So thanks to your guys' help, I got my front fork seals changed out and back together handily....I also had my local shop change out the front tire for a Michelin Pilot-Activ (The old tires still have some tread but are of dubious and unknown age).
WOW! I'd forgotten what it was like to *not* wallow in a hard stop--and the bike really soaks up the bumps so much better now. Turn-in also feels soooo much better!
HOWEVER - Now I'm experiencing a mild up-down oscillation that seems related to tire rotation speed. It changes with speed, doesn't cut out when I pull in the clutch, feels more pronounced over 40 mph, and doesn't change in sweeping turns in either direction. It feels OK around town (doesn't influence handling) but the increase in oscillation over 40 is enough to give me serious pause about taking the bike on the freeway.
Could I have forgotten something putting the front end back together? Or could it be a balance issue from the shop?
