If you have an alarm fitted then it could be that draining the battery. As Darrsi said, the headlight mod is not the cause
Once started, the voltage across the battery should be around 13.5 - 14Vdc assuming your alternator is good. Sitting with the engine off after running the bike for about 15 mins then a resting battery should measure around 12.5Vdc.
No 13.5 - 14Vdc = possible poor alternator/battery connections or knackered alternator.
No 12.5Vdc after a 15 min engine run = knackered battery
Good luck fella :thumbup

Those are my principles...if you don't like them I have others.
