Choose an economical motorbike
be taken into account when buying motorcycle Motorcycle indicators, such as the motorcycle and what kind of roads, the maximum speed, acceleration, weight, consumption and so on. Oil indicators have special requirements, on the other indicators should also be a friendship, so that both fuel efficient vehicles must be purchased a certain level of performance. So, what kind of motorcycle provincial mud?
1, 2-stroke and four-stroke motorcycle engine motorcycle woman motivation compared with the more economical four-stroke motorcycle. This is because there is the two-stroke engine and exhaust rinsing process after the end of the process there is always a moment when the sweep bar to start the same porosity and emissions, then inevitably fresh one short breath gas flow from the vent, thus increasing part of the fuel without burning to the loss and the fuel consumption would.

2, the smaller displacement engine the more fuel-efficient.

3, with a flute reed valve and rotary inlet valve by two-stroke engine as the intake valve with a piston engine economical manner. This is because the flute added membrane block and rotary valve in the gas phase angles, so that the opening to prevent more fully, and also that the phenomenon of spraying the gas down, especially on behalf of the velocity is more significant results, the majority the new bikes have introduced the two recording methods, such as Yamaha RZ125 reed valve with the flute, Suzuki A100 uses a rotary valve.

Spare parts are replaced
Used Motorcycles pistons and cylinders for a long time have large gaps, if not in time and honing cylinder piston, in order to reduce this gap, it is to create leaks rapidly rising consumption.
How to determine whether the behavior of the motorcycle cylinder boring then? When in the course of a large increase in discovered oil consumption, there is percussion-cylinder, check the cylinder, remove the engine block, cylinder hand touching the top half if there any obvious wear track edge, or the height of the cylinder to measure the form of cylinder position and the distance between the piston skirt more than 0.15 mm, then it must be boring cylinders and pistons new, can be boring, generally three times per cylinder, and then have to bear if a new cylinder block to be replaced.
Motorcycles for a long time to have used the different parts of the room too big, run up and will be a lot of additional energy use, so that the fuel consumption increases, then the need for major repairs. Usually two motorcycle-repair thousands of miles of 10 meters, three more than 5 million meters. Overhaul of the bike will not be updated immediately in order to ensure good fuel economy records.

In the maintenance of fuel-efficient
Must ensure good ignition motorcycle, spark plugs, the spark must be strong enough. General sparks should be white, or a further test transformer winding, platinum, capacitive disabilities.
Always clean the air filter to make it smooth. Now use the paper core motorcycle multi-type air filter every񏆠 km drive must be compressed air or blow pump filter used to make adequate combustion air in the cylinder body, to participate. The valves have leakage phenomenon.
If the valves or the intake and exhaust valve seat wear is to be repaired or replaced immediately. Repair or replacement must be leak test on the cylinder head upside-down when in gasoline, are five minutes there is no leakage. Piston ring gap can not be greater than 0.5 mm, or should be replaced.
Carburetor must be a good oil condition, type carburetor, throttle and seat between Ruoyin his make greater distance to the air cylinder can not make all the atomization of the fuel, the need for timely repair or replacement. Combustion air and fuel is only part of the air can provide a more complete combustion of fuel to the fuel consumption to achieve the purpose.
Turn the carburetor fuel supply arrangements, if there are three: First, reduce the float chamber of oil a suitable height, and secondly, necrosis of the small main jet direct measurements, which will be three main needle reduced in order to reduce the cross-sectional area of fuel passage. At the same time reduce the oil supply two motorcycles and a maximum speed acceleration, it should allow them to keep a fairly level, then the fuel consumption is the most reasonable.

What speed is more economical
1, the engine fuel consumption curve of the hook shape, medium-speed range in areas of low fuel consumption. Average speed generally refers weeks per minute between 3000-4000, when less than this speed, mixed-flow deteriorated discount on mixed uneven combustion fuel consumption has on the rise speed above this range, the largest engine in order to fully power the dark gas engine carburetor, fuel consumption also increased, according to this principle, as long as the speed control in the middle often tied to fuel-efficient speed range. Three motorcycle with two wheels of a motorcycle engine and the overall ratio is different, three-wheel motorcycle gear ratio between the 8-9, two motorcycles at 5-6 overall ratio between the three wheeled motorcycle that week in 3000-40Ǡ per minute speed, driving third walking speed of Ǵ-30 km / h, fourth gear for the 40 kmh top, two motorcycle-week in the corresponding 3000-4000 per minute speed, three speed Files 30-40 km per hour, fourth gear above 50 kilometers per hour ; above medium speed throttle position, so as to avoid the use of fuel efficient big choke should be more use of the center position of the throttle to make.
2nd Take full advantage of the inertia can be fuel-efficient motorcycle. A kind of time travel is not to use the inertia brake, you simply stop motorcycles, auto-stop after running some. There is such a situation is in the lane in front of the driver than the distance barrier, the early delay Bian gap taxi, car, before the barrier, decrease the speed, there may be emergency treatment, making the use of the system observed withdrawal of the method of the energy consumption ofmotors, so you can fuel.
g, in the long haul, it’s if you want fuel economy, you must use the bike in the speed when the master minimum fuel consumption. Usually two cycles if the minimum fuel consumption speed 70-80 km per hour, three motorcycles to 45-50 km per hour on wheels.
4, reasonably fuel-efficient tire pressure is an important factor, motorcycle tire pressure must be consistent with the description requirement. If the pressure is enough, the tire deformation to unnecessary consumption of energy-management lead to increased fuel consumption, so that every time, before driving, in particular long-distance running, it is best to use, such as tire pressure To test barometer.
It should be noted that some people think that driving is more economical use of taxi ways, this concept is wrong. Taxi drivers seem to be more economical, but increases the motorcycle must be before the sliding door to a higher speed, fuel consumption will be accelerated in this phase, the average is not necessarily more economical will, in the city where the taxi drivers are unsafe, because the film is not in production to participate, if the engine can only rely on brakes, it brakes less effective, very safe in an emergency.

In the process of economical cars
There are many ways to motorcycle fuel consumption, such as purchasing fuel-efficient cars, fuel-efficient maintenance of the measures taken and fuel-efficient driving style and used cars and other timely updates. How fuel-efficient driving, which is the key.

Start motorcycle and after a cold start the engine run a minute or so, the throttle handle to replace a fully open position. Some people like to smother a point of view, this combustible mixture into the cylinder too thick, resulting in increased fuel consumption and power down.Some people start off after not only not as economical, but also accelerate the wear of engine parts.

Initial application of low speed off. Do not step on the gas before the clutch until the clutch slowly semi in one-relaxed state, the clutch linkage, while a large throttle opening hit too slowly to the requirements of the engine speed and begin to get a smooth start motorcycle, or make the engine work is not continuous, a loose coupling of the flame, so that repeated several times, consumption much.

Control gear shift time to time. After starting motorcycle when the flat, smooth road to follow, it rapidly through a low-speed data exchange in a high gear. Do not use low-speed dash or a long ride. If the engine power was not sufficient to slow down gradually (eg, uphill), the original stall does not fit go further, they should quickly to the low level gear changes. Do not use high-quality hit hardest, the engine is too difficult, do not use the clutch linkage and the throttle half way to improve speed.

To maintain speed drive (that is, near the economic speed). The higher the speed, the greater the drag, fuel consumption increases. Lower speed, the lower the associated equipment, the smaller engine power utilization and hence the distance for the existence of the same increase in fuel consumption required. In addition, the inertia of moving full use of fuel-efficient: to make one is to stop some, if not only the use of motorcycle brake systems of inertia, making the oil after running a stop automatically. Another is to find the distance in front of more obstacles, obviating on the earlier slide delay, speed of the vehicle to the period before the barrier to reduce, it is possible contingency, so you avoid the use of motor deceleration method energy consumption.

Not speed up the throttle when accelerating increase end. As long as you reach the speed shall be so placed. Some people develop a habit to drive: the car under the H-2 air-oil, you get into the oil under H-2, or even replace the speakers with the room H-oil. This not only will gasoline consumption significantly, but acceleration increases the mechanical wear and engine noise.

Proper tire inflation pressure is an important factor in fuel-efficient driving, motorcycle tire pressure should be consistent with the description requirement. If insufficient air pressure, tires will be distorted and soak up the unnecessary energy consumption. Therefore, before every ride, especially long distance running before, better to check that tire pressure is normal.

As the transition to fuel-saving lies behind it? Let the following statements: Motor fuel consumption curve of the hook shape, medium-speed range, in areas of low fuel consumption.Average speed generally refers to 3000 between 4000 rpm and where less than mixed this speed, heavier flow reduction to mixed uneven combustion, increasing fuel consumption, speed above this range to the full play, give the engine maximum power, the engine carburetor gas darker, fuel consumption also increased, according to this principle, as long as the speed control in the middle often tied to fuel-efficient speed range.

Three-wheeled motorcycle with two motorcycle engine and the overall drive ratio is different wheeled, three wheeled motorcycle ratio of 8 ~ 9,ł motorcycles than the corresponding total transmission 5 to 6, 3-wheel motorcycle ~ 4000 3000 rpm speed , three-speed transmission 20 to 30 km per hour, Sidang over 40 km per hour, two motorcycle 3000 points corresponds to 4000 rpm speed, three-course speed of 30 to 40 km per hour, about 50 km Sidang per hour.These are medium speed throttle position, so as to avoid the use of fuel efficient big choke should be more use of the center position of the throttle to make.

Moving full advantage of the inertia can be fuel-efficient motorcycle. When about to stop, not only the use of motorcycle brake inertia, after running a stop automatically.
