Just brought our "new" 2004 Silver Bullet II home from Orlando and immediately did the Sticky Key repair.
Doing so, I had to disconnect the battery during the repair to prevent other fun and games.
Fired up Bullet and the sticky was gone but the BAS/ESP light was on.
That said, as described in the 2004 owners manual page 76:
Synchronizing ESP
If the power supply was interrupted (battery disconnected or discharged), the BAS/ESP malfunction indicator light may be illuminated with the engine running. To re-synchronize the ESP, and cancel the malfunction indicator light, the steering angle sensor will need to be recalibrated.
1. Turn the ignition switch to the ON/RUN position.
2. Rotate the steering wheel to the center position.
3. Rotate the steering wheel completely to the left, and then rotate the steering wheel completely to the right.
4. Bring the steering wheel back to the center position.
5. The BAS/ESP malfunction indicator light will go out.
If the BAS/ESP malfunction indicator light is still illuminated, the vehicle should be serviced at an authorized dealer.
I did the above 5 steps and the BAS/ESP light went out and has stayed out.
Cheers,
