So basically I bought a used gsxr 750 about a month ago. Rode home and everything was good but the next morning the battery seemed to die. To this day even after i replaced the battery with a brand new one. It works fine if i jumpstart it with a car using cables but doesn't jump with my 750amp jump starter. The previous owner said that the owner before him installed some lighting kit and did the wiring himself so I was wondering if something related to that is causing the issue. I tried starting it today and idk how but it started just fine after not being started for about 5 days. I love the bike how it handles and everything and really tryna ride it this summer. Please help.
