If you are a Harley Davidson Switchback owner, you know it combines the power of a touring bike and the versatility of a cruiser. But even the best bikes have their issues, and the Switchback is no different.

So, what are the most common problems in Harley Davidson Switchback bikes? Excessive vibration is the primary problem that plagues Harley Davidson Switchback bikes. This often happens at high speeds, typically 2800 RPM. In addition, the cam chain tensioner is more prone to wear. Also, earlier models suffer premature brake master cylinder failure.

We’ll look at the most common problems Harley Davidson FLD Dyna Switchback owners face and how to fix them. Read on to find out how to troubleshoot your Switchback’s problems.

In-Depth Discussion of the Most Common Harley Davidson Switchback Problems & How to Fix Them

Now let’s have a look at the details of the problems below.

1. Excessive Vibrations

Harley Davidson Switchback owners are no strangers to the excessive vibration problems that often occur at high RPMs. Many riders have experienced the dreaded “shudder” feeling upon hitting 2800 RPM.

This problem can be quite a nuisance, causing various parts to become loose over time, such as the saddlebag seat and your rearview mirror. Also, it affects riding comfort and the ability to control the bike better.

  • The Dyna Switchback’s 2-in-1 exhaust setup is to blame for excessive vibrations.
  • However, the trade-off is a small diameter opening. And it struggles to dissipate smoke from the engine, leading to frequent clogs. Eventually, the clogs obstruct the exhaust fan, increasing vibration and muffling the noise.
  • Moreover, dual muffler designs tend to overheat, putting more stress on the exhaust components, including mounting bolts. This makes them loose over time, leading to vibrations at high speeds.
  • Also, the Switchback doesn’t have counter balancers responsible for nullifying vibrations. Instead, it has a rubber mount to isolate engine vibrations. Over time, the mounts become loose, causing vibrations.

How To Fix

First, locate the mounting points of the exhaust system that are causing the vibration. You can do this by starting your motorcycle and feeling for the excessively vibrating areas. Once you have identified the problem areas, you can try the following:

  • Use rubber washers or grommets to dampen the vibration. Simply place the washers or grommets between the exhaust mount and the frame of the motorcycle. Also, you can use a clevis pin fastener to retain the coil spring in position so that it can do its job of dampening the vibrations.
  • Use an exhaust wrap. This heat-resistant material can be wrapped around the exhaust pipes to reduce vibration and noise.
  • Try tightening the mounting bolts on the exhaust system. This may help secure the system more tightly to the motorcycle’s frame and reduce vibration.

If none of these DIY solutions works, you may need to consider replacing the factory mount setup with an aftermarket exhaust mount that is designed to reduce vibration.

Consider the Davidson Vance & Hines Twin Slash Dual Exhaust. It offers the performance of a 2-in-1 exhaust but with a generous exhaust pipe diameter.

2. Cam Chain Tensioner Wear

This issue was inherently problematic on Harley’s pre-2006 bikes due to the design of its cam chain system. Poorly engineered plastic shoes that travel along the chains tend to wear out prematurely.

Harley implemented the 103 Twin Cam hydraulic tensioner on the Switchback models to fix this problem. However, it has not proven to be a permanent solution. In fact, a study shows that cam chain tensioner wear contributes to Harley’s  Switchback vibrations.

How To Fix

  • Professionals suggest converting Twin Cam engines by gear drive replacement is the best course of action. Many gear systems are available to tackle the issue head-on.
  • Likewise, instead of replacing the gears, you can also extend the lifespan of your Twin Cam by investing in higher-quality oils. Although it may cost you more in the short term, it is still cheaper than a complete gear replacement.
  • Installing Harley’s fan-assisted oil cooler is perhaps the most effective method for dealing with the problem as well. The fan provides an uninterrupted air stream, cooling the engine and decreasing wear.

3. Brake Master Cylinder Failure

The brake master cylinder is a critical braking system component that generates hydraulic pressure to actuate the brake calipers or drums. Over time, the rubber seals and components inside the master cylinder can degrade, leading to leaks and pressure loss.

This can cause a decrease in braking performance or complete brake failure. Accordingly, earlier Dyna Switchback motorcycles are more prone to brake master cylinder failure.

Brake master cylinder failure is a tech-related issue. Early Switchback versions suffer from bad hydraulic ratios, leading to a lack of braking power and poor brake feel.

The hydraulic ratio refers to the size of the master cylinder compared to the size of the caliper pistons. If the ratio is not properly matched, the hydraulic pressure required to activate the caliper pistons may be too high. And that leads to frequent brake master cylinder failure.

How To Fix?

Replacing the Master Cylinder: The solution can be as easy as replacing the rubber seals on the brake master cylinder. However, if the master cylinder is worn out or broken, the only fix is to replace it.

You can downsize the brake master cylinder when replacing it to improve the hydraulic ratio and provide greater braking force. Downsizing the master cylinder can increase pedal travel and provide less pedal effort.

Generally, regular maintenance and inspection can help prevent brake master cylinder failure. Harley Davidson recommends flushing the DOT 4 brake fluid every two years and inspecting the brake system regularly for leaks, wear, and proper function.

Upgrade to a larger saddlebag: Depending on the model of your motorcycle, there may be larger saddlebags available that will better suit your needs. Check with your local Harley Davidson dealer or online to see what options are available.

4. Small Saddlebags

It’s worth noting that some riders prefer a minimalist look on their bikes and may prefer smaller saddlebags. However, most riders find the Switchback saddlebags too small for their storage needs. They don’t  hold as much gear as other larger saddlebags, such as those in Road King or Street Glide bikes.

How To Fix

  • Upgrade to a larger saddlebag: Many aftermarket saddlebags may provide more storage space. However, ensure it’s compatible with your Harley Davidson Switchback model.
  • Use a tail bag: Another option is to use a tail bag, which attaches to the rear of your motorcycle seat. This can provide additional storage space for items that won’t fit in your saddlebag.
  • Pack smarter: Finally, you may be able to fit more items in your existing saddlebag if you pack smarter. Also, consider streamlining your packing to bring only the essentials on your rides.

Harley Switchback 103 Twin Cam Engine Reliability

The 103 Twin Cam engine is a reliable Harley-Davidson powerplant. It can deliver a smooth and powerful ride and is relatively low maintenance, with minimal parts to replace and repair.

However, there are mixed reactions regarding Harley’s 103 Twin Cam engine. In fact, some customers sued Harley saying the engine emits high heat, often causing a burning sensation and shortening engine life.

However, the high heat problem only happens after riding for hours. Plus, you can install cooling deflector wings as a permanent solution.

Switchback’s 103 engine isn’t the only Twin Cam in Harley’s lineup. There are other variations, including the 88 (released in 1998), 95 (released in 2000), 96 (released in 2007), and 110 (released in 2012) models.

Some offer stellar performance; others are not so good. Hence, knowing which Harley Twin Cam years to avoid is very important.
