5 Possible Dyna Super Glide Problems & Fixes 

After exploring Harley Dyna deeply, we found that some users have reported engine wiggle, slower acceleration, an overstretched cam chain, and vibrating unit issues. A few users also shared problems with the transmission and starter.

Luckily, most of these issues are solvable with some tweaks at home. And some of the units require repairing to maximize the riding experience. Let us get you covered with their quick fixes right here!

Quick Fixing Chart For Dyna Super Glide Problems

Just because Harley has launched custom-specified Dyna Super Glide bikes does not mean they are not prone to system failure! Usually, they deliver 18000 to 20000 miles without issues. 

But, these bikes tend to act up with time. So before we get into the details, here is a fixing chart of the malfunctions:

Troubleshooting and Fixing for Dyna Super Glide Problems

Dyna Super Glide models from Harley generally fuel the passion of bike owners with their great performance. 

However, our research says that some of its owners have reported issues with it. Fortunately, you can work around these problems. So, we have listed these issues with their quick fixes:

Frequent Vibrations

Vibration while riding the bike is common in the 2004 Dyna super glide models. Once these bikes drive up to 20000 miles, their exhaust pipes start vibrating. 

This causes the saddle to shake as well. As a result, riders cannot sit comfortably. It is usual for these motorcycle units to shake as they age. 

However, if for some reason the exhaust system loosens and hangs down, it will trigger rapid movements throughout the bike. With such increased movement, it is not possible to enjoy a bump-free ride. 

If you can see a loose hanger clip underneath the exhaust system, try to reattach it. It is better to replace the hanger with a new one. 

Even if it does not prevent the exhaust from shaking, we prefer getting a new exhaust system.

Power Loss

The 2006 super glide bikes provide great acceleration and speed. But, in the discussion forum, we noticed that many of its users discussed its slow speed and power loss issues. 

And most of their models are several years old that have reached 18000 miles or above. 

Such power loss holds the bike from speeding to the up hills. Therefore, riders cannot accelerate properly, plus, the engine shakes up and down or side to side. 

The worst is that the bike can start going downhill. Changing gear often settles down the issue. Also, turning the engine off for a while and starting it again resolves the low speed and acceleration

Just a reminder, if the issues persist, contact a mechanic to diagnose and repair the faulty units.  

Starter Issue 

Harley bikes and their engines have overheating issues, especially if you drive for quite long trips. Such a temperature rise causes the engine to detach from the fuel tank and starter. 

Because of the disconnection, it gets difficult to keep the engine running for a long period. Thus, it keeps turning off after it starts. 

Seasoned mechanics often suggest changing the spark plugs and starter system wiring to fix the starter problems. Additionally, many users have replaced the fuel pack to get rid of the bummer.

Faulty Cam Chain

The cam chain of the Super Glide bikes can overstretch or loosen up on account of overheating and high pressure. 

So, the chain will hang downwards from the bike. And a loose cam chain skips gear that may lead to a misfire. Also, you will have a hard time starting the engine quickly! 

Sometimes, the cam chain can tighten and decrease the slack or the space between the crankshaft and the chain. 

A tightened chain causes the engine oil to overheat and leak. Also, these chains tend to drop the RPM rate. And firm chains wear out quickly. 

We advise you to stick to the cam chain slack or space mentioned in the owner’s manual to prevent the chain from hanging or getting too tight. 

After parking the bike, loosen or tighten the chain as per the manual. Nonetheless, if the chain has rust build-up, getting it replaced will do the work. 

Malfunctioning Transmission

Dyna Super Glide transmission manufactured from 2006 to 2017 can malfunction over time. Besides, lack of maintenance can cause the same issue! 

Once it malfunctions, riders will struggle to shift gears while approaching uphill. Consequently, the engine loses torque and provides insufficient power to reach the hill steadily. 

A faulty transmission overheats often, and the heat spreads to the fluid. Excessive heat in the lubricant triggers it to burn and leak. 

Changing or adding transmission fluid can keep the transmission active. If that does not work, we do not see any better alternative than replacing the transmission to increase engine efficiency and fuel economy!
