I made the leap from airheads into oilheads and purchased a 1997 R1100RS on Saturday. Thanks to all here who provided some tips on what to look for.
One thing I didn't notice until I got it home was an issue with the ABS. When I turn the button on and activate the ignition, neither of the two ABS lights on the dash start blinking like I think they're supposed to do until you activate the brakes. The only thing that I do hear is a steady clicking noise, about once per second, on the lower center portion of the right side of the bike.
I haven't pulled anything apart yet. Do these symptoms ring a bell for anyone? Is there a good place for me to start?
