2024 Yamaha UMAX 1 EFI Service and Repair Manual

Yamaha's 2024 service volume for the UMAX line is LIT-19616-A3-12, and the UMAX 1 EFI appears in it under code YUM1A24.

Eight 2024 UMAX configurations share that book, EFI and electric alike, which is how Yamaha documents a family that splits mainly by drive system and body. The shared chapters, chassis and body panels, brakes, steering, suspension, are written once and apply across the group.

EFI-specific coverage

• Fuel injection system testing and fault codes
• Engine removal, teardown and reassembly
• Ignition and charging system checks
• Clutch and drive belt service

Torque figures and service limits accompany the procedures, and the wiring diagrams cover the harness as built. Check YUM1A24 against your vehicle identification before working from a specific page, and quote it with the part number when ordering.
