I'm keeping someone else's bike over the winter, but will have to put it in my unheated trailer as my heated garage is full...temps here will go down to -30 or more and winter will be long. Other than removing the battery, are there any other tips for storage in extreme cold?

 

Fill the tank and ad a fuel stabilizer then run the bike for a few min to get the fuel through the lines. Put some steel wool in the exhaust tips to keep any critters out. Now shut the door and forget about it until riding season. BTW many like to change the fluids before winter storage. That's about all you really need to do. I have stored bikes for many winters in my unheated garage here in WI with very low temps and have never had a problem come spring time.

 

Yep, what Misbehaven said. Plus, I also put some oil down the sparkplug holes, turn it over a few times (disconnect the plug wires), as it helps to coat the cylinder walls with oil to prevent condensation from forming. Also some damp-gone in the trailer might not be a bad idea.

 

Don't kiss any metal parts

 

Right on.
I do like to change the oil before, so the moisture in the old oil isn't in the engine.
Cover it with a bed sheet and pray for an early spring...

BTW, Misbehaven, I live in Plymouth. Good to see another local on here!

these 'cold' threads are depressing, manopause(Post Motorcycle Season) is setting in...ugh.

 

Only thing I do additionally is connect a battery tender and place a breathable cover over it. If the floor in the storage area sweats from condensation, you might also roll the bike onto a piece of carpet, plywood or cardboard.

 

+1 and I would add a Battery Tender

 

Things I've learned on this site.
- Tires will get flat spots so you have to jack it up. But leaving the jack on the frame that long will bend the frame at the point where the jack sits.
- If you don't drain out the old oil, the acid buildup in the oil will dissolve the cast metal inside your engine and by spring your engine will be totaled.
- If you cover the bike condensation will form under the cover and rust out all the chrome parts.
- If you don't cover the bike it will get a layer of sediment from the dust in the air that will ruin the finish on the bike beyond repair.


So the way I figure it, a bike can't make it through the winter. We're all screwed.

 

This is how they store a bike in Sweden.
