Yamaha VMax 1700/VMX17Y(C) 2009 Service Manual (P/N LIT-11616-22-64)

• Official Yamaha factory service manual for the 2009 VMX17Y(C), first edition, August 2008. Coverage includes 2S31 (USA) and 2S32 (California); document identity is P/N LIT-11616-22-64, Yamaha cover code 2S3-28197-10, in a 583-page PDF.
• Engine sections cover removal and installation, camshafts and timing chains, cylinder heads, valves, generator and starter clutch, hydraulic clutch, oil pump, crankcase, connecting rods and pistons, crankshaft and balancer, five-speed transmission, middle gear, and the related inspection and reassembly work.
• Fuel and electronic-control chapters detail YCC-T (Yamaha Chip Controlled Throttle), YCC-I (Yamaha Chip Controlled Intake), throttle-body synchronization and cleaning, injector and fuel-pressure testing, throttle and accelerator position-sensor adjustment, EXUP cable setup, and California-only canister components.
• Chassis procedures include wheel and ABS sensor-rotor work, static balancing, brake caliper and master-cylinder repair, ABS hydraulic-unit operation tests, fork disassembly, steering-head service, rear suspension and swingarm work, plus shaft-drive backlash and gear alignment.
• Diagnostic material provides ECU self-diagnosis, meter diagnostic mode, FI fault-code tables, sensor monitoring and actuator tests, ABS warning-light diagnosis, stored-code retrieval and deletion, circuit-specific troubleshooting, and final operational checks.
• Exploded views and job charts are backed by cable-routing drawings, FI and YCC system diagrams, ABS block and coupler-location charts, lubrication and cooling routing, system circuit diagrams, and a wide-format color wiring diagram.

Contents Overview

This reference material organizes Yamaha OEM technical data into a logical sequence for model identification, periodic service, repair, and dealer-level diagnosis. It is written for qualified technicians and experienced owners working on the 1,679 cc liquid-cooled, four-stroke DOHC V4. Coverage is limited to this 2009 configuration rather than later VMAX model years. The USA and California versions are separated where their equipment differs; the California build receives specific canister, purge-hose, throttle-body identification, cable-routing, and maintenance references.

Beyond the maintenance charts and routine adjustments, the engine chapter documents removal, internal disassembly, inspection, selection, and assembly for the top end and bottom end. Covered work includes cam timing, valve and guide service, cylinder and piston checks, bearing selection with identification codes and Plastigauge, crankcase angle-tightening sequences, connecting-rod bolt procedures, transmission-shaft inspection, and middle-gear backlash and alignment. The clutch section handles the clutch pack, master cylinder, and release cylinder, while the lubrication section covers the oil pump, strainers, pipes, nozzles, relief valve, and oil pan.

Chassis coverage combines normal repair work with model-specific procedures that are easy to miss in a general motorcycle book. Front and rear wheels are shown with ABS sensor-rotor maintenance and static-balance procedures. The brake chapters cover pads, discs, calipers, master cylinders, hose routing, system bleeding, and ABS hydraulic-unit tests. Separate sections handle the fork legs, steering head, rear shock and gas cylinder, suspension linkage, swingarm, final drive, and drive shaft. Cooling-system repair includes the main and sub radiators, oil cooler, thermostat, and water pump; fuel-system repair includes the tank, pump, rollover valve, air-filter case and intake funnels, throttle bodies, injectors, and air-induction system.

Diagnostics, Diagrams, and Specifications

The electrical section is organized by ignition, starting, charging, lighting, signaling, cooling-fan, fuel-injection, fuel-pump, ABS, and individual component tests. The built-in meter diagnostic mode can display sensor data and command ignition coils, injectors, the intake-funnel servo, EXUP servo, relays, and other actuators. FI tables link fault codes to probable causes, connector and wire checks, fail-safe behavior, and reinstatement methods. ABS coverage adds component and coupler charts, warning-light logic, ECU memory, fault-code diagnosis, code deletion, hydraulic-unit operation tests, and a final trial run.

The drawing set supports both fault tracing and assembly. Representative examples include the FI system layout and YCC-T/YCC-I system outline; the ABS block diagram and software-operation flow; the engine-oil lubrication chart with sectional routing drawings; cooling-system diagrams; the ABS coupler-location chart; and the complete VMX17Y(C) 2009 wiring diagram with connector views and color codes.

Specification chapters provide component-specific torque tables, lubrication points, fluid-capacity data, wear limits, clearances, runout limits, shim and bearing-selection data, electrical test values, and complete cable routing. The manual also identifies the factory tools used in those procedures, including the ABS test coupler adapter 90890-03149, vacuum gauge 90890-03094 / carburetor synchronizer YU-44456, fork seal driver 90890-01502 / YM-A0948, middle-gear backlash tool 90890-04080, and fuel-injector pressure adapter 90890-03210 / YU-03210.

The ABS ECU and hydraulic unit are serviced as a non-disassemblable united assembly, and magnetic pickup tools can damage the wheel-sensor rotors. During YCC-T throttle-body cleaning, forcing the valves or touching the throttle shaft can damage operation or disturb synchronization. Camshaft caps must stay in their marked locations and be tightened evenly, while connecting-rod bolts are treated as new, angle-tightened fasteners; errors can damage the camshaft and cylinder head or compromise the bottom end.

Fuel pressure, brake fluid, ABS hydraulic service, and major engine or chassis removal require proper support, electrical isolation, ventilation, and protective equipment. Follow the manual's warnings and use the specified tools before beginning diagnosis or repair.
