What are you doing?
My Bandit is sitting inside my trailer, so I'lll just top off the bike with stabilized gas after the last ride this year.
I figured I'd start off this thread to encourage you to think about what you need to do to prep your bike for the 'idle months'.
Taking a few minutes now prevents damage, and makes spring start up so much less painful!
Usually, all I do is treat the gas in the bike with Stabil, since the bike may be rolled out on nice-ish days.
You'll want to fill the tank up with fresh, stabilized gas as far as you can, and run the bike a few minutes to let the stabilized stuff circulate throught he fuel system, or be prepared to drain the fuel system.
Depending on where you store the bike, you may want to wash and wax the bike, and at least cover it up.
If the bike is going to be parked somewhere there are 'critters', you may want to cover up any inlets mice, rats, and bugs can get into.
If it's damp, either polish all chrome, or wipe down all metal surfaces with an oily rag. No sense finding rust in the spring...
You can pull your battery out for the winter, or leave it in the bike.
Either way, you may want to use a maintenance type trickle charger, or charge the battery periodically, maybe monthly.
Cranking the bike up for a few minutes at a time over the winter probably won't do much good, but, if it makes you feel better.......
Winter is a good time to do those little upgrade projects you've been putting off, also.
Some people will totally fill the engine with inexpensive oil. I'm not sure it's worth the effort, but it's your call.
There's a lot of other stuff. It's nice to start the season off with fresh fluids. How's your brake fluid? If it's not clear, and has a brownish color, it's time to change it.
