The book and the bike
LIT-11616-01-50 is the Yamaha part number. TT500E is the model code for the 1978 TT500. Between them they settle whether this is the right reference for your machine.
Coverage is broad by design. The same volume serves the 1976 to 1981 model years and takes in the SR500 and XT500 as well, reflecting how much those bikes shared with the TT.
What you get is the dealer document: factory assembly sequences, inspection and wear limits, torque specifications at the point of use, carburettor and ignition figures, chassis and brake service, and the original wiring diagrams. Fault-finding is arranged by symptom rather than by system, which suits a bike that is usually already refusing to start.
Nothing in it has been rewritten or condensed.
