A minor correction. While the 400 uses roller bearings, a 650 like the OP has used plain bearings on the crank and conrods.DL-11 said:The Burgman engines use a roller bearing crankshaft and connecting rod. The bearings and bearing surfaces can rust while not in use if they're not protected by a film of oil.

im in alabama. we ride all year round. it only snows a few times a year here. and even then it doesnt stick.
gosh, just the thought of putting the bike away for a few months make me very sad.
From my experience, unless you can get the engine's oil over 200º F AND keep it there long enough for accumulated moisture to be boiled off, you'd probably be better off just letting the bikes sit silent until you're ready to ride them and then taking them out for a long hard ride, under load, to get everything hot enough that it will do some good. The fact that the cooling system gets warm doesn't mean the oil gets HOT, and that's really more important than water temp. Oil doesn't get very warm in an engine that's sitting and idling under no load. Repeatedly heating and cooling the crank case without getting, and keeping, the oil thoroughly HOT will actually cause more condensation to accumulate inside the engine than would have if the engine weren't run at all during the cold weather."Then on bikes I'm not taking out on roads with salt and etc I run them for 35 or 40 minutes to get good and hot every three weeks."
