YZ450F Engine Reshaped intake ports The YZ450F’s innovative 5-valve cylinder head design is one of the most sophisticated in the category, and plays a vital role in enabling this high-tech MX bike maintain its well-documented superiority on the race track. For 2008 the combustion efficiency of this advanced cylinder head is further improved with the introduction of reshaped intake ports which enhance the bike’s low to mid-range performance.

In order to optimise the significant performance gains of the new intake port design, the latest YZ450F’s 5-valve cylinder head is equipped with new camshafts featuring reshaped Yamaha Motor Europe N.V. Page 6 of 33
profiles. The inlet valve timing has been adjusted, the overlap is modified and exhaust lift is revised to create an idealised balance of intake and exhaust operations for increased combustion efficiency and improved performance in the important low to mid-range zone. Reduced piston clearance The YZ450F powerplant is already one of the most advanced 4-stroke engine designs in the MX world, featuring cutting-edge technology which gives it a real advantage. Extensive use of lightweight materials has enabled Yamaha to create a light, compact and high-revving engine which produces a remarkably wide band of hard hitting power – and for 2008 our engineers have further reduced cylinder/piston tolerances of the 95mm diameter piston in order to enhance the overall package. These reductions may only be measurable in terms of microns, yet the differences are most definitely tangible, and include increased torque output, smoother running and quieter operation. New 94dB silencer Complying with the new FIM94dB(A) regulations is a new stainless steel silencer which maintains the machine’s strong low to mid-range power output, while reducing overall noise.

During more than 25 years as one of the world’s leading manufacturers of advanced motocross machinery Yamaha has consistently developed and produced exciting and innovative new engine technology. Now Yamaha are about to amaze the off-road world once again with what is surely the most important new powerplant to be produced since our liquid cooled YZ 2-strokes of the early 1980s. Extremely compact and remarkably light, the YZ400F’s 4-stroke powerplant incorporates some of the most sophisticated technology ever seen on a production motocross engine. Displacing 399cc, this 55hp high performance liquid cooled motor features bore and stroke dimensions of 92 x 60.1mm – a free-revving short stroke configuration which allows this ground-breaking motorcycle to produce a wider powerband than today’s 250cc 2-strokes. Short skirt piston runs in a ceramic composite plated cylinder which reduces frictional losses, thereby enhancing throttle response throughout the rpm range. To ensure overall dimensions are kept to a minimum this revolutionary new engine is fitted with an extremely light and compact 5-valve cylinder head. Running a 12.5:1 compression ratio and with a combustion chamber volume of 20.8 cc, this high efficiency 5-valve design runs with lightweight valves, springs and lifters for immediate throttle response and smooth high rpm operation. Feeding the three lightweight inlet valves is a 39mm Keihin flat-slide carburettor which breathes through a large capacity airbox. Special feature on the YZ400F’s intake side is an innovative air valve which is designed to ensure easy starting when the engine is warm. A tube connects the machine’s inlet manifold directly to the airbox, bypassing the FCR39 carburettor. By pulling the air valve’s choke-type knob, air is fed straight from the airbox into the engine for easier warm starting.

Shift timing indicator light This indicator light can be set to come on and go off at the desired engine speeds and is used to inform the rider when it is time to shift to the next higher gear. The electrical circuit of the indicator light can be checked by turning the key to “ON”. If the indicator light does not come on for a few seconds, then go off, have a Yamaha dealer check the electrical circuit. (See pages 3-7-3-10 for a detailed explanation of the function of this indicator light and on how to set it.) EAU04923* Coolant temperature warning light “” This warning light comes on when the engine overheats. When this occurs, stop the engine immediately and allow the engine to cool. The electrical circuit of the warning light can be checked by turning the key to “ON”. If the warning light does not come on for a few seconds, then go off, have a Yamaha dealer check the electrical cir- cuit. Multi-function display The multi-function display is equipped with the following: a speedometer (which shows the riding speed) an odometer (which shows the total distance traveled) two tripmeters (which show the distance traveled since they were last set to zero) a fuel reserve tripmeter (which shows the distance traveled since the fuel level warning light came on) a clock a self-diagnosis device a display brightness and shift timing indicator light control mode NOTE: Be sure to turn the key to “ON” before using the “SELECT” and “RESET” buttons. To switch the speedometer and odometer/tripmeter displays between kilometers and miles, press the “SELECT” button and “RESET” button together for at least two seconds. Odometer and tripmeter modes Pushing the “SELECT” button switches the display between the odometer mode “ODO” and the tripmeter modes “TRIP 1″ and “TRIP 2″ in the following order: ODO → TRIP 1 → TRIP 2 → ODO If the fuel level warning light comes on (see page 3-2), the odometer display will automatically change to the fuel reserve tripmeter mode “F-TRIP” and start counting the distance traveled from that point. In that case, pushing the “SELECT” button switches the display between the various tripmeter and odometer modes in the following order: F-TRIP → TRIP 1 → TRIP 2 → ODO → F-TRIP

Rear brake lever The rear brake lever is located on the left handlebar grip. To apply the rear brake, pull this lever toward the handlebar grip. EAU13182 Fuel tank cap To remove the fuel tank cap, turn it counterclockwise, and then pull it off. To install the fuel tank cap, insert it into the tank opening, and then turn it clock- wise. WARNING EWA11091 Make sure that the fuel tank cap is properly closed after filling fuel. Leaking fuel is a fire hazard. EAU13221 Fuel Make sure there is sufficient gasoline in the tank. WARNING EWA10881 Gasoline and gasoline vapors are extremely flammable. To avoid fires and explosions and to reduce the risk of injury when refueling, follow these instructions. 1. Before refueling, turn off the engine and be sure that no one is sitting on the vehicle. Never refuel while smoking, or while in the vicinity of sparks, open flames, or other sources of ignition such as the pilot lights of water heaters and clothes dryers. 2. Do not overfill the fuel tank. When refueling, be sure to insert the pump nozzle into the fuel tank filler hole. Stop filling when the fuel reaches the bottom of the filler tube. Because fuel expands when it heats up, heat from the engine or the sun can cause fuel to spill out of the fuel tank. Your Yamaha engine has been designed to use regular unleaded gasoline with a pump octane number [(R+M)/2] of 86 or higher, or a research octane number of 91 or higher. If knocking (or pinging) occurs, use a gasoline of a different brand or premium unleaded fuel. Use of unleaded fuel will extend spark plug life and reduce maintenance costs. Gasohol There are two types of gasohol: gasohol containing ethanol and that containing methanol. Gasohol containing ethanol can be used if the ethanol content does not exceed 10% (E10). Gasohol containing methanol is not recommended by Yamaha because it can cause damage to the fuel system or vehicle performance problems
