The 2007 Harley Softail Custom is an iconic motorcycle that has gathered considerable attention for its distinctive style and powerful performance.
However, like any mechanical equipment, it’s not devoid of issues.
In this article, we will dive into some common problems faced by 2007 Harley Softail Custom owners.
We will also explore the potential solutions and preventive measures to ensure an optimal riding experience.
2007 Harley Softail Custom Problems
One of the most frequently reported issues is related to the bike’s electrical system, particularly the stator, which can burn out and lead to a dead battery or poor engine performance.
The second common problem lies in the cam chain tensioner, which has a tendency to wear out prematurely, potentially leading to significant engine damage.
However, some riders have experienced issues with the bike’s fuel system, specifically with a faulty fuel pump causing inconsistent fuel supply to the engine.
1. Battery Issues
One of the most common problems encountered by riders is battery-related issues.
These typically result in the bike struggling to start or not starting at all. The underlying issue can often be traced back to a drained or faulty battery.
To diagnose this problem, start by checking the battery’s voltage using a multimeter. A healthy 12-volt battery should read between 12.4 and 12.7 volts.
If the reading is below 12.4 volts, it’s a sign that your battery may be undercharged.
This is often due to prolonged periods of inactivity where the bike isn’t running, allowing the battery to slowly lose charge.
If your battery is undercharged, you can try charging it using a battery tender.
However, if, even after charging, the battery cannot hold the charge or the voltage reading is still below the acceptable range, it’s a clear sign that your battery needs replacement.
While replacing the battery, make sure to opt for a high-quality one. Cheaper alternatives may seem appealing, but they can often lead to more problems in the long run.
2. Unusual Noise
This noise often presents as a loud knocking or pinging sound, particularly noticeable when the motorcycle is in motion.
Several factors can contribute to this issue, such as poor fuel quality, valve train problems, or even a failing drive belt.
To diagnose and tackle this problem, begin by inspecting the fuel system. Ensure that you’re using high-quality fuel, as low-quality or contaminated fuel can cause engine pinging.
Next, check the valve train components, including the pushrods, rocker arms, and lifters, for wear or damage. A malfunctioning valve train can result in a loud knocking sound.
Lastly, inspect the drive belt. Over time, the belt can wear out or become loose, leading to unusual noise.
If the belt appears frayed or shows any signs of damage, it may need to be replaced.
As always, if you’re not comfortable performing these checks yourself, it’s best to take your motorcycle to a professional mechanic.
3. Torque Management
The 2007 Harley Softail Custom is equipped with Electronic Sequential Port Fuel Injection (ESPFI), which also manages the torque output.
This system offers precision in fuel delivery, improving overall performance and efficiency. However, some riders have reported issues related to torque management.
The main problem seems to be a sudden reduction in power when they’re accelerating, which could be due to the torque management system cutting power to prevent potential damage to the engine.
This management system is designed to protect the engine’s drivetrain from the stress of high torque, but it can sometimes be overly cautious, leading to a frustrating riding experience.
Now, if you decide that you’d like to bypass this torque management feature, it’s important to note that this should be done with extreme caution.
To do this, you will need a tuner, a device that modifies the engine control unit’s (ECU) parameters, including torque management.
You can purchase a tuner from various aftermarket parts suppliers. Once you have the tuner, connect it to the motorcycle’s ECU, usually found under the seat or the fuel tank.
Follow the instructions provided with your specific tuner to modify the torque management settings.
Remember, altering these settings can increase the risk of damage to your motorcycle’s engine and void any existing warranties.
4. Bad Speed Sensor
The speed sensor, officially known as the VSS, is responsible for sending speed data to the motorcycle’s computer.
Which governs functions such as fuel injection, ignition timing, and transmission shift points.
When the VSS malfunctions, you may experience symptoms like erratic speedometer readings, poor performance, and abnormal shifting.
The motorcycle may also stall or fail to start, as the Harley’s Engine Control Unit (ECU) no longer receives accurate speed data.
To address a faulty VSS, follow this guide:
- Look for a speed sensor, which is typically located at the rear of the transmission on the Harley Softail Custom.
- Look for any obvious signs of damage, such as frayed wires or a cracked sensor casing.
- Disconnect the VSS cable and clean the connector with an electrical contact cleaner.
- You can test the VSS using a multimeter. A healthy sensor will generally read between 500 and 700 ohms.
- If the VSS fails the multimeter test or if cleaning doesn’t resolve the issue, it needs to be replaced.
- Ensure that you buy a genuine Harley-Davidson speed sensor for the best performance and fit.
5. Oil Leakes
Often, these leaks originate from the base of the push rods due to worn-out O-rings.
If left untreated, oil leaks can lead to a reduction in engine performance and potential damage due to inappropriate lubrication.
Here’s a simple guide on how to address this issue:
- Clean the oil-covered area and then start the engine, looking closely to detect the exact leaking point.
- Once you’ve identified the leak, remove the push rod cover. This typically involves loosening the bolts and holding the cover in place.
- After removing the cover, you should see the O-rings. Replace them with new ones, ensuring they are the correct size for your specific model.
- Once the new O-rings are in place, reassemble the push rod cover. Make sure to tighten the bolts to the manufacturer’s recommended torque.
- Finally, run the bike to ensure the leak is fixed.
Remember, always consult with a professional mechanic if you’re uncomfortable performing these procedures yourself.

2007 Harley Softail Custom User Reviews

“Purchased mine used on Sept 8th 2011. Since then I have put over 20k on it, (it had 4571 miles on it when I got it). Made several long rides on it of over 1k miles round trip on 3 different occasions and have never been let down by it. The 96 CI engine is fantastic and the 6th gear makes long trips very efficient on fuel. Have always averaged over 43 MPG even with daily commutes to and from work and in town. My only knock on the bike was the cost of the rear tire. The 200/55 skin isn’t cheap and hard to find in that size. My buddies who all have bigger baggers have told me from the beginning that I would eventually be trading up for more comfort, but I don’t see it happening. This bike is that comfortable and let’s face it, it LOOKS like a bike should and not a two wheel car. Keep the wheels down and enjoy the ride.”

“Since childhood I was a BIG Harley fan,...but never thought I was going to own one. Finally I could afford my first Harley, a 1200 low Sportster. This was an excellent machine to start off with, but I always had a certain picture in my mind of how a Harley must look, i.e. trading in my sportster for the 2007 softail custom. I love this bike to death. Lotsa power, comfort, looks,sound and feels GREAT!! There is nothing that can describe the feeling you get when firing up your HOG and tackling the road.
