V Boost Description:
Vacuum-controlled butterfly valves in intake manifold that open at higher RPMs to increase airflow and power.
Oil Type:
Yamaha recommends API SG or higher, SAE 20W-40 motorcycle oil (refer to manual for exact specification and capacity)
Oil Change Interval:
Typically every 3,000-5,000 km (1,800-3,000 miles) or 6 months, whichever comes first (refer to manual for precise recommendation).
Valve Adjustment Interval:
Recommended every 10,000-15,000 km (6,000-9,000 miles) or as per manual schedule.
Spark Plug Replacement:
Typically every 10,000-15,000 km (6,000-9,000 miles).
Brake Fluid:
DOT 3 or DOT 4 (refer to manual for exact specification and change interval).
Coolant:
