Late model Harley-Davidson® are equipped with sealed maintenance-free batteries. These do not require adding distilled water. However, they do require periodic charging. The simplest way to do so is by using a battery tender. If you don't already have one, they can be purchased at GAH-DK®. This handy little charger allows you to maintain a proper charge year 'round and comes with a lead to attach to your battery. Simply plug it into any wall outlet, snap the two together and the charger will take care of the rest! The system is designed to protect from overcharging; simply unplug the leads whenever you want to ride and plug them back together when you return! Use the system all year long!
Fill your fuel tank and add Genuine Fuel Additive (available at GAH-DK®). Run the engine long enough for the treated fuel to reach the carburetor or fuel injection system. For carb equipped models, turn off the fuel petcock and run the bike until it quits running. Leave the petcock off until you need to start the bike again. Over several months, fuel can grow stale, even to the point of becoming gummy which clogs the fuel system. Fuel stabilizer helps protect against this.
It's a good idea to change the engine oil and filter before storing your bike. The byproducts of internal combustion produce water and acids, which may be damaging to the engine's internals. Now is a good time to change the primary fluids as well. Be sure to use the correct fluids and follow the instructions in the service manual.
Check your tire pressure and correct if needed. You should be doing this between rides anyway, but now is a good time to check as well. Be sure to check it again before riding in the Spring. Need a Tire Pressure Gauge? We have them for you here at GAH-DK®.
Wash and wax. This will protect your bike's finish from moisture and corrosion. See our complete line of cleaning supplies in-store.
A storage cover is always a good idea. Make sure you do not use a rain cover as they do not allow moisture from condensation to pass through. Harley-Davidson® offers good sturdy covers that range in price and are just the ticket!
