I've got a Honda Motorcycle question?

I picked up a really cool 1979 Honda CM400t recently but found that it aint got spark, it has a kickstart and I got ahold of a manual for it and was reading that it doesn't have a magneto. Would my motorcycle with a CDI need battery for spark? EVEN with a kickstart? I had just always thought you didn't need a battery for kickstart, but it has electric start too. Any answer appreciated!
Added (1). I will be picking up a battery on Friday by the way!
