Detailed workshop manual for the 1974 Kawasaki MT1-B off-road motorcycle. Complete coverage of the 99cc two-stroke reed valve engine, CDI ignition, 6-speed transmission, suspension and brakes. Provides factory specifications and professional-grade repair procedures for vintage Kawasaki enduro enthusiasts.
1974 Kawasaki MT1 Service Manual
VEHICLE/EQUIPMENT INTRODUCTION:
The 1974 Kawasaki MT1-B continued the popular compact enduro line established the previous year. As Kawasaki s smallest off-road offering the MT1-B featured Kawasaki s refined two-stroke engine technology in a lightweight trail-worthy chassis. The engine used a reed valve induction system for improved throttle response compared to older piston-port designs and CDI ignition for reliable spark performance in all weather conditions. The MT1-B was commonly used on family ranches for light utility work on farm property inspection and by young riders entering the sport of off-road motorcycling. This workshop manual provides complete factory service data for proper maintenance and repair.
SERVICE AND REPAIR SCOPE:
- Two-stroke single-cylinder engine complete teardown and rebuild

- Exhaust port decarbonization procedure
- Carburetor disassembly ultrasonic cleaning and reassembly
- Reed valve block inspection for cracked or delaminated petals
- Ignition timing with static timing method using test lamp
- CDI ignition module resistance testing and coil diagnosis
- Clutch center boss wear driven plate warpage measurement
