Love the people who tell you to ride the bike in the winter, i stretched it out to December last year, up here in Canada.
The last ride was when i saw snow coming down. Makes falling asleep loads easier when you just went through 40km in negative degree temperature in a pair of jeans :P
In any case, like the first reply said, with a bit more details as to why:
- Change to fresh oil (which will be good to go for next season), you don't want to leave it to dry out inside of there without oil.
- Put battery on trickle charger, don't have to be continuous, 2 times each winter for half a day is fine. I would take it off the bike all together, This will prevent parasitic discharge from draining your battery to failure.
- Lift the bike off the ground, save your tires from getting "flat spots" or you will have a bumpy ride next season.
- Fill the tank, this will prevent your gas tank from rusting.
- Empty carb bowls, will prevent the jets from getting clogged.
- Turn petcock off (not on prime), this won't allow gas to flow to the carb unless you create a vacuum (ie turn the bike on).
Hope this helps, but i think you have plenty of time before you have to store your bike away
