NHTSA's summary

SERVICE BULLETIN M1123: 49 STATE/CANADA RECALL 0603 - CARBURETOR JET NEEDLE REPLACEMENT. PURPOSE: Revision. As recently advised in the May 29 Dealer Communications, Harley-Davidson has learned that certain 2002 carburetor equipped Dyna and Softail model motorcycles do not meet portions of Canadian, U.S. and California air quality regulations. In the interest of regulatory compliance, as well as customer satisfaction, Harley-Davidson has elected to initiate a voluntary recall (Noncompliance Recall Code 0603) to replace the carburetor jet needle in all affected motorcycles.
