When the summer hits and temperatures rise, we receive more and more emails about hot Harleys. Until recently, all Harley-Davidsons® were air cooled. That means if you are not forcing air through the fins on your engine the motorcycle is not getting cooled. Most of the time this is not an issue. We start to feel the heat, especially the rear cylinder, when we get stuck in traffic and when riding on very hot days. Many new touring models come with an oil cooler or a “wet head” to help cool then engine. You have a few options to cool your Harley and Love Jugs cylinder cooling fans is one of them. Bob and Mark walk you step by step through this quick install that will help cool your hog. They start by removing the fuel tank to access the frame for the frame mount.
Bob teaches you how to service the spark plugs on your Harley’s engine. Although you can clean and service your old spark plugs, Bob recommends just buying new ones because they are fairly inexpensive. You should purchase gapped, Harley-only spark plugs which usually come with a gap of 38-43,000th of an inch. After applying some anti-seize to the threads of the new plugs, you can thread them into the cylinder by hand and tighten them with a torque wrench and you’ll be good to go.Watch Now >>
