Winter is fast approaching and if you live in a frigid climate it’s time to store your bike for the season. In storing your bike for a few months over the winter, your main concern is to avoid corrosion while in storage and the goal is to have a bike that is ready to go when you are.
The most crucial areas in need of protection are the piston rings, cylinder walls, and valve seats. The enemy here is moisture, which can enter the engine from any of a number of places and cause serious damage. Since its not really practical to try and close up all of the possible areas of entry, we will concentrate on moisture proofing instead.
The first step is to warm-up the engine. This drives off any moisture that may have accumulated already and it makes it easier to get a good coating of oil in each cylinder. Turn the bike off and remove the spark plugs. Then, using a turkey baster, suck up 25cc’s of engine oil and squirt the oil into each plug hole. Turn the engine over by hand (put it in top gear and turn the rear wheel) with the plugs still out to coat the cylinder walls, piston rings and valve seats. Then replace the plugs and drain the existing crankcase oil.
