never....unless you actually get it out and ride for a half hour or so.

 

WD 40 or ArmorAll on rubber (especially tires) = BAD

Never put a slick tire dressing on your tires...you're looking for trouble.

And what everyone else said about idling...leave her be till spring

 

Most tire manufacturers recommend that the only substance used to keep rubber shiny should be good old soap and water.

 

Start it if your gonna ride it,if not don't !!!

 

I concur with everyone else has said, leave it alone until spring when the weather breaks. Don't forget the battery tender.

 

I agree. Let it rest with a battery tender and some gasoline preservative mixed in with the full tank. Spring will come soon enough.

 

If you're not going to ride for a while couldn't you just un-hook the battery instead of a tender?

 

You want to keep the battery charged.

 

I definitely concur, Just idling it won't get it up to operating temps uniformly and might actually do more harm than good. Properly "pickling" the motor with fresh oil and stabilizing the gas is the way to go.

 

I don't know if this applies, but aircraft engines are also air-cooled.

People start airplane engines and ground run them thinking this is good for them during storage. It is not, in fact it is the worst thing they can do.

Ground running never brings the engine to actual operating temperature. It just makes them warm, which atracts moisture then rust. This shortens the life of a $30,000 engine by about half.

When you fly the plane it gets to actual operating temp and boils any water/moisture out. So changing the oil and letting it sit is the best. Most pilots know this, but I see people ground running almost any weekend.
