...

      That's kinda' what I thought ... guess I'll change out the oil and equalize the pressure and see how it handles then ...it's anybodys guess what's in the tubes now. I kinda' ride like an old guy anyway and this bike currently has a fairing on it, but only temporarily, further weighing down the front end ... I'm changing it back to stock naked SF ... so I'll probably just leave the factory setup alone so long as it works correctly. Really appreciate the input.

        For the $65 to $75 online price, new fork springs are GREAT. As Biker said, you will no longer keep air in the forks, and the handling WILL be nicer!

          Thank you too , Diver ...

          I looked over the Progressive site and I guess I hadn't realized that you used their spring without the air. Just now learned this from Bikerphil and yourself.

          I think I'll leave the Progressive option to the NO(next owner) though, at least on this bike for the time being ... think I'm gonna' try to get down to only one XS .... yeah, right This nice little Special is lookin' for a new home
