81-83 SUZUKI GS450T: Clymer Service Manual Clymer motorcycle repair manuals are written specifically for the do-it-yourself motorcycle enthusiast. Whether it's routine maintenance, troubleshooting or more extensive repairs involving engine and transmission overhaul, Clymer manuals provide the information you need to maintain and repair your motorcycle. The step-by-step procedures, detailed photos and extensive exploded parts views in each manual are based on the complete disassembly of the bike. Unlike the O.E.M. factory manuals, which are designed for the professional motorcycle mechanic, Clymer shop manuals are designed specifically for the first time user.
