I don't have a lot of time in the 206, but at one time (not anymore) I would double check that the throttle was closed (by opening it) before starting with the battery on. I rarely started it with boost pumps on. I never had a problem, but I have heard it could light off when you hit the starter. I (knock on wood) have never hot started, but been around plenty. The only time I saw damage was when it was started with the throttle open. You can save it if you're quick, but mess up and you'll have some big bills coming! You will notice a weak battery right away as it winds up slowly and the igniters don't make their rapid clicking sound. If in doubt, get a cart. Be careful with pedal inputs at high power settings. It's easy to overtorque if you're not careful.
