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, proposed preliminary tries (if have not been done) is to check the starter relay. To locate the starter relay, start by following the big cable from the + terminal of the battery as it always ends up tied to 1 of the 2 big terminals of the starter relay. Carefully but quickly/momentarily jump the two (2) big terminals. This is a bypass of the starter relay to enable the starter motor to spin:
Still and on the "...tested the battery...", please consider a re-test; i.e. measure the battery voltage with a volt/multi-meter when:
to test for presence and consistency.
Of course, the prescribed preliminary approach would be; inspect the battery & ground lines and/or check/clean the battery cables + terminals as a preliminary consideration. Better yet, have the battery externally charged and then load tested (even if new and just for purposes of eliminating it as a suspect).
