Yamaha's LIT-11616-17-13 is the service manual for the RAPTOR 50 across 2004, 2005 and 2006. The 2004 machine carries model code YFM50S.
Small machines get worked on by parents more often than by technicians, which is exactly why the factory figures help. The book gives the maintenance schedule, the carburettor settings, the spark plug specification, the automatic clutch inspection procedure, the brake adjustment values and the drive train wear limits, all as numbers rather than approximations.
Engine and chassis teardown are covered in full with exploded views, and the electrical chapter includes the complete wiring diagram along with checks for the ignition and charging circuits.
Confirm YFM50S against the frame label, since the three years in this volume use different codes.
