I remove my seat and store it in a plastic bin to keep critters from possibly chewing on it. (This happened to one of my 4 wheelers) I also put fabric softener sheets in the exhaust, air intake and saddle bags to keep critters out.Shutting off the fuel and letting the engine starve to a halt is a good idea, but I haven't had a bike in the last 20 or more years that actually had a fuel switch. With EFI I add the stabilizer (Stabil) and let the engine run for 5 to 8 minutes and then turn the key to off. I've never had a problem come Spring. I use Battery Tenders rather than a trickle charged. Once hooked up, I never need to touch the Tenders until Spring. I do stuff rags into the exhaust pipes to discourage the potential critters that might want to make in a nest in them.
