Quick answer

Service Bulletin M-1444: 2016 TOURING, TRIKE, CVO CENTER FILL FUEL CAPS - OWNER NOTIFICATION OF DIFFICULT TO REMOVE OR INSTALL FUEL CAPS. Harley-Davidson has determined that some 2016 Touring, CVO Touring or Trike models equipped with center-fill fuel tanks may develop a swelling issue between the fuel tank fill neck and the threads on the fuel cap when exposed to certain types of fuel and environmental conditions. Harley-Davidson is conducting a notification by mail to U.S. and Canadian owners of record to inform them that if they have a fuel cap that requires extreme effort to install or remove outside of the original two-year Harley-Davidson Limited Warranty, it may qualify for repair coverage under the Harley-Davidson Emission Control System Limited Warranty.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
