you dont want to miss out on them crisp cold January mornings when the air is supercharged with nitrous oxide, and two years ago i started my winter strip down at the end of September and missed out on the best October we've ever had! November and December are normally pretty shitty so the fairings will come off then, then il wipe down the engine etc with brake cleaner, degreaser etc. and spray with ACF50
Draining the tank can cause petrol pump problems but so to can old petrol and water in the tank, so it could be worth taking the tank off, draining it completely and then filling it up again. In cold areas in the States they drain the water cooling system but they do get -20. Bike up on paddock stands isnt a bad idea to save tyres. The hardest part is getting the bike upstairs and into the bedroom
other than that i just start it up every week and let it get hot enough for the fan to cut in if its too crap to go out. What i have found usefull is to attach a flying lead from each battery terminal to a connector block under the seat cowl lid. To this it is easier to connect all your alarm, power commander, speedohealer etc. leads and also your battery charger if needed.
