The 1980 Exciter 440 wears the code EX440G. Its factory service manual is Yamaha LIT-12618-EX-41, the same volume that serves the 340 and every season from 1976 onward.
By the final year of the run the documentation had settled into one book covering 1976 through 1980 for both engines. An owner of a last-year machine therefore gets the earlier specifications as well, which helps when tracing a revision or identifying a part fitted somewhere along the way.
Repair coverage takes in service limits and tightening torques, the periodic maintenance schedule, engine and carburettor overhaul, power train and brake adjustment, chassis and steering work, and electrical diagnosis with wiring diagrams. Confirm the code and the part number against your machine before ordering.
