Clymer Motorcycle Repair Manuals Unlike factory manuals, Clymer motorcycle manuals are written specifically for the do-it-yourselfer. During the production of a Clymer

motorcycle repair manual, techs completely disassemble and reassemble the machine and provide easy-to-follow instructions that allow novice users to safely and efficiently service and repair their motorcycle - in a real setting - not the ideal setting of a professional technician in a fully equipped shop. It is this very experience that sets a Clymer motorcycle repair manual apart from its factory counterparts.
