    What's the purpose of having two fork seals in the lower fork legs?
    Was this design a flaw and needed two seals to keep from leaking?

    They had two seals, even 3 some years, in an attempt to keep them from leaking. Didn't work!

    Try the 40mm seal from K&S #16-1036. Not a perfect cure, but much better. Just use one in each leg.

    and using both the stock wiper and those ugly after market fork boots will help keep the mung out. my fix was putting a 2001 honda cr 250 front end on.

    How difficult was that front end swap.
    I've been thinking of such a transformation but don't know what matches up with minimal machining.

    I had a buddy of mine machine the bearing races down with a cylinderical grinder ( he works for IBM) .030 and used two spanner nuts (the one that resides under the top triple clamp) one I filed all the threads out of for a spacer. and the rest pretty much bolted right up. aside from having to do new neck bearings (honda)fork seals, wheel bearings and some stripped hardware it was fairly cheap. just over 100 bucks with machining included.
