Motorcycle Questions? Ask a Mechanic.
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, make and model of the motorcycle please?
Still, it would appear to be a battery issue. Proposed preliminary tries (if have not been done) would be to re-inspect the battery, its ground lines and/or re-check and re-clean the battery cables + terminals, connectors and wiring as a preliminary consideration.
Then have the battery externally charged and also LOAD TESTed (even if new/charged and just for the purpose of eliminating it as a suspect).
