Maybe I'm just odd BUT I pull the plugs and mist a bit of diesel fuel into the cylinders, not much just a few squirts with a old glass cleaner bottle. A old friend that had been riding for longer then I've been alive told me this helps to keep rust from forming on the cylinder walls and piston rings.
I do this AFTER I change the oil and filter then add stabil to the tank and drive for a few kilometers to ensure the stabil is all through the carbs and the fresh oil has 'flushed' the old oil that just never drains. Refill tank leaving just enough room for expansion on them warm days. Put the bile on center stand, jack the front end up so BOTH tires are off the ground. Drop the pressure in both tires (don't know why but was told by a old biker friend that it "helps the tires"). Pull the battery, cover the bike and hope Mother Nature is kind with a early spring.
Be warned, when you first fire the bike in the spring the diesel WILL make a lot of smoke for a few minutes and takes a few more cranks to startup the first time.
Second warning, use regular diesel not Pink (farm grade) or you'll make your neighbours very unhappy with the sulfur smell that takes ages to clear. Yeah, I made that mistake just ONCE.
