Engine Type:
Four-stroke, DOHC, 5-valve per cylinder, liquid-cooled inline-triple (Note: Manual mentions 'engine assembly' broadly; Apex models typically featured an inline-triple, while the Attak could have a different configuration. The provided text also hints at a 4-cylinder in the 'RX10' context, but 'RX10' historically refers to the Genesis 1000cc triple. Clarification needed if the manual covers multiple engine types within this chassis code.)
Engine Displacement:
Approximately 998cc (for the Genesis 1000 triple)
Horsepower:
Estimated 130-150 HP (varies by specific model and tuning)
Torque:
Not explicitly specified in product info, but known for strong mid-range torque.
Fuel Delivery:
Fuel Injection (EFI) or Carbureted (depending on specific model variant; manual covers both Carburetion and EFI)
Fuel Type:
Unleaded gasoline (minimum 87 octane recommended)
Cylinder Head Design:
DOHC, 5-valve per cylinder configuration, indicating high performance and efficient combustion.
Engine Oil Change:
Typically every 2,000-3,000 miles or annually, refer to specific manual section for exact interval and capacity.
Spark Plug Replacement:
Recommended at specific mileage intervals or based on condition checks, detailed in manual.
V-Belt Inspection:
Regular inspection for wear and damage, replacement as needed based on mileage or condition.
Valve Adjustment Interval:
Intervals for valve clearance adjustment are specified, crucial for maintaining engine performance and longevity.
Clutch Inspection:
Clutch components, including sheave offset and drive belt engagement speed, are subject to periodic checks and adjustments.
Engine Oil Type:
Yamalube 4-stroke oil (e.g., Yamalube 4W, 10W-40 or 20W-50 depending on temperature), refer to manual for precise specification.
Coolant Type:
Yamaha Supercoolant (50/50 mix of antifreeze and distilled water), or equivalent ethylene glycol-based coolant.
Brake Fluid Type:
DOT 4 hydraulic brake fluid.
Drive Belt Wear:
Drive belts can wear prematurely if subjected to excessive heat, improper alignment, or overloading. Regular inspection is crucial.
Suspension Bushings:
Bushings in suspension components can wear over time, leading to play and affecting handling. Manual covers inspection and replacement.
Carburetor Icing:
In very cold, humid conditions, carburetors can be susceptible to icing, impacting performance. Manual covers carburetor tuning and maintenance.
