If I were storing the bike in a heated garage I'd just start it every so often and wouldn't even bother draining the bowls. Since my bike will be spending the winter in an unheated shed, subject to below-freezing temps for 3 months, I drained the bowls after filling the gas tank with fuel and Sta-Bil. The lack of an "off" on the petcock is a real PITA and I'll be adding a fuel shut-off to the fuel line this spring also. Luckily draining the bowls is no big deal. I know the Ninja is an entry-level bike and all, but did they have to omit the "off" position on the petcock just to save a few bucks and keep the price down?
