If you don't use the halogen headlight, you could get away with a much smaller battery than the stock 12N12A (which is a 12 amp battery). I'm running a 4 amp lithium ion battery in my 450 with all LED lights and no electric start.I just purchased a 75 Honda CB360. It already has the starter removed. What size battery (Ah) is recommended for just a kick start, and mix of Halogen (front) and LED (rear)? Thanks!
