1981 Yamaha XJ650 Service and Repair Manual

Code XJ650H is the 1981 XJ650, and LIT-11616-XJ-60 is the factory book it belongs to. That publication runs from 1980 to 1982 and covers the Maxim under the same binding.

Practical use

Forty years of previous owners leave a bike in an uncertain state, so the sections that matter most tend to be the specification tables and the wiring diagrams. The former tell you what a measurement should be; the latter tell you what the loom was supposed to look like before anyone improvised. Overhaul, carburation and chassis procedures fill out the rest.

Confirm XJ650H on the frame plate before ordering.

Specification pages list capacities, lubricant grades and adjustment ranges, and the maintenance chapter gives the intervals Yamaha published when these bikes were new. Both are useful reference points on a machine with decades of unrecorded work behind it.
