Book Excerpt: 1987-2006 Yamaha Banshee YFZ350 Repair Manual FUEL AND EXHAUST SYSTEMS

The fuel system consists of the fuel tank, fuel shutoff valve, fuel lines, 2 carburetors and air filter. The engine receives its lubrication from a gasoline and oil mixture (pre-mix). The engine is not equipped with an oil injection system. Refer to Chapter Three for fuel/oil mixture ratios. The exhaust system consists of 2 expansion chambers and 2 silencers. This chapter includes service procedures for all parts of the fuel system and exhaust system. Air filter service is covered in Chapter Three. Carburetor specifications are covered in Table 1. Table 1-3 are at the end of the chapter.
CARBURETOR OPERATION For proper operation, a gasoline engine must be supplied with fuel and air mixed in proper proportions by weight. A mixture in which there is an excess of fuel is said to be rich. A lean mixture is one which contains insufficient fuel. A properly adjusted carburetor supplies the proper mixture to the engine under all operating conditions. The carburetor consists of several major systems. A float and float valve mechanism maintain a constant fuel in the float bowl. The pilot system supplies fuel at low speeds. The main fuel system supplies fuel at medium and high speeds. Finally, a starter (choke) system supplies a rich mixture needed to start a cold engine.

FRONT SUSPENSION AND STEERING

FRONT SUSPENSION Figure 27 (1987) and Figure 28 (1988-on) show the front suspension system. The control arms are bolted to mounting brackets welded to the frame. Ball joints connect both control arms to the steering knuckle. On all models, the ball joints are in integral part of the control arms and cannot be replaced separately. Steering is controlled by tie rods connected to the steering shaft and steering knuckle.
