07 750 cranks really slow. I always have the trickle charger on the bike, I only ride it a few times a week. When I hit the starter the bike cranks really slow..more often than not it will not start. After a few tries it will eventually fire up. Once running it idles and drives fine. I replaced the battery, stator and rectifier a few months back. The battery is at 12.5v when the bike is off and climbs to 14ish when running so I dont suspect a charging issue. If I shut it off and try to restart I am getting the same slow crank issue. It happens when cold and hot. Thinking starter or starter ground? Any ideas? Thanks in advance!!
