Preparing to Clean the Fins
Having a Harley is not only a source of pride, but also an investment. Keeping it in good condition, especially the engine, is integral to safeguarding that investment and reviving the beauty of your Harley. The first step in doing so is to clean the engine fins of dirt, debris, and other particles.
Luckily, there are several tried-and-true methods for successfully removing these materials from the fins. First, you’ll need to use either a cleaner, a brush, or fine wet dry sand paper to scrape off any large pieces of debris. Then you should mix equal parts vinegar and water in a spray bottle and spray it on the fins until they’re saturated. Finally, use a mild soapy solution (or just regular soap) along with a sponge and warm water to remove any remaining dirt or grime.
Now that your engine fins are good as new, you can take pride in your Harley—and ride knowing it’s protected.
Gently Remove Caked-on Dirt and Debris
If you’re like most Harley riders, your pride and joy has some areas of caked-on dirt or debris. Don’t worry—there are a few ways to gently lift it away.
First, reach for a can of WD-40 or penetrating oil. Apply the product directly to the affected areas and let it sit for a few minutes. This will help loosen any contaminants that may be stuck to the metal surfaces of your engine fins. For tougher deposits, you may opt for special bug-and-tar remover foam products that can be found in most auto supply stores.
Once the dirt has been loosened, you can use a wire brush or rag to remove any rust and debris from the metal surfaces of your engine fins. Make sure to use gentle motions so as not to damage any other components in the process. It’s also important not to use too much pressure when cleaning; doing so could strip away some of the metal’s protective coating, thereby accelerating its corrosion over time.
Use a Foam Cleaner for Stubborn Stains
The next step in reviving your Harley’s engine fins is to address any stubborn stains. For this, you’ll need a foaming cleaner that can penetrate grease and grime and is tough enough to remove ground-in dirt without damaging the delicate surfaces of your engine fins.
We recommend our Foaming Heavy Oil Stain Cleaner—it’s designed with motor oil in mind, so it’ll do the job nicely. Here’s how to use it:
- Start with a gentle wash of soap and water
- Apply the Foam Cleaner directly onto the stained area
- Let it sit for 3-4 minutes
- Scrub gently until stains disappear
- Rinse off with water, then dry with a clean cloth
- Reapply Foam Cleaner as needed
Rinse and Dry Thoroughly
Once you’ve brushed your Harley’s engine fins and removed all the grime, it’s time to rinse. Start from the bottom and work your way up so that no residue gets pushed down into any crevices or corners. Make sure you get every nook and cranny.
It’s important not to let the soap sit too long before rinsing – otherwise it can damage your bike’s paint job. Once you’re satisfied that your Harley is fully clean, reach for a quality microfiber cloth and give it a thorough drying. Once dry, protect your bike with a wax detailer that has UV protection – this will keep those engine fins looking beautiful for the long haul.
Utilize a Detail Brush for Hard to Reach Areas
When it comes to cleaning Harley engine fins, you’ll want a detail brush. A good detail brush will help you get into all the crevices and cracks of your Harley’s engine.
You can find detail brushes in almost any automotive store, in various sizes and shapes for different purposes. These brushes are a great choice since they have soft bristles and plastic handles that won’t harm your engine.
Different Sizes & Shapes
Detail brushes come in a variety of sizes and shapes, so you’ll want to make sure you have the right one for your situation. The smaller and thinner brushes are ideal for tight clearances, while the larger ones can be used to clean surfaces or exterior cracks.
Soft Bristles & Plastic Handles
Detail brushes feature a soft bristles that won’t scratch the metal surface of your motorcycle engine fins. There are also plastic handles so don’t cause any harm to the finish as well.
It’s important to use the right brush for your cleaning job; otherwise, you may damage delicate parts or cause unintended scratches and dents. With a detail brush specifically designed for harley engines, you can clean those hard-to-reach areas with ease.
Examining Your Engine After Cleaning
Now that you’ve finished cleaning your Harley’s engine fins, it’s time to examine your work. This is a great opportunity to spot any potential issues with the engine before they become a problem.
When looking over your recently cleaned engine, pay attention to the following:
- Oil level – Make sure it’s where it should be.
- Accessory belts – Check for signs of wear and tear.
- Cylinder heads and blocks – See if they are free of corrosion and residue.
It may also be worthwhile to take the time to clean up any parts that have excessive dirt or grime on them. This step is especially important if you used a degreaser—make sure you allow it to sit for at least 3-5 minutes before rinsing off. Doing this allows any accumulated grease or oil on the engine fins to break down, which gives you a better chance at removing them.
By cleaning and examining your Harley’s engine fins regularly, you’ll help keep its performance running smooth for years to come.
