Starter Or R/R
I recently purchased a 1987 Vulcan 750, owner said the battery was dead. It would run for 1 week and the battery would go dead. So I figured I'd purchase a new battery. The bike still has the same issue, it runs for about a week and then the battery goes dead. After doing someone research, I purchased a voltage regulator. I checked the voltage at battery terminal and it read 12.35. I brought the RPM's up to 4k and it read 13.75. Any feedback or suggestions? Is 13.75 sufficient?
