Sounds good! Best of luck on your soon to be launch!
If your DRZ's are like my DR650, then the bike will bump start and run even with a dead battery. (be good to know this one way or the other) But I get your point, bumping starting in soft dirt or sand is a PITA. Also, can't recall on DRZ, but the DR650 headlight does NOT cut out when ignition switch is pushed like on some bikes. I know in UK many bikes have headlight ON/OFF switch. I would get in the habit of always shutting off headlight before cranking. Over long run will help battery life. I put a switch on my bike for just this reason.
Cheers!
