1978 Yamaha XS-Eleven Service and Repair Manual

Yamaha covered the XS Eleven of 1978, 1979 and 1980 in one service publication, LIT-11616-XS-12. The 1978 machine carries code XS1100E.

Working on a bike of this generation usually begins with establishing what is standard, and that is where a three-year factory book helps: the specifications and the differences between seasons sit in the same text. From there the manual gives engine and gearbox overhaul in sequence, carburettor service and synchronisation, shaft drive and chassis procedures, torque and clearance tables, and complete wiring diagrams.

Read the frame plate and confirm XS1100E before ordering. A 1981 machine takes a different publication.

The specification pages also give capacities, lubricant grades and adjustment ranges, and the maintenance chapter states the intervals Yamaha published. Troubleshooting begins from the symptom an owner reports.
