I have a 2003 VN750 and have just installed a MF battery. It starts pretty well when cold. I just set the choke and it usually fires right up. It doesn't always do that when warm though. Should I give it a little throttle durning warm starting? I have read that a MF battery improves starting and it did seem to help, but it isn't perfect. I will be putting in NGK Iridium plugs later, does that help?
