The day after, I am having trouble starting, so I connect a battery booster and the bike starts immediately with no issues…
Maybe the bike has a parasitic draw that is pulling the battery voltage down during storage? Was any aftermarket electrical added?
You might want to do a test:
1) System (at battery) voltage resting, before starting and at least 3 hours after charging
2) System voltage while cranking to start
3) System voltage while running at around 2500 rpms or more
These three numbers will tell you a lot about your battery and charging system.
All of my machines have an SAE connector attached for charging and connecting accessories.
