Got 12.2 then ignition on got 12.0. Bike running 12.02
No No ... that is not good enough 12 .02 running
A fresh battery has 12.7 V out of the box precharged ( bought one yesterday not knowing what battery ..here )
Try to rev it se if you can get 14 V ish and switch on the light see if it changes intensity revving
Charging outside the bike can be an option.
But it looks as you are not charging on the bike
