Engine Type:
4-Stroke, DOHC, 3-Cylinder
Bore X Stroke:
Approx. 80.0 mm x 66.2 mm (refer to manual for exact specifications)
Compression Ratio:
Refer to manual for precise ratio (typically around 9.5:1 to 10.5:1 for this era)
Horsepower:
Estimated 130-140 HP (depending on specific tune and model year, refer to manual for exact figures)
Torque:
Refer to manual for specific torque figures.
Fuel Delivery:
Fuel Injection (EFI)
Fuel Type:
Unleaded gasoline (minimum octane rating specified in manual)
Oil Change Interval:
Refer to manual, typically every 100-150 hours or annually.
Spark Plug Replacement:
Refer to manual, typically at seasonal intervals or specific hour marks.
Drive Belt Inspection:
Regular inspection recommended, replacement based on wear and condition as per manual.
Engine Oil Type:
Yamalube or equivalent 4-stroke engine oil meeting API SG or higher, viscosity grade specified in manual (e.g., 10W-40 or 20W-50).
Engine Oil Capacity:
Refer to manual (typically around 3.5 - 4.0 liters).
Coolant Type:
Yamaha Super Coolant or equivalent (50/50 mix of ethylene glycol and distilled water).
Brake Fluid Type:
DOT 3 or DOT 4 hydraulic brake fluid (refer to manual for specific recommendation).
Clutch Wear:
As with many CVTs, clutch components (weights, springs, bushings) may require periodic inspection and replacement due to wear, especially under heavy use.
Fuel Injector Clogging:
Can occur with poor fuel quality; regular use of fuel additives and clean fuel is recommended. Manual provides cleaning procedures.
Suspension Bushings:
Wear in suspension bushings can lead to looseness and premature component failure; inspection is part of periodic maintenance.
