Since heat and deposits will cause any spark plug to slowly erode, the spark plugs 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. Remove the spark plug as shown, with the spark plug wrench included in the owner's tool kit. Check that the porcelain insulator around the center electrode on each spark plug is a medium-tolight tan (the ideal color when the motorcycle is ridden normally). Check that all spark plugs installed in the engine have the same color. 6-9 PERIODIC MAINTENANCE AND MINOR REPAIR NOTE: 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 motorcycle. @ @ Tightening torque: Spark plug: 18 Nm (1. 8 m·kgf, 13 ft·lbf) 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. @ @ 3.
