1974 250 CR kickstarter question

I just picked up a 1974 Mag 250. This is my first vintage husky, so I am a complete noob. My question is that when I kickstart the bike, the kickstarter goes all the way around and makes contact with the left side cases. I'm scared to death that I will crack them. Is this normal or is something adjusted wrong? Other than that, the kickstarter feels normal. The owners manual does warn not to preload the kickstarter on the splines as it make crack the stop if the bike kicks back. Any insight would be greatly appreciated.
