EAS30003 MODEL LABEL The model label “1” is affixed to the frame under the passenger seat. This information will be needed to order spare parts. In the conventional carburetor system, the air-fuel ratio of the mixture that is supplied to the combustion chamber is created by the volume of the intake air and the fuel that is metered by the jet used in the respective carburetor. The pressure regulator maintains the fuel pressure that is applied to the fuel injector at a certain level. Accordingly, when the energizing signal from the ECU energizes the fuel injector, the fuel passage opens, causing the fuel to be injected into the intake manifold only during the time the passage remain open. This degree of intake vol- ume control gives both improved low to mid-range power, as well as improved power in the higher rpm range. A white background and a black background can be selected for the background illumination, and the display also features automatic brightness adjustment activated by a sensor that measures ambient light conditions. The tachometer displays the over-8,000 rpm to redline range used most often in racing with a high degree of clarity and detail. This mode features high priority displays of lap number, lap times as well as a stopwatch function, all useful items for racing.http://www.caritas.nidzica24.pl/userfiles/dod-tec-4x-manual.xml

Each display also has a memory function that enables lap-by-lap time verification for quick post-race analysis. When the brake lever is squeezed, the rear brake force is controlled electronically according to the brake lever input (hydraulic pressure) and the rear brake force is adjusted depending on the bank angle during cornering. This causes a difference between the wheel speed and the chassis speed. Slip ratio is the value that shows the rate of wheel slippage and is defined by the following formula.The ABS also includes a highly developed self-diagnosis function. The ABS has been designed to op- erate as a conventional brake system if the ABS malfunctions. When the main switch is turned to “ON”, the ABS warning light comes on during the ABS self-diagnosis to check the electrical circuit of the light. During this test, a “clicking” noise can be heard from under the seat, and if the brake lever or brake pedal is even slightly operated, a vibration can be felt at the lever and pedal, but these do not indicate a malfunction. This icon shows the current ERS mode. (Refer to “YRC Setting” on page 1-37 and “ERS (YZF- R1M)” on page 1-39 to change the registered ERS mode or adjust ERS setting levels.) The ERS indicator will flash should the SCU need to be reset, but this does not indicate a.

A photo sensor equipped in the instrument panel detects lighting conditions and will automatically change the display be- tween its day and night settings. The photo sen- sor also controls a subtle automatic brightness adjustment function within both day and night modes to suit ambient light conditions.http://ceibsmobi.com/UploadFiles/dod-shelf-life-manual.xml Short push the wheel switch to confirm the setting and exit. 3.
