1978 Yamaha EXCITER 340 Service and Repair Manual

The code to verify on a 1978 Exciter 340 is EX340E, and the manual written for it carries Yamaha part number LIT-12618-EX-41.

Because that volume was produced for the Exciter line as a whole, it covers model years 1976 through 1980 and takes in the Exciter 440 as well as the 340. A technician servicing the mid-run machine therefore has the neighbouring seasons and the larger engine on hand, which matters when a sled this old has been kept going with whatever parts were available.

Procedures include service limits and torque values, the periodic maintenance schedule, engine and carburettor overhaul in sequence, power train and track work, chassis and suspension adjustment, and electrical troubleshooting supported by wiring diagrams.

On a sled that has probably passed through several owners, the ability to check a figure against the adjacent model year is more than a convenience.
