PRE-OPERATION CHECKS
4The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or
loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual
inspection, to check the following points before each ride.
ITEM CHECKS PAGE
• Check fuel level in fuel tank.
Fuel• Refuel if necessary.3-6
• Check fuel line for leakage.
• Check oil level in oil tank.
Two-stroke engine oil• If necessary, add recommended oil to specified level. 3-7
• Check vehicle for oil leakage.
Final transmission oil• Check oil level and vehicle for oil leakage. 6-6
• Check operation.
• If soft or spongy, have Yamaha dealer bleed hydraulic system.
Front brake• Check fluid level in reservoir. 3-4, 6-11
• If necessary, add recommended brake fluid to specified level.
• Check hydraulic system for leakage.
• Check operation.
Rear brake• Check lever free play. 3-5, 6-11
• Adjust if necessary.
• Make sure that operation is smooth.
Throttle grip• Check cable free play.
