i removed my center stand when i went with a right-side 4-1 exhaust. kinda had to, since the center stand stop was connected to the left side exhaust. works fine that way, and when it's going to be parked for a while i just burn off the fuel in the carbs.
in the winter i am going to drain/rinse my tank and store it inside. last winter i put a bunch of silica packets in it, sealed it in a big plastic bag, and kept it in the basement to avoid temp fluctuations causing condensation.
