[. . . ] EAU00002 INTRODUCTION Congratulations on your purchase of the Yamaha Road StarTM/Road StarTM SilveradoTM. This model is the result of Yamaha's vast experience in the production of fine sporting, touring, and pacesetting racing machines. It represents the high degree of craftsmanship and reliability that have made Yamaha a leader in these fields. This manual will give you an understanding of the operation, inspection, and basic maintenance of this motorcycle. [. . . ] Do not attempt to diagnose such problems yourself. Instead, have a Yamaha dealer check the motorcycle. If a spark plug shows signs of electrode erosion and excessive carbon or other deposits, it should be replaced. Specified spark plug: DPR7EA-9/NGK or X22EPR-U9/DENSO Before installing a spark plug, the spark plug gap should be measured with a wire thickness gauge and, if necessary, adjusted to specification. Spark plug gap: 0. 03­0. 04 in (0. 8­0. 9 mm) 6-8 Clean the surface of the spark plug gasket and its mating surface, and then wipe off any grime from the spark plug threads. Tightening torque: Spark plug: 12. 5 ft·lb (1. 75 m·kgf, 17. 5 Nm) 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. @ @ a. Spark plug gap EAU01639 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. 6 PERIODIC MAINTENANCE AND MINOR REPAIR ECA00021 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. @ @ 1. Engine oil filler cap EAU00499 EAU04212* Canister (for California only) This model is equipped with a canister to prevent the discharging of fuel vapor into the atmosphere. Before operating this motorcycle, make sure to check the following: Check each hose connection. Check each hose and canister for cracks or damage. Make sure that the canister breather is not blocked, and if necessary, clean it. Engine oil and oil filter cartridge The engine oil level should be checked before each ride. In addition, the oil must be changed and the oil filter cartridge replaced at the intervals specified in the periodic maintenance and lubrication chart. Place the motorcycle on a level surface and hold it in an upright position. 6 6-9 PERIODIC MAINTENANCE AND MINOR REPAIR NOTE: Make sure that the motorcycle is positioned straight up when checking the oil level. A slight tilt to the side can result in a false reading. _ _ NOTE: When adding oil, be careful not to overfill the engine; the oil level rises faster starting from the half level portion on the dipstick. _ _ 2. (See page 3-11 for rider seat removal and installation procedures. ) 3. Start the engine, warm it up until the engine oil has reached a normal temperature of 140 °F (60 °C), let it continue to idle for ten seconds, and then turn the engine off. NOTE: To achieve the proper engine oil temperature for an accurate oil level reading, the engine must have first completely cooled down, and then warmed up again for several minutes to normal operating temperature. _ _ 1.
