How old is the battery? A bike battery, in good condition, should be charged up once a month if not being used and kept charged up. If the bike hasnt been used for a period of time and the battery has gone flat it will soon become less efficient and gradually deteriorate. The best way of storing a battery, in MY opinion, is to disconnect it from the bike and have it on an "Optimate" charger/Optimizer. This special charger monitors the battery and detects when it starts to discharge, then "kicks in" to bring it back up to its optimum state. The other thing to check is good connections to wiring, especially earth (ground wire) for solenoid and starter motor, battery earth (ground) good clean solid tight connections with no corrosion. Also, starter motor brushes! `03 is quite old now so check the brushes are not worn out. These are just a few things I can think of checking off "the top of my head"! Hope it helps.
