Visual Aids:
Includes step-by-step instructions with pictures and wiring diagrams.
Engine Type:
Likely a 700cc liquid-cooled, 2-stroke, 2-cylinder engine (common for this era Yamaha models). Specific engine code/variant (e.g., from the MM700 designation) would require deeper internal manual data.
Estimated Horsepower:
Typically in the range of 90-110 HP for this class of 700cc 2-stroke Yamaha engines from this period, but specific figures would be detailed within the manual.
Estimated Torque:
Corresponding torque figures would be provided in the manual, crucial for clutch tuning and performance analysis.
Fuel Delivery:
Carbureted (likely Mikuni or similar twin carburetors). Specific models may have dual carbs.
Recommended Fuel:
Typically requires premium unleaded gasoline (91 octane or higher) and proper 2-stroke oil mixture for lubrication, as specified by Yamaha.
Oil System:
Autolube (oil injection system) or premix, depending on specific model variant. Manual will detail the correct system and oil types.
Cylinder Arrangement:
Inline Twin (most probable for 700cc models of this era).
Cooling Method:
Liquid-cooled.
Transmission Type:
CVT (Continuously Variable Transmission) with a centrifugal clutch system.
Gear Selection:
Forward, Neutral, Reverse (if equipped). Typically operated by a gear selector lever.
Clutch System:
Includes detailed maintenance and adjustment procedures for both the primary (drive) clutch and secondary (driven) clutch.
Drive Belt Maintenance:
Covers inspection, tensioning, and replacement of the drive belt.
Chaincase Oil:
Specific SAE viscosity and capacity for the chaincase oil will be detailed in the manual. Typically a gear oil like SAE 80W-90.
Oil Change Interval:
Typically every 50-100 hours of operation or annually, with specific recommendations in the manual. Chaincase oil change is typically after initial break-in and then annually or every 100-200 hours.
Spark Plug Replacement:
Recommended replacement every 100-200 hours or as needed based on inspection. Manual will provide gap specifications.
Drive Belt Inspection:
Frequent inspection recommended, especially before extended rides. Replacement interval varies significantly based on usage and belt condition, typically 1,000-2,000 miles or as indicated by wear.
Engine Oil Type:
Yamaha's recommended 2-stroke oil (e.g., Yamalube 2M) or an equivalent API-TC or JASO FD certified 2-stroke oil for oil injection systems. Manual will specify exact type and grade.
Coolant Type:
Typically a 50/50 mixture of permanent antifreeze and distilled water. Manual will specify the exact type (e.g., ethylene glycol-based) and color.
Common Wear Items:
Drive belts, clutch weights/rollers, carbides on skis, track lugs, and shock seals are common wear items. Manual will guide on their inspection and replacement.
Carburetor Issues:
Clogged jets, incorrect float height, or worn diaphragms can lead to poor running conditions. Manual covers thorough cleaning and adjustment.
Manufacturer:
Yamaha Motor Corporation, known for a long history of innovation in powersports and motorcycles.
Series Context:
The VX, SX, MM, and VT series likely represent various chassis, suspension, or feature packages built around the common 700cc engine platform, common in Yamaha's performance and touring snowmobiles of the early 2000s.
Manufacturing Location:
Yamaha snowmobiles are typically manufactured in their specialized facilities, often in North America.
