How to Replace a Motorcycle

Even with the utmost care, things can go wrong mechanically with a motorcycle that puts it out of commission, like a faulty fuel filter. When problems such as this happen, it is important that the filter is replaced as soon as possible in order to prevent further damage from occurring. Motorcycle fuel filters can be located at motorcycle shops and online at eBay. Replacing the fuel filter is often a job that many motorcycle owners prefer to do themselves because it is relatively easy, and a person can often perform the work and get the bike back on the road quicker than the typical wait time for a mechanic. Knowing how to replace a motorcycle's fuel filter is a great way to save time and money as well.

Motorcycle Fuel Filter Overview

If a motorcycle begins to run sluggishly and seems like it is starving for gas, it may be a sign that the fuel filter needs to be replaced. Often gasoline from a fuel tank can pick up particles of sediment or rust, and if these elements work their way into the engine, severe damage can occur over time. Fuel filters are designed to pick up any hazardous elements and trap them before they can get from the fuel tank to the engine. It may take a while to notice that there is enough of this build-up in the filter to cause it to no longer work properly, so many people forget to check and clean it thoroughly.

There are various types of fuel filters made for motorcycles. Some bikes may have metal fuel filters while others may have ones composed of plastic.. Some filters may be round while others are square, but regardless of what they look like, the purpose is the same and so are the problems that can occur with repeated use. When large amounts of sediment and other particles build up over time that cause the engine to starve for fuel, it is often better to replace the fuel filter rather than to try to clean it.

Replacing a motorcycle's fuel filter is not a hard task if people know what to expect before getting into this type of mechanical work. Following the instructions listed below can help bikers get their fuel filters replaced quite easily and get their bikes back out on the open road.

Keep Safety in Mind

One of the very first things that anyone needs to do before working on replacing any motorcycle part that involves the fuel system is to make safety the number one priority. Fuel of course is flammable, so it should go without saying that there should never be any open flames around the fuel system when replacing a part such as a fuel filter.

It is important to take note of where the work is being performed and make sure the area is free from any type of sparks and naked flames, and also to make sure that there is no danger from lit cigarettes as well. Not only should open flames be considered hazardous, but also any environment that could produce a high heat source capable of igniting the fuel. It is also a very good idea to protect the body from the fuel that can irritate the skin by wearing protective gloves and clothing over any part of the body that may come in contact with the fuel.

Fuel Filter Replacement

Many motorcycle manufacturers recommend that the fuel filter be replaced once a year, or even earlier if the motorcycle is used on a fairly consistent basis. Replacing a used fuel filter on a motorcycle is not a long and arduous process if people know what steps to follow. There is a slight difference in the replacement procedure for a motorcycle owner who has a fuel injected engine, however the rest of the replacement process is basically identical.

Empty the Fuel Lines

One of the first things that needs to be done before replacing an old fuel filter is to make sure that the old filter and the fuel lines are run dry. This can be achieved by placing the petcock into the "on" position and then firing up the engine. Allow the bike to idle for a couple of minutes and then turn the petcock back into the "off" position.

Once the petcock is off, crank up the throttle on the bike a few times in order to push any remaining fuel out of the fuel lines and then shut the motorcycle off. Because fuel injected engines do not have fuel in the line unless the motor is running, this part of the installment process can be eliminated.

Add the New Fuel Filter

Once the lines are drained it is time to remove the attachments that hold the filter in place on each side of the hose. The attachments may consist of clips and clamps, and there may also be a mounting bracket involved used to hold the filter in place. If the motorcycle has a mounting bracket attachment, it is necessary to remove the bracket with the filter still attached. Once the bracket is removed then the filter can also be removed.

The next step is to attach each piece of hose to an end of the new fuel filter,, making sure that the filter is lined up in the right flow direction. This is not hard to determine as fuel filters typically have an arrow or other markings that tell the person installing it which end should face the carburettor. If no arrows or markings are visible, then the larger end of the filter is the one that should point toward the carburettor. If a mounting bracket is present, make sure to attach the filter securely back to the mounting bracket. Next, the clamps or clips need to be refitted to the hose and tightened enough that they are secure without damaging the hose or filter.

Test the Filter

Now that the filter is securely in place, it is time to test the filter replacement work and make sure that there are no leaks. To do this, place the petcock back in the "on" position and start the motor making sure to check for any signs of leakage from the hose or filter. If there are no signs of leakage, take the bike out for a test drive in order to get fuel back in the hose and running through the new filter.

Immediately upon returning with the motorcycle, it is important to check for any signs of a fuel leakage. If there are no leaks, then check the filter and hose a few hours later after the bike has sat idle for awhile. Anytime a fuel filter is replaced, it is always a good idea to check the work periodically just to make sure that parts such as clamps have not come loose and that the filter is operating properly. If there are still no leaks, then congratulations are in order for a job well done.

How to Buy a Motorcycle Fuel Filter on eBay

Just like any other motorised vehicle, motorcycles need to have routine maintenance in order to keep them in peak condition. Replacing the fuel filter is often a part of the maintenance procedure and luckily, fuel filters are not very expensive. Many people choose to turn to eBay when buying parts like fuel filters for their motorcycles because there are a large variety of filters available due to the high volume of individuals who advertise their products on this website.

By performing a simple keyword search, it is easy to find the right fuel filter for any bike. Simply type the keywords for the filter into the search query box located at the top of the eBay home page,, and any items that are tagged with those words are returned to you in the search results. For example, if you are looking for a Honda part, you can use keywords such as "Honda motorcycle fuel filter". Additional information about a desired item can be obtained by reading the full item description. If there are any questions about a particular item, it is a good idea to contact the seller before making the final purchase decision.

Conclusion

Many brands of motorcycles come equipped with fuel filters that help to keep sediment and other debris out of the engine. Over time, the fuel filter can become clogged and not allow enough fuel to reach the engine. If not replaced within a reasonable amount of time, the engine can starve for gas causing poor performance and possibly damage to the engine or other vital components. Because replacing the fuel filter is a relatively simple task, many motorcycle owners choose to do the work themselves.

It is always important to take the proper safety precautions when replacing a fuel filter. Making sure work is not performed in an environment where excessive heat or open flames are present can help prevent a serious injury. Wearing protective items such as gloves also helps to prevent irritation if the skin comes in contact with fuel during the replacement process. Emptying fuel from the hose and existing filter also makes the process safer, as well as making sure that attachments such as clamps are securely fastened in place once the job has been completed. Changing a fuel filter should take place at least once a year or upon the manufacturer's recommendations in order to keep the motorcycle running in peak condition.
