Add Fuel Stabilizer And Drain Carbs
Fill the tank with fresh fuel, but do not overfill. The correct level is when the fuel just touches the bottom of the filler neck. This gives enough room for the fuel to expand without overflowing the tank when temperature rises.
Shut off the fuel petcock and drain the
carburetors and the fuel lines. Add winterizing fuel conditioner to prevent the fuel from going stale, and help prevent moisture accumulation. Stale fuel occurs when aromatics (the lighter additives) evaporate leaving a thicker, sour smelling liquid. If left long enough, it will turn into a gum, plugging the jets and passages inside your carbs!
Lube the cylinder(s)
Tip: You only need to do this if your motorcycle will be stored a very long time (6 months or more)
Because gasoline is an excellent solvent and the oil scraper ring has done its job, most of the oil from the cylinder walls have been removed since the last time the engine was run. If the cylinder wall is left unprotected for a long period of time, it will rust and cause premature piston and ring wear.
Remove the
spark plugs and pour a tablespoon (5 cc) of clean engine oil or spray fogging oil into each cylinder. Be sure to switch off the fuel before you crank the engine or else you may refill the drained carbs! Also, ground the ignition leads to prevent sparks igniting any fuel residue. Turn the engine over several revolutions to spread the oil around and then reinstall the plugs. Refitting the plugs before cranking the engine could result in a hydraulic lock if too much oil was used in the cylinder.
Battery Storage
The battery must be removed from the motorcycle when it is in storage. Motorcycles often have a small current drain even when the ignition is switched off (dark current), and a discharged battery will sulfate and no longer be able to sustain a charge.
A conventional battery should be checked for electrolyte level. Add distilled water to any of the cells that are low and then charge the battery.
Battery charging should be performed at least every two weeks using a charger that has an output of 10% of the battery ampere hour rating. For example if the battery has an AH rating of 12 (e.g. 12N12A-4A-1 where the 12A is 12 amp hours), then the charge rate of that battery should not exceed 1.2 amps. A higher charge will cause the battery to overheat. Charge the battery away from open flame or sparks as the gas (hydrogen) given off a battery can be explosive. Elevate the battery and keep it from freezing. Exercise the proper caution appropriate to caustic substances.
Exhaust and Mufflers
Exhausts/Mufflers are known to rust fast when they are not used. So making sure they are properly stored for the winter on your bike will save them from an early rusty death. Spray a light oil (such as WD40) into the muffler ends and drain holes. Lightly stick a plastic bag (shopping bag is fine) into the end of each muffler hole (to keep moisture from getting inside the exhaust). Then cover each muffler with another plastic bag to keep outside moisture off.
Cover it.
Now you can cover the bike with the cycle cover and look forward to the first warm day of spring.
Back On The Road
Before you head out onto the highway, there are a couple of things to do. First, remove the cover and put it where you can find it again. Talking of finding things, locate the (charged) battery and reinstall it connecting the positive (+) cable (red) before the (-) negative and covering the terminals with the plastic covers. Recheck all fluid levels and turn on the fuel. Check for anything wrong on the motorcycle (cracked tires, broken parts/plastic, leaking oil). Set the tire pressures back to riding specs and you are ready to fire up.
As you don your riding gear, remember that your riding skills will be a little rusty and the road surfaces will have changed a bit since the last ride, so go carefully. Sand/salt deposits on the edge of the road and especially at corners may be hazardous.
