Since heat and deposits will cause any spark plug to slowly erode, the spark plug should be removed and checked in accordance with the periodic maintenance and lubrication chart. In addition, the condition of the spark plug can reveal the condition of the engine. Check the spark plug for electrode erosion and excessive carbon or other deposits, and replace it if necessary. Specified spark plug: NGK/BR10EG 1. Check that the porcelain insulator around the center electrode of the spark plug is a medium-to-light tan (the ideal color when the vehicle is ridden normally). NOTE: If the spark plug shows a distinctly different color, the engine could be operating improperly. Instead, have a Yamaha dealer check the vehicle. To install the spark plug 1. Measure the spark plug gap with a wire thickness gauge and, if necessary, adjust the gap to specification. Remove the spark plug as shown, with a spark plug wrench available at a Yamaha dealer. Spark plug gap: 0. 5­0. 6 mm (0. 020­0. 024 in) 6-8 PERIODIC MAINTENANCE AND MINOR REPAIR 2. Clean the surface of the spark plug gasket and its mating surface, and then wipe off any grime from the spark plug threads. Install the spark plug with the spark plug wrench, and then tighten it to the specified torque. Tightening torque: Spark plug: 20 Nm (2. 0 m·kgf, 14 ft·lbf) EAU41441 Transmission oil The transmission oil must be checked for oil leakage before each ride. If any leakage is found, have a Yamaha dealer check and repair the motorcycle. In addition, the transmission oil must be changed at the intervals specified in the periodic maintenance and lubrication chart. Start the engine, warm it up for several minutes, and then turn it off. Place the motorcycle on a level surface and hold it in an upright position. Remove the oil filler cap and drain bolt to drain the oil from the transmission. 1. Transmission oil drain bolt 6 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. Install the transmission oil drain bolt, and then tighten it to the specified torque. Tightening torque: Transmission oil drain bolt: 10 Nm (1. 0 m·kgf, 7. 2 ft·lbf) 6. Add the specified amount of the recommended transmission oil, and then install and tighten the oil filler cap. Recommended transmission oil: See page 8-1. [. . . ] Perform the following steps to protect the cylinder, piston rings, etc. Install the spark plug cap onto the spark plug, and then place the spark plug on the cylinder head so that the electrodes are grounded. Remove the spark plug cap from the spark plug, and then install the spark plug and the spark plug cap. MOTORCYCLE CARE AND STORAGE EWA10950 WARNING To prevent damage or injury from sparking, make sure to ground the spark plug electrodes while turning the engine over. Lubricate all control cables and the pivoting points of all levers and pedals. [. . . ]
