Yamaha XT350M / XT350MC Owner's Manual (P/N LIT-11626-13-18)

• Covers the Yamaha XT350M and XT350MC in a 99-page PDF owner’s manual, P/N LIT-11626-13-18, first edition July 1999.
• Engine lubrication procedures include oil and filter service and the post-change oil-pressure check, alongside air-filter cleaning and oiling and exhaust spark-arrester cleaning.
• Clutch free-play and drive-chain adjustments are explained, with wheel-alignment details and lubrication guidance for the sealed chain, control cables, and throttle grip.
• Front disc and rear drum brake coverage includes lever and pedal adjustments, pad and shoe wear checks, and front and rear wheel removal and installation.
• Rear-shock spring preload and damping-force adjustments are illustrated, with the adjustment ranges and standard settings identified.
• Battery care, fuse and bulb replacement, and sidestand switch checks cover routine electrical work. A troubleshooting chart addresses starting faults.

Operating Procedures and Maintenance

The maintenance and minor repair sections are suited to owners familiar with motorcycle service and equipped with the owner’s tool kit plus additional tools such as a torque wrench.

The manual provides detailed pre-operation inspection checklists, cold- and warm-engine starting guidance, and instrument function descriptions. Fuel-cock and choke operation, kick-starting, shifting, and engine break-in are also covered.

The Periodic Maintenance Chart for Emission Control System and General Maintenance and Lubrication Chart organize service by mileage and elapsed time. Asterisks identify jobs requiring special tools, data, and technical skills. Separate inspection coverage addresses front-fork operation, steering play, wheel bearings, and tire and spoke condition.

California-specific coverage includes evaporative-canister and hose inspections. The Emission Hose Routing diagram identifies connections between the fuel tank, carburetor, and canister, while the canister illustration labels the vent hose and overflow pipe.

The oil-service cautions explain the risk of engine seizure when oil fails to circulate after a change. Battery illustrations identify the breather hose; accompanying warnings explain how incorrect routing can discharge electrolyte onto the frame and cause structural damage.

Handling fuel and electrical systems on vintage motorcycles carries inherent risks. Reviewing the manufacturer's safety and handling warnings prior to any maintenance is highly recommended to prevent personal injury or equipment damage.

Troubleshooting and Repair Limits

The Sidestand Switch Operation Check chart covers the ignition cut-off function. The Troubleshooting Chart organizes basic fuel, compression, and ignition checks for poor starting or loss of power, with referral points for problems requiring further repair.

The distinction between a scheduled task and an included adjustment procedure matters here. Carburetor adjustment, valve-clearance adjustment, and decompression-cable adjustment are discussed, but the actual adjustment work is referred to Yamaha service personnel. The manual also directs owners to dealer service for brake bleeding, brake-fluid replacement, and internal shock-absorber work.

For internal engine or transmission repair, a separate workshop manual is needed. This owner’s manual does not contain overhaul procedures or a full electrical wiring diagram.

Specification Highlights

The 346 cc, air-cooled DOHC single-cylinder engine pairs with a constant-mesh 6-speed transmission and wet multi-disc clutch. The specifications identify the TEIKEI Y24PV carburetor, CDI ignition, and magneto charging system.

Reference data cover lubricant selection, spark-plug types and gaps, brake wear limits, and load-dependent tire pressures. Electrical specifications list battery types, charging-system output, bulb ratings, and fuse capacity.

Oil quantities distinguish a routine change, filter replacement, and total fill. Component-specific tightening torques accompany the relevant service procedures, including spark-plug installation, oil-filter service, and wheel installation.
