when I take my seat off it seems like I am pulling it slightly forward with my left hand & right hand on the key.
first thing to do on a Y2K is get rid of the original rubber brake lines if they are still on the bike. there are quite a few failures on the lines. they can look good on the outside but be coming apart inside. mine did about 2 years ago (apx 27000 miles on a well kept bike). I got front brakes that would not let off and rear brakes that didn't work at all. also got hunks of rubber in the ABS module & killed it. other than that... love the bike.
