|
Spark Plug Replacement:
|
Every 100 hours or annually. Inspect and clean at 50-hour intervals.
|
Valve Clearance Check:
|
Every 100 hours or annually.
|
Fluid Specifications
|
Coolant Type:
|
High-quality, permanent type coolant (50/50 mixture of ethylene glycol and deionized water). Check manual for specific Yamaha coolant recommendation.
