Best i can do to shorten the story...

I just bought a bike today, honda nsr sp. Rode on with a spoilt fuel gauge (unknowingly) so actually had the bike died on me enroute home.

At this point i kick start multiple times before realising that tank was empty.

Aft filling the tank full, i am unable to start the engine via kick starting at all. I can only start via push start.

I am assuming the battery is gone (pls do correct me if im wrong). Wanted to ask what kind of dmg could i possibly had caused to the bike esp by trying to start the engine multiple times on empty tank.
