Horsepower Estimated:
Approximately 35-45 HP (Horsepower), depending on specific tuning and model year variations.
Torque Estimated:
Estimated torque figures are not readily available without the specific manual, but would be in line with a 337cc two-stroke of the era.
Carburetion:
Single Mikuni carburetor (typical for this engine size and era), specific model number would be detailed in the manual.
Fuel Type:
Regular Unleaded Gasoline
Oil Mixture:
Pre-mix (typically 40:1 ratio of gasoline to high-quality 2-stroke oil), or oil injection system if equipped (check specific model details).
Transmission Type:
Automatic continuously variable transmission (CVT) clutch system (primary and secondary clutches).
Gear Selection:
Forward, Neutral, Reverse (if equipped, typically achieved via a gearbox in conjunction with the CVT).
Clutch System:
Utilizes a mechanical CVT system for automatic gear ratio changes based on engine RPM and load, optimizing power delivery.
Overall Length Estimated:
Approximately 90-100 inches (228-254 cm), typical for this class of snowmobile.
Overall Width Estimated:
Approximately 35-40 inches (89-102 cm).
Track Width Estimated:
Typically around 15 inches (38 cm) for the drive track.
Dry Weight Estimated:
Approximately 400-450 lbs (181-204 kg), though exact figures vary by year and specific options.
Safety Certifications:
Snowmobiles of this era did not undergo standardized crash ratings like automobiles. Safety was primarily based on design features and adherence to manufacturer guidelines.
Braking System:
Hydraulic disc brake (most common for this era) or mechanical drum brake, providing stopping power.
Kill Switch:
Emergency engine shut-off cord attached to the rider's apparel.
Lighting System:
Headlight, taillight, and brake light for visibility and signaling.
Track And Suspension:
Designed to provide stability and control on snow-covered terrain.
Dashboard Features:
Basic instrumentation including speedometer, odometer, engine temperature light (if applicable), and warning lights.
Assistance Systems:
None in the modern sense. Relies on rider skill and vehicle design for safe operation.
Connectivity Options:
No digital connectivity features.
Oil Change:
Regular checks recommended. Gear case oil change typically every 100-200 hours or annually. Refer to manual for precise intervals.
Spark Plugs:
Inspect and clean/gap at regular intervals, typically every 1,000-2,000 miles or annually. Replacement as needed.
Track Tension:
Check and adjust before each riding season and periodically during use.
Lubrication:
Grease points (suspension, steering) as per manual recommendations, typically before each season or as needed.
Gearcase Oil:
Yamaha's recommended gear oil or equivalent API GL-4 80W-90 hypoid gear oil.
Coolant Type:
Fan-cooled engine, no coolant required. Primary cooling is air circulation.
Brake Fluid:
DOT 3 or DOT 4 hydraulic brake fluid (if hydraulic brake system is equipped). Manual will specify exact type.
Clutch Wear:
CVT clutches (primary and secondary) are wear items and can require servicing, belt replacement, or recalibration over time.
Carburetor Issues:
Carburetors can become gummed up with stale fuel, leading to starting problems or poor running. Regular cleaning and tuning are essential.
Suspension Bushings:
Rubber bushings in the suspension can degrade over time, leading to looseness and poor handling. Replacement as needed.
Track Sprocket Wear:
Drive track sprockets can wear, especially with improper track tension, affecting performance and track life.
