Miscellaneous Maintenance Items

With every Harley Davidson maintenance interval – inspect, tighten, top off or replace any hose, cable, filter, bushing, fluid and critical fastener that appears dirty, damaged, low or loose. Take your time and work your way over the motorcycle systematically so that no component that is critical to safe operation is overlooked.

harley davidson motor oilI log an average of 12,000 miles a year on my Harley Davidson, and since the 10,000 mile maintenance, I began changing the oil and filter every 2,500 miles. In my opinion the oil gets way too dirty to keep in the engine for 5,000 miles at a time. Even multi-cylinder, liquid cooled cars recommend changing the oil every 3,000 miles. It’s a small price to pay to keep your air cooled Harley protected.

Having made several attempts to clean the air filter element in my Sportster, I decided to replace it at 5,000 mile intervals. The air filter element never cleans properly and the element fibers get matted down from the recommended cleaning process. Priced at about $25.00 from the dealer, the air filter element is a bit pricey, but the noticeable increase in performance and fuel economy make it a worthwhile investment.

** Since paying the Harley Tax, I now have a K&N high flow air filter element that does clean as advertised.
