A single fire ignition means improved performance of your Harley EVO. The Harley Evolution motorcycles use a single fire ignition system. It will help lower the engine’s rpm, which is beneficial for limiting backfire. Single fire ignition is also more reliable and efficient at lower engine speeds, because it only fires the spark plug when the cylinder is ready. It’s a better choice for riders who ride their motorcycle every day and don’t want to worry about having to change the fuel. Get the best single fire ignition for Harley Evo from the following top-sold units.
Benefits of a Single Fire Ignition on Your Evo
This modification is an easy and straightforward process. Once you have installed the new coils, you’ll need to route the wiring for the new dual coils. The ignition will start immediately after installation and the engine will settle to a smooth idle. The throttle response is a lot smoother and the power output is slightly higher than before. You’ll feel a lot of power in top gear. Acceleration uphill is more positive and the feeling is steady and predictable. Rolling on in top gear never felt hesitant, even when accelerating uphill.
Single Fire Ignition vs Dual Fire Ignition
The difference between single and dual fire ignition is largely cosmetic. In terms of horsepower, single fire ignition is smoother and easier to start. Moreover, it produces less backfiring. Although some people talk about coil saturation, it doesn’t seem to cause any issues for most riders in a normal rpm range. Furthermore, a wasted spark in the cylinders during the compression stroke is not a problem. Therefore, single fire ignition is generally favored by most.
Best Ignition For Harley EVO Buying Guide
Getting the Best Ignition for Harley EVO is not difficult if you follow the above mentioned tips. However, you should be aware of certain issues before you proceed. Before purchasing a new ignition system, you must identify the type of your bike. For instance, a bike with a breaker type ignition system may have an older coil, which can be replaced with the latest coil. The instructions for the upgrade are easy to understand, but you should identify the exact make and model of your bike.
An ignition module is responsible for firing the spark plugs. This module conducts data from a shaft sensor and a camshaft sensor. It then evaluates when each spark plug is firing. To avoid the possibility of misfire, you should monitor the hole in the spark plug and its piston. It should be at the center of the pit. The timing should be just marginally perfect. However, if you don’t do this, you could end up damaging the ignition system.
If you notice any excessive heat coming from the spark plug, your mixture is too lean. To make sure your ignition system is functioning properly, make sure to replace the spark plug at least once every fifteen thousand to sixteen thousand miles. Replacing the spark plugs will improve the starting and running of your bike. You may also want to opt for high-quality spark plugs if you want to preserve its efficiency. While high-end spark plugs will not make your bike run better than it did when it was new, they will definitely prolong its life span.
How to Test a Coil on a Harley Evo?
If you’ve noticed a strange noise or feel like your motorcycle has lost power, it could be a bad ignition coil. This will likely be noticeable by rough idling or jerking. It might also seem like power is missing when you try to accelerate. It might stall while working or produce black smoke. Or, it might stop working completely. If you notice any of these problems, it might be time to get to the bottom of the problem.
First, you should plug in the wire from Pin#11 into Pin#29. Then, you should flip the Run/Stop switch to OFF/STOP. You’ll need to briefly activate the RUN switch. This will charge the front cylinder coil, firing the front spark plug. A blue spark should be present when the ignition is working properly. Otherwise, a yellow spark will indicate low power.
If the reading is too low, try replacing the ignition coil. To do this, you need to disconnect the ignition coil from the wiring harness. Next, disconnect the smaller wires and the secondary windings. Connect your ohm-meter to the points on the coil where the wiring harness connects. The resistance of the primary coil should be around 2.3 ohms. Using a meter with a higher reading will give you an idea of which coil is bad.
If you have an ignition coil issue, you may also notice the engine light coming on. A diagnostic tool will give you a code for P0351, which refers to a primary circuit malfunction. Then, you can test the coil with a temporary replacement. The whole process should take about 15 minutes. To do this, you’ll need to have access to an Ohmmeter and SAE wrench set. And remember that you will need hands to disconnect the plug wires.
How to Set the Timing on a Harley EVO?
To advance your motorcycle’s timing, raise the RPMs. To center the timing plate, loosen the standoffs underneath the flywheel. You should see a small vertical line through the timing hole. Once the mark is in the timing hole, advance the timing until it passes through the right spot. Once you’ve centered the mark, you’ve made the adjustment. To adjust the timing, turn the rear timing plate counterclockwise until it aligns with the center one.
Next, remove the timing cover and turn the ignition switch to ACC. You should notice a yellow mark. This is the timing advance. This is the mark that indicates when the timing is correct. Make sure the mark is exactly in the center of the hole. After that, tighten the stand off bolts. Then, rotate the timing plate counterclockwise until it matches the timing light. Make sure the mark is within two degrees of the correct timing.
The timing light should be located next to the TDC mark on the flywheel. The timing mark can be easily identified with a plastic drinking straw. To get a clearer picture, turn the engine until the front piston is at TDC. The rear wheel should start bumping, indicating that the piston is at TDC. The figure 8 mark will appear on the flywheel when the rear wheel starts its compression stroke.
