  IDENTIFICATION EAS20130 IDENTIFICATION EAS20140 VEHICLE IDENTIFICATION NUMBER The vehicle identification number “1” is stamped into the right side of the steering head pipe. EAS20150 MODEL LABEL The model label “1” is affixed to the seat rail reinforcement under the passenger seat. This information will be needed to order spare parts.

• Page 11: Outline Of The Fi System

  FEATURES EAS20170 FEATURES EAS30340 OUTLINE OF THE FI SYSTEM The main function of a fuel supply system is to provide fuel to the combustion chamber at the opti- mum air-fuel ratio in accordance with the engine operating conditions and the atmospheric tempera- ture.

• Page 12: Fi System

  FEATURES EAS14B1017 FI SYSTEM The fuel pump delivers fuel to the fuel injector via the fuel filter. The pressure regulator maintains the fuel pressure that is applied to the fuel injector at 324 kPa (3.24 kgf/cm², 47.0 psi). Accordingly, when the energizing signal from the ECU energizes the fuel injector, the fuel passage opens, caus- ing the fuel to be injected into the intake manifold only during the time the passage remains open.

  YCC-T (Yamaha Chip Controlled Throttle) YCC-I (Yamaha Chip Controlled Intake) Mechanism characteristics Yamaha developed the YCC-T and YCC-I system employing the most advanced electronic control technologies. Electronic control throttle systems have been used on automobiles, but Yamaha has developed a faster, more compact system specifically for the needs of a sports motorcycle. The Yamaha-developed system has a high-speed calculating capacity that produces computations of running conditions every 1/1000th of a second.
• Page 14
  FEATURES Aims and advantages of using YCC-I system • Improved power band By using a dual intake funnel system, YCC-I optimizes the effectiveness of the fuel injection sys- tem to deliver an incredibly precise air/fuel mixture to the combustion chamber. This degree of intake volume control gives both improved low to mid-range power, as well as improved power in the higher rpm range.

  EAS20200 REPLACEMENT PARTS Use only genuine Yamaha parts for all replace- ments. Use oil and grease recommended by Yamaha for all lubrication jobs. Other brands may be similar in function and appearance, but inferior in quality.

• Page 26: Bearings And Oil Seals

  IMPORTANT INFORMATION EAS20230 BEARINGS AND OIL SEALS Install bearings and oil seals so that the manu- facturer’s marks or numbers are visible. When installing oil seals “1”, lubricate the oil seal lips with a light coat of lithium-soap-based grease. Oil bearings liberally when installing, if appro- priate.
