How close is the checking right now?

List, The symptons include spongy keys, lack of repetition, and overall lack = of=20 control when playing fast runs. It's also difficult to feel = aftertouch,=20 even though it's there. A 1999 Yamaha U1, purchased brand new in the U.S., after customer = complains=20 I proceed to the following: 1. With all cabinetry in place, the keys stay up on the balance pins = when=20 lifted upwards. I eased the balance rail holes a bit. The keys no = longer=20 stay up. 2. I slightly weakened the damper springs. The symptons are as evident as ever. Do I try lubing the capstans,=20 balance/front rail pins and key bushings with protek? Regulation looks good, very good & uniform. There is only slight = excess=20 lost motion. The symptons get better with left pedal depressed. Any suggestions?
