How to Test a Harley Crank Position Sensor

A Harley-Davidson motorcycle engine may sputter and hesitate when a crank position sensor (CKP) starts to fail. The CKP sends data to the motorcycle computer data center about the position and speed of the crankshaft, the ignition and fuel injection. A malfunctioning CKP can cause the engine to backfire due to unburned fuel and hesitate when accelerating. The symptoms of a faulty CKP worsen when the bike is revved up. Contaminated fuel or bad spark plugs can also cause similar problems, so you may need to test the crank position sensor.

Difficulty:

Easy

Instructions

Things You'll Need

• Pencil
• Paper

1. • 1

     Turn the key in the ignition to the "Off" position. Turn the "Run/Stop" switch to "Run." Push and hold the odometer "Reset" button. Hold the "Reset" button and do not release it yet.

   • 2

     Turn the key to "Ignition," but don't start the engine. Release the odometer "Reset" button. Wait for the odometer to indicate the bike is in diagnostic mode by displaying "Diag." Push the odometer reset button and then release it when you see the "P" in the menu selection flashing.

   • 3

     Wait for the bike to complete the diagnostic of the electronic control module and the ignition control module. Write down the codes that are displayed after the diagnostic is complete. Code PO 374 indicates a failed or faulty crank position sensor due to a synchronization error.

Tips & Warnings

• The following codes are reported for the crank position sensor:

• P0373 CKP Sensor Intermittent

• P0374 CKP Sensor Not Detected

• P0374 CKP Sensor Synch Error EFI

• You cannot service crank position sensors, and you should replace them if faulty or damaged.

How to Change a Harley-Davidson Tire

Harley-Davidson's motorcycles are famous for their ability to be ridden for long distances. During these long trips, the motorcycle's tires will wear away and require eventual replacement. While most Harley-Davidson owners delegate the task to a mechanic, changing the tire yourself is a rewarding and money-saving endeavor. If you are willing to take the time to do the job yourself, make the investment in a sturdy motorcycle lift that will support your Harley-Davidson while you remove the wheels and tires.

How to Rebuild a Carburetor for a Harley

Close up engine

If your Harley is not running the way it should, it might be time to rebuild the carburetor. S & S is a popular carburetor for a Harley V-twin engine. The fuel to run the Harley runs through the carburetor, mixing with the right amount of air, leaving sediment and particles behind gumming up the inner works of the carburetor. Once the particles are in the carburetor, the bike will not perform as it should. It will run sluggish and possibly not even start. A rebuild kit for the carburetor can be purchased at most motorcycle part supply stores. The process of rebuilding a carburetor is not too difficult.

Difficulty:

Moderately Challenging

Instructions

Things You'll Need

• Screwdriver
• Carburetor rebuild kit
• Carburetor cleaner

1. • 1

     Disconnect the fuel line and drain the carburetor. Remove the carburetor from the intake manifold. Check the plugs that are located in the body of the carburetor for signs of leaking. If signs show that they are leaking, replace the plugs.

   • 2

     Remove the idle mixture screw. Count the turns it takes to remove the screw, make a note of how many turns it took. Check the throttle plate for wear. There should be no light showing when the carburetor is closed. Replace if necessary.

   • 3

     Clean the idle mixture screw and mark it with a marker just to the tapered part. Replace the screw by screwing it completely into the carburetor. Remove the screw and check to see if any of the marker has been rubbed off. If it has, use the new idle mixture screw from the kit and discard the old one.

   • 4

     Remove the enrichment plunger nut and spring from the carburetor. Check the tip of the plunger for wear.

   • 5

     Take the screws out of the bowl of the carburetor. Do not remove the cap.

   • 6

     Remove the float pin screw. Locate and remove the float pin, float and needle. Replace if warn with new parts in the rebuild kit.

   • 7

     Take the seat from the bottom of the carburetor bowl. Install the new seat that is in the rebuild kit.

   • 8

     Check the ejector nozzle for kinks or wear. Install the new nozzle O-ring.

   • 9

     Clean and check the float for holes. Install a new needle. Place the entire unit back into the bowl. Move all the parts to be sure they move easily.

   • 10

     Turn the bowl over and take out the screws that held the cap in place. Take the balls and O-rings out of the casting.

   • 11

     Replace the ball checks, seats, spring and diaphragm with the new ones supplied in the rebuild kit.

   • 12

How to Check Oil in a Harley Davidson

Many motorcycle riding courses instruct their students to check their motorcycle's oil supply before every ride. This is a fairly simple task for most motorcycles, but Harley-Davidson machines, which use three separate oil types, pose a rather unique problem. While the motor's oil supply and the transmission fluid can be checked easily with the dip sticks built into the filler caps, the primary drive's fluid supply is only accessible by removing the primary's round derby cover.

Difficulty:

Moderate

Instructions

Things You'll Need

• Towel
• Harley-Davidson 20W50 motor oil
• Harley-Davidson primary fluid
• Torx-27 screwdriver
• Harley-Davidson transmission fluid

1. Checking the Motor Oil

   • 1

     Start the motorcycle. Let it warm up in place for three minutes, then stop the motor.

   • 2

     Unscrew the filler cap from the right side of the oil tank, below the rider's seat. Wipe the cap's dip stick clean with a towel.

   • 3

     Reinsert the dip stick completely into the oil tank and withdraw it. Take note of the oil level in relation to the Add line marked on the dip stick.

   • 4

     Pour 20W50 motor oil into the oil tank's filler neck to raise the oil level as needed. Reinsert the dip stick and screw the oil filler cap into place.

   Checking the Transmission Fluid

   • 1

     Unscrew the filler cap from the right side of the transmission unit. Wipe the cap's dip stick clean with a towel.

   • 2

     Reinsert the dip stick completely into the transmission and withdraw it. Take note of the oil level in relation to the Add line marked on the dip stick.

   • 3

     Pour Harley-Davidson transmission fluid into the transmission's filler neck to raise the oil level as needed. Reinsert the dip stick and screw the filler cap into place.

   Checking the Primary Fluid

   • 1

     Unscrew the derby cover's bolts, using a Torx-27 screwdriver. Pull the derby cover and its gasket away from the primary cover to access the clutch inspection port.

   • 2

     Look into the primary cover through the clutch inspection port. Take note of the primary fluid level in relation to the bottom of the primary's clutch assembly.

   • 3

     Pour Harley-Davidson primary fluid into the clutch inspection port to raise the fluid level to the bottom of the clutch assembly as needed.

   • 4

     Reinstall the derby cover and its gasket onto the primary cover. Tighten the derby cover bolts, using a Torx-27 screwdriver.

Tips & Warnings

• You do not need to check the primary fluid level on a Harley-Davidson Sportster. Sportster models do not use a separate oil supply to lubricate the primary, relying on the motor oil instead.

How to Convert a Harley Sportster 883 to a Bobber Chopper

Bobbers became popular with soldiers after World War II.

Flag this photo

Bobbers date back to the World War II era. They came along before choppers and were simply modified stock motorcycles. Some of the modifications were removing fenders, blinkers, the windshield and anything else that was not necessary for the motorcycle to perform correctly. Smaller gas tanks, smaller headlights and springer front ends were also installed. Solo seats with springs for comfort were all the rage, as well. Choppers are basically extended versions of bobbers.

Difficulty:

Challenging

Instructions

Things You'll Need

• Mechanic's tool set
• Motorcycle lift
• Solo seat with 3-inch springs (and mounting hardware for the Sportster 883)
• Bolt-on rigid hardtail or solid struts
• 2-inch under Springer front end (This is optional depending on the look you want)
• Drag handlebars or Ape hangers (if you choose Ape hangers you will need to purchase longer brake and clutch cables)
• Handlebar risers
• Side mount for license plate and brake light.
• 1 Smaller size mirror

Suggest Edits

1. • 1

     Remove the turn signals. Follow the wires to their respective plug-ins and disconnect. Check with your state laws about turn signals on motorcycles.

   • 2

     If you plan to use a Springer front end you will need to place the motorcycle on a lift. Remove the front tire and brake assembly. Remove the headlight, handlebars and handlebar components. Remove the handlebar risers and the steering neck nut and triple-tree. The front end should slide right out of the frame, and you can then replace it with your Springer front end. Install the brake assembly and front tire.

   • 3

     Install your new risers, handlebars and smaller mirror, and assemble your components. (If you plan on using ape hangers you will have to purchase longer brake and clutch cables, as well as extend the wires for any electrical components attached to the handlebars.)

   • 4

     Remove the seat and install the new solo seat with properly fitted hardware. (If you are installing a rigid hardtail, skip this step until the hardtail is installed.)

   • 5

     Install hardtail struts in place of the stock suspension. If you are using a bolt-on hardtail instead of struts you must remove the rear tire, brake assembly, exhaust, fender, suspension, and swingarm. Bolt on the hardtail with provided hardware. Install rear tire, brake assembly and exhaust.

   • 6

     Remove the brake light and license plate mount from the rear fender while it is off the motorcycle. Modify your fender as desired or go with no fender. Install the fender without the brake light or license plate mount.

   • 7

     Install the side license plate mount with the tail light to the rear wheel axle. Use the existing wiring to connect the new brake light.

Tips & Warnings

• Some people change out the gas tank on bobbers to a smaller tank. Because the Sportster already has the smallest tank available, this step is not needed.

• Check local and state laws before any modifications are made to your turn signals and license plate placement.

How to Adjust a Harley Clutch Cable

Harley-Davidson motorcycles are built to withstand the stress of long-distance riding. A proper maintenance routine, however, is the key to your motorcycle's continued performance. As with most motorcycles, many Harley-Davidson motorcycles rely on a basic, cable-actuated system to operate the clutch. Cable upkeep is low-maintenance; however, these cables stretch over time, causing an excess of free play at the clutch lever. If left unchecked, excessive free play at the lever will prevent the clutch from disengaging completely, leading to premature transmission wear. Prevention comes in the form of routine cable adjustments, which rein in the amount of free play allowed at the lever and keep clutch engagement operating properly.

Difficulty:

Moderate

Instructions

Things You'll Need

• Torx-27 socket
• Socket wrench
• Combination wrench set, standard (SAE)
• Primary fluid
• Towels or rags
• Motorcycle stand or lift (optional)

1. • 1

     Locate the cable adjuster at the middle of the clutch cable and twist clockwise until the adjuster is seated against the cable sleeve. This will loosen the cable and place the clutch lever is at its loosest point.

   • 2

     Access the clutch adjuster in the primary cover by removing the derby cover, using a Torx-27 socket to unscrew the two mounting bolts. If the motorcycle is parked on its side stand, a small amount of primary fluid may spill out of the derby cover port.

   • 3

     Locate the clutch adjuster in the primary cover and loosen the clutch adjuster lock nut with the appropriately sized wrench, unscrewing the lock nut two complete turns out.

   • 4

     Reset the clutch cable's slack by turning the primary's clutch adjuster clockwise until it is seated against the clutch release. Do not over tighten the adjuster---it should be touching the clutch release without placing pressure on it. This will remove all slack from the clutch cable.

   • 5

     Loosen the clutch adjuster by turning the adjuster counterclockwise a full turn from the seated position to provide a small amount of free play in the cable. Tighten the clutch adjuster lock nut while holding the adjuster in position.

   • 6

     Pull and release the clutch lever to ensure that the cable is moving properly within the cable sleeve. Twist the mid-cable adjuster counterclockwise to tighten the slack in the cable, leaving 1/16 inch to 1/8 inch of slack at the clutch lever.

   • 7

     Wipe away any primary fluid that may have spilled and top off with fresh fluid before replacing the derby cover. Tighten the bolts with a Torx-27 socket.

Tips & Warnings

• For best results, adjust the clutch play when the bike is cold.

• Place the bike on a stand or lift to provide additional stability.

• Consult a service manual for comprehensive details about this process, torque specifications and other requirements.

How to Transfer the Warranty on a Harley-Davidson Motorcycle

Harley-Davidson motorcycles are one of the most popular motorcycles in the world.

When you are ready to sell your Harley-Davidson motorcycle, you will not only want to transfer the title of your motorcycle to the buyer, but you will want to transfer the warranty as well. Every new Harley-Davidson motorcycle comes with a two-year warranty that begins the day that you purchase the motorcycle. Transferring the warranty to the buyer allows you to not be hounded by the buyer, if the bike malfunctions after the transaction is complete.

Difficulty:

Moderately Easy

Instructions

1. • 1

     Locate your local dealership. If you do not know the location of your nearest dealership, visit the Harley-Davidson website and click the "Dealer Locator" button at the top of the page. Input your "ZIP Code," "City," or "State," and then click "Find." Write down the address of your nearest dealership.

   • 2

     Visit the dealership and ask a sales associate or the financial manager for a warranty transfer form. On the form, include information, such as the motorcycle's VIN number and the address, phone number and name of the buyer and seller. The seller and the buyer must sign the form in person. The sales associate or financial manager will file the paperwork.

   • 3

     Receive the warranty card in the mail. It will be sent to both parties involved in the transfer in three weeks.

How to Remove Baffles from a Harley Muffler

Removing the baffles of your muffler will result in a louder, attention-grabbing exhaust note.

Harley-Davidson motorcycles are synonymous with a deep, loud exhaust sound. "Loud pipes save lives" is a phrase heard often among Harley-Davidson enthusiasts, and they practice what they preach. The exhaust note of a customized Harley-Davidson motorcycle may be even louder than the horn that comes standard on the bike. However, most motorcycles do not come standard with a loud exhaust like the deafening ones you hear sometimes on the road. Often, this sound is the result of a modification you can make to your exhaust at home using a few basic tools and some general motorcycle knowledge.

Difficulty:

Moderate

Instructions

Things You'll Need

• Basic wrench set
• Metal-cutting drill bit
• Hand-held drill
• Vise
• Towel or rag

1. • 1

     If you have a dedicated motorcycle work-lift, set the Harley up on it so that you can reach the exhaust more easily. If you do not, simply set it on its kickstand so it won't fall over.

   • 2

     Using a set of combination or socket wrenches, remove the mounting bolts that hold the exhaust on the motorcycle. Most bikes will have two bolts on the cylinder head and two on the rear mount for each pipe. Remove the exhaust from the motorcycle. Cover any openings in the engine with a towel or rag to protect its working parts from the elements while you work on the exhaust.

   • 3

     Cover your vise with a rag or towel to protect the chrome finish of the exhaust, and clamp an exhaust pipe in it securely at the muffler to cut down on vibration while you drill through the baffles (Step 4).

   • 4

     Attach a metal-cutting drill bit to your hand-held drill. Insert the bit through the end of the muffler and drill carefully through the first and second baffles of the exhaust. Drilling through all three will result in low power from the engine and won't make much difference in terms of sound, so leave at least one baffle intact. Be sure to drill the holes as close to the center of the baffle as you can, as an off-center hole may cause "whistling" as air moves through the exhaust.

   • 5

     Remove the exhaust pipe from the vise and reattach it to your Harley using the bolts removed previously. If you have a torque wrench, refer to your owner's manual and tighten each bolt to the specifications found therein. If not, tighten each bolt about a quarter turn past "snug."

   • 6

     Start up the bike and have a listen. Rev the engine a few times to get a feel for your new deep, loud exhaust tone, then take your Hog for a ride to show off your new note on the road.

How to Change the Oil on a Harley Davidson

Like cars, Harley-Davidson motorcycles need routine oil changes to keep running at their best. Ideally, you should change your oil every 3,000 miles or so. Harley owners often pride themselves on their independence, and knowing how to change your own oil is a significant part of that. You can change it on the go without having to worry about finding a service station or paying an attendant. It rarely takes long and the process is extremely easy once you know the steps.

Difficulty:

Moderately Easy

Instructions

Things You'll Need

• Oil pan Pliers Socket wrench Siphon Oil filter Motor oil

1. • 1

     Slide an oil pan underneath the drain plug on your Harley's oil tank.

   • 2

     Hold a siphon beneath the drain plug and then -- with your free hand -- unscrew the plug using a socket wrench. The oil should drain out through the siphon and into the oil pan.

   • 3

     Replace the drain plug and tighten it into position when the oil has completely drained out of it.

   • 4

     Remove the cylinder containing the oil filter from its housing, which is usually located under the Harley's seat. You can usually remove the seat by unbolting it with a socket wrench or similar tool and then setting it aside. Be sure to keep track of the bolts and screws so that you can attach the seat again when you're done.

   • 5

     Disconnect the latch on the cylinder and pull the oil filter out with a pair of pliers. Slide a new filter into position the same way.

   • 6

     Close the cylinder and place it back into the housing, then place the Harley's seat back into position and bolt it tightly in place.

   • 7

     Uncap the oil tank and fill it with new motor oil, then seal the tank again.

Tips & Warnings

• The ideal time to change your Harley's oil is after the engine has cooled down for a few minutes, but before it goes totally cold. Any earlier, and the heat from the engine can burn you. Any later, and contaminants in the oil will have time to settle, reducing the effectiveness of the oil change. Err on the side of waiting if you're concerned about burns, but if the oil is still warm, then the oil change will be a lot more thorough. Specifics may vary slightly depending upon what model of Harley you have. Check your owner's manual to see if you should make any adjustments to the way you change your oil.

• Never attempt to change the oil while your Harley Davidson is running. It's impractical and dangerous.

How to Secure a Harley Ultra on a Trailer

How to Remove the Float in a Harley Gas Tank

Harley Davidson incorporates a fuel gauge with the instrument cluster on the tank dash of many Big-Twin and Touring models. The gauge receives input from a sending unit mounted in the top center of the fuel tank. A mechanical float/arm assembly indicates fuel level to the sending unit, which is then relayed to the fuel gauge as an electrical signal. The gauge interprets the signal and displays the status of the fuel level in the tank. The sending unit/float assembly is easily accessed and removed from the tank.

     Remove the seat from the frame. Cover the fuel tank with a thick layer of clean shop rags to prevent paint damage if a tool or part is dropped. Remove the dash hold-down bolt from the rear of the dash that was exposed by the seat's removal. Remove the dash hold-down bolt from the center of the dash and lift the dash from its resting place. Place the dash on a clean shop rag near the handlebars, clear of the sending unit.

     Unplug the sending unit wires. Remove the screws holding down the sending unit. Remove the grounding wire from the sending unit.

   • 3

     Carefully lift the sending unit/float assembly from the fuel tank hole. Cradle the float with a clean shop rag and prevent gas from dripping onto the bike at any point. Remove the assembly completely from the vehicle; do not lay the assembly on the tank. Remove the sending unit gasket from the tank.

Tips & Warnings

• During reassembly, a new gasket and mounting screws are needed. The screws have a plastic thread seal that is designed for one-time use and should never be reused under any circumstances.

• Use caution when removing the sending unit. Even an empty fuel tank will contain fuel fumes, and the tanks are steel. Using steel tools carelessly can create a spark that can effectively turn the fuel tank into a small fuel/air bomb, causing severe injury or death.

How to Change a Seat on a Harley-Davidson Motorcycle

While there are many things about a Harley that are incredible, there are some parts to these magnificent motorcycles that could have been made a little bit better. Many people opt to have serious custom work completed when purchasing a Harley for this very reason. For those planning long motorcycle trips, find out how to change the seat on these great bikes to insure a much more comfortable ride.

Difficulty:

Moderately Challenging

Instructions

Things You'll Need

• Wrenches
• Motorcycle seat
• Instruction manual

1. • 1

     Read your specific instruction manual completely in order to avoid unpleasant surprises later in the process. While there are some steps that are fairly consistent among all Harley Davidson motorcycles, there are also bits and pieces of information and requirements for changing the seat that will differ from one machine to the next.

   • 2

     Remove the existing seat from the bike. Most people find that this is a fairly simple step--as long as you use the correctly-sized wrench for the project!

   • 3

     Make sure the new saddle matches the frame of the machine. If the fit is not exact it may be necessary to either drill new holes in order to accommodate the seat or to find a seat that more closely matches the frame of the bike.

   • 4

     Begin the process of attaching the new saddle by bolting the new Harley seat into place. Most seats are designed to bolt quickly and easily into place according to make and model of the motorcycle.

   • 5

     Test the saddle in order to insure that it fits properly onto the motorcycle. The best way to do this, of course, is to take the bike out for a spin. Do not overdo the test run, as the goal is to identify and eliminate potential problems with the fit of the new seat.

Tips & Warnings

• Take the time to insure that there are no stray wires or air hoses in the way of any work that must be done in order to avoid potential damage.

• Make sure the seat is properly attached before taking a test run!

How to Repair Harley Motor Mount Vibrations

Harley motorcycles.

If a motor mount on your Harley is vibrating, the motor mount is loose or the securing bolt holding the motor mount in place is stripped. The motor mount(s) will be located toward the front of the Harley's engine, on the bottom of the engine between the frame and the engine. Some Harley motorcycle models with large engines have two motor mounts, However, most Harley models have one motor mount and one transmission mount.

Moderately Easy

Instructions

Things You'll Need

• Motorcycle jack
• Ratchet set

1. • 1

     Place the motorcycle jack beneath the engine block and raise the jack head up to the engine block to take the weight of the engine off the motor mount. If the Harley has two motor mounts, determine which mount that is vibrating.

   • 3

     Inspect the securing bolt. Look for stripping of the bolt, rust, bending or any other damage. If the bolt is damaged, replace it. Any local Harley-Davidson dealership should have the replacement bolt.

   • 4

     Replace the securing bolt to the motor mount and tighten the securing bolt using the ratchet set. Tighten the bolt so that the mount cannot move.

   • 5

     Start the engine and rev the engine a few times to ensure that the mount is tight enough that the mount is no longer vibrating.

How to Customize a Harley-Davidson V-Rod

A customized V-Rod will make your Harley stand out.

If you own a Harley-Davidson V-Rod you have most likely wondered what the bike would look like if you customized it. This is a common occurrence for anyone who purchases a Harley-Davidson. Often, owners struggle with where to start and how far they should take the customizing. Mixing traditional chroming with non-standard features will help you make your Harley-Davidson stand out in a crowd but will not take customizing to the extreme.

Difficulty:

Moderate

Instructions

Things You'll Need

• Custom seat
• Chrome hardware
• Ape hangers

1. • 1

     Replace the stock seat with a custom seat. According to V-Mod.com, a custom leather seat is a popular modification for the Harley V-Rod. A custom seat can be purchased from a Harley dealer. In addition, upholstery specialists usually offer services where your stock seat can be customized to your liking.

   • 2

     Install chrome hardware. Adding chrome to Harley-Davidson motorcycles has been popular since the 1960s. Chrome hardware like brackets, oil tanks and handlebars can be purchased new and installed on your bike or your stock parts can be taken to a facility that does custom chrome plating.

   • 3

     Install Ape Hanger handlebars. Ape Hanger handlebars rise far above the gas tank and force the rider to reach for the handlebars. This was made popular by the Movie "Easy Rider." Ape Hangers are not commonly seen on the V-Rod model so installing them will make your V-Rod stand out.

   • 4

     Replace the stock exhaust with a custom exhaust. A custom exhaust not only gives a V-Rod a different look, it also gives the V-Rod a different sound. A stock exhaust also restricts the ability for gasses to exit the combustion chamber. A custom exhaust allows gasses to escape, thus helping to create additional horsepower and torque.

About the Harley Davidson Fatboy

About the Harley Davidson Fatboy

The Harley Davidson Fat Boy is a softtail bike equipped with wide tires and fat forks. Everything about this bike says "fat," including the gas tank, which holds five gallons of fuel. The 96-cubic inch engine pounds out 90 foot-pounds of torque at 2,750 rpm, giving the Fat Boy a belly-load of power.

1. History

   • Harley Davidson motorcycles have been in existence since 1901 when William Harley drew his first set of plans. Throughout the years there have been many different Harley motorcycles. One of the best moves Harley made was to introduce the Fat Boy in 1990, giving Harley the best sales record for the heavier cruising bikes.

   Function

   • The Harley Davidson Fat Boy is a custom cruiser---made for taking long trips without too much suffering on the rider's backside. The seat is large enough for a second person to comfortably ride along on the longer trips. The Fat Boy is ideal for cross-country bike trips.

   Types

   • Different types of Fat Boys were made in different years. In 2005 Harley Davidson created a 15th anniversary Fat Boy custom cruiser with a smaller engine (88 cubic inches). This particular Fat Boy has 88 foot-pounds of torque at 3,800 rpm. While the engine is smaller than the engine in the 2007 Fat Boy, the qualities of the bike are the same---it allows for long cruises without complaints from the driver's various body parts. In 1994 the FXR frame was replaced with the Dyna frame, giving the earlier bikes a slightly different look, though in 1999 and 2000 Harley brought the FXR frame back or a few limited edition models.

   Features

   • Harley Davidson Fat Boys have many different aftermarket options that can be easily applied to the bike. One of the best options is the add-on luggage. Saddlebags are made just for the Fat Boy---the bags can be made from leather or fiberglass. The Fat Boy also has a trunk specifically made for the bike. The trunk is attached to the rear fender and sissy bar and allows for storage of extra items for long trips. There are also many bolt-on chrome applications available for the Fat Boy---from custom air cleaners to foot pegs and highway pegs. Because of the popularity of the Harley Davidson Fat Boy, there is no shortage of aftermarket pieces to prettify the bike.

   Considerations

   • 

     The Harley Davidson Fat Boy is a large bike---just one of the considerations you must take into account if you are vertically challenged. If your feet do not touch the ground, you must be an experienced rider. The weight of the bike---680 pounds dry (no fuel or extras such as bags added) will throw around even a strong person who can reach the ground in an uncontrollable situation.

How To Charge a Battery for a Harley Davidson Motorcycle

Motorcycle batteries are notorious for losing their charge. The batteries in Harley Davidsons are at times subjected to high operating temperatures under normal riding conditions. Conversely, motorcycles may remain unused for months at a time during colder months. These extremes, coupled with the smaller size of motorcycle batteries, can cause them lose their charge. Fortunately, batteries are relatively easy to charge.

Difficulty:

Moderately Easy

Instructions

Things You'll Need

• Battery charger
• Motorcycle tool kit
• Shop towels
• Safety goggles

1. • 1

     Move your motorcycle onto a level surface and ensure that it is stable. Turn off the motorcycle and ensure that the Off/Run switch is in the "Off" position. Put on your safety goggles.

Then remove the two bolts behind the rider's seat and gently pull the seat backwards to unseat it from the mount and away from the motorcycle. On newer models these bolts are designed to be removed with your fingers although, depending on the bike and options, you may need to use an open-ended box wrench or a socket wrench.

   • 3

     Disconnect the negative battery cable and wrap it with a shop towel. Repeat this procedure with the positive cable. Disconnect any straps or clamps holding the battery in place and carefully remove the battery from the battery box.

   • 4

     Consult the labeling on your battery and in your owner's manual to determine the electrical specifications of the battery. Adjust the settings on the battery charger to match the specifications of the battery.

   • 5

     Reinstall the battery after it is charged. Then replace the seats in the reverse order of removal.

   • 6

     Keep in mind that batteries do wear out over time. If you have completed the described procedures, and the battery still does not charge or hold a charge, it may be time to replace it.

Tips & Warnings

• Simply running your motorcycle should charge the battery. If the motorcycle can start, this may be your fastest option. If running your motorcycle does not charge the battery, there may be a problem with the motorcycle's electrical system or the battery itself.

• Battery tenders, available at most auto parts stores and motorcycle shops, are a great way to maintain the battery and keep it charged.

• These instructions are based on a Harley Davidson Softail motorcycle and are generally applicable to all motorcycles, but specific procedures will vary from motorcycle to motorcycle.

• Overcharging a battery can result in serious damage to the battery and may even result in an explosion. Know the charging specifications of your battery before attempting to charge it.

• Accidentally connecting battery cables to the wrong battery post may result in damage to your motorcycle and cause personal injury.

• Batteries contain acid which can burn skin, cause blindness and be fatal if ingested. If the battery's housing is cracked, use caution and dispose of it properly.
