Forza charging problem

[Isaac]

Hey, I have a 14 Forza 300 when running the battery charges but not enough. When fully charged and running the meter read 13+ volts and goes up when pulling the throttle and after driving for 30 minutes it drops to 12.7 volts when idle and up just 00.01 volts every 2 seconds with the throttle pulled. What might be the problem with the charging system?

Why do you think there is a problem, does the bike have starting issue or any other issue...?

The voltages you mention are about normal and expected I think...
