[. . . ] Panel B 6-9 PERIODIC MAINTENANCE AND MINOR REPAIR EAU33990 EAU19651 Panels B and D To remove one of the panels 1. Remove the screw, and then remove the panel as shown. Checking the spark plugs The spark plugs are important engine components, which should be checked periodically, preferably by a Yamaha dealer. Since heat and deposits will cause any spark plug to slowly erode, they should be removed and checked in accordance with the periodic maintenance and lubrication chart. In addition, the condition of the spark plugs can reveal the condition of the engine. The porcelain insulator around the center electrode of each spark plug should be a medium-to-light tan (the ideal color when the vehicle is ridden normally), and all spark plugs installed in the engine should have the same color. If any spark plug shows a distinctly different color, the engine could be defective. Do not attempt to diagnose such problems yourself. Instead, have a Yamaha dealer check the vehicle. If a spark plug shows signs of electrode erosion and excessive carbon or other deposits, it should be replaced. Specified spark plug: NGK/CR9EK 6-10 2. Place the panel in its original position, and then install the screw. PERIODIC MAINTENANCE AND MINOR REPAIR Before installing a spark plug, the spark plug gap should be measured with a wire thickness gauge and, if necessary, adjusted to specification. EAU19681 NOTE: If a torque wrench is not available when installing a spark plug, a good estimate of the correct torque is 1/4­1/2 turn past finger tight. However, the spark plug should be tightened to the specified torque as soon as possible. ECA10840 Canister (for California only) CAUTION: Do not use any tools to remove or install the spark plug cap, otherwise the ignition coil coupler may get damaged. The spark plug cap may be difficult to remove because the rubber seal on the end of the cap fits tightly. To remove the spark plug cap, simply twist it back and forth while pulling it out; to install it, twist it back and forth while pushing it in. This model is equipped with a canister to prevent the discharging of fuel vapor into the atmosphere. Before operating this vehicle, make sure to check the following: G Check each hose connection.
