5 Warning Signs Your Motorcycle Needs a Service Appointment

 

Expensive, major repairs for a bike typically don’t come out of nowhere. It starts with a small, odd noise or something that just doesn’t feel right. If it’s ignored, that tiny issue does turn into a much bigger issue – and much more expensive repairs.

What are the signs my motorbike needs a service? There are a number of signs to watch out for to make sure the bike is in good condition and to catch potential problems early. At the first sign that anything is wrong, it’s a good idea to take the bike to get it serviced right away. Some of the things to watch out for include the following.

Any Unusual Noises

A strange noise can vary from a chain hitting something it shouldn’t to a major internal issue because of worn parts. When there is an unusual noise, it’s always a good idea to have the bike inspected to find out what’s wrong. Maybe it’s a quick and easy fix, but whatever it is, it’s only going to get worse over time.

If there are any strange noises, try to note when they happen and what the sound is like. This can help the mechanic figure out what’s going on with the bike. If possible, try to get a video of the sound so it’s easier for them to listen to what’s happening, especially if it only happens periodically.

Note whether the sound happens only at high speeds, only when starting the bike, or only after a long ride, as all of these can help make sure the mechanic can repeat the issue in the shop to discover the cause.

Fluids Puddling Under the Bike

There should never be fluids puddling under the bike, so if you notice something dripping or a larger puddle before a ride, take the bike in to be fixed right away. It’s not a good idea to ride it in this situation, as riding without the proper fluids can cause far more serious damage. Even if you top off the fluids, depending on how bad the leak is, more damage can occur on the way to the shop.

Take note of the color and smell of the liquid before going to the shop if you aren’t sure what’s leaking. If it’s a darker color, it may be oil. If it’s clear, it’s likely brake fluid. It could also be coolant or other fluids used for the bike. A mechanic can take a look at everything to find out why the bike is leaking and what’s needed to get it back on the road again.

Harder to Start than Normal

You hop on the bike, ready to ride, but it doesn’t start on the first try. It may struggle and slowly get started, or it may completely fail. Trying again gets it to run, but don’t ignore it. Sure, it worked this time, but it’s a sign that something’s wrong and it needs to be fixed before it does fail to start.

Common issues that can cause it to be harder to start than normal, or fail to start completely, include issues with the battery, the starter, or the fuel system. Having a mechanic take a look can help you get to the bottom of the issue before you’re away from home and stranded with a bike that won’t start at all.

Feels Different When Riding

Trust your gut. Does the bike feel a little different when riding it than it used to? This could be the first sign that something just isn’t right, and if it’s not fixed, you may end up looking at motorcycles for sale to replace it. Instead, trust what you feel and take the bike in to be seen by a mechanic. Your instinct could be noticing something subtle that could turn into a major issue if it’s not fixed right away.

If there are issues like a drop in acceleration, trouble rounding corners, or anything else that makes the bike a little harder to handle, it’s time to take it in right away. These may require immediate attention to ensure you are safe when you ride the bike. Always consult a mechanic at the first sign of an issue, before getting back on the bike, to help prevent an accident or major breakdown.

Visible Wear on the Bike

Visible wear on the outside of the bike may just be a sign that it’s getting a little bit older and a little more well-loved from all the trips you take. However, wear can indicate that the bike does need to be inspected for potential issues. While wear on the outside is normal, it could indicate more wear on the internal components of the bike, which can lead to more costly issues down the road.

Before riding, it’s a good idea to inspect the bike for wear on the tires. Make sure they have enough tread to handle the ride ahead, and have them replaced if they’re looking a little worn. It’s also a good idea to keep an eye on other components, like the brakes, too, as they do need to be replaced regularly. Doing this can help prevent potential issues or accidents in the future.

However, even if the brakes are good and the tires are fair, if the bike is looking a little worn, make sure to take it in for regular maintenance. A mechanic will look at the internal components for any signs of wear and tear. Fixing them when wear and tear is first noticed is often a lot less expensive and can prevent you from having a bike that doesn’t run.

If your bike seems to be a little harder to stop or you feel like something isn’t handling quite right, don’t ignore your gut instincts. Take the bike in for a service appointment right away. With how often you ride the bike, you know what it should feel and sound like, so when you notice something is off, it’s a sign that there could be an issue. Getting it fixed now can help you save money in the long run.
