1981 Yamaha XS400 SPECIAL II Service and Repair Manual

Model code XS400H identifies the 1981 SPECIAL II, and the service reference is Yamaha part number LIT-11616-XS-42.

That single book was written to span 1976 through 1982 and to take in the XS360 and the standard XS400 as well as this machine. For a bike now several decades old, the wider scope is an advantage: when a previous owner has fitted a component from a nearby year, the tables let you compare specifications instead of assuming they match.

How the manual is organised

General information and specifications come first, then periodic adjustment, then engine overhaul, chassis, and electrical. Each repair section gives the order of operations, the tools the factory used, and the torque or clearance to meet on reassembly. Troubleshooting is arranged by symptom, so a hard-starting or charging complaint leads to a sequence of checks rather than a parts list.

Verify XS400H before ordering.
