1987 Yamaha YAMAHOPPER Service and Repair Manual

Last of the run documented in this volume, the 1987 YAMAHOPPER carries model code QT50T. Yamaha's manual for it is part number LIT-11616-QT-50, shared with the 1984, 1985 and 1986 machines.

A four-year book suits a machine that was built with few changes. The procedures are written once, in the order the factory intended the work to be done, and the year-specific notes appear where they are needed rather than in a separate appendix.

Expect torque specification tables, wear and service limits for the parts you are meant to measure, carburation and ignition settings, complete disassembly and reassembly sequences, and the wiring diagram for the harness as delivered. Confirm QT50T on your frame label before buying so you know the book matches the bike and not just the name on the tank.
