Hey guys I have a 1978 cb750k cafe racer I'm building and I'm only running the bare minimum on it. Just the essentials like rear running and brake light, headlight, and no turn signals. Also, I'm thinking of going with Kickstart only. I would like to buy a battery that is better, smaller, and lighter then my stock one but there are too many to choose from. I know Antigravity are for electronic ignitions so can't use that. How about lithium ion? and if so what size? Thanks.
