How to maintain the scooter of 125?
Second, the driving situation is that when you want to stop, you only use the inertia of the motorcycle without braking, and stop automatically after driving for a period of time.
Third, in long-distance driving, if you want to save fuel, you must master the speed of the motorcycle you use at the lowest fuel consumption. Generally speaking, the minimum fuel consumption speed of two-wheeled motorcycles is 70-80 km/h,
4. Reasonable tire pressure is an important factor for fuel-efficient driving. Motorcycle tire pressure must meet the requirements of the manual. If the air pressure is insufficient, the tire will consume unnecessary energy and increase fuel consumption. Therefore, it is best to check the tire pressure with a barometer before driving, especially before driving for a long distance.
Verb (abbreviation of verb) What fuel-saving measures can be taken in motorcycle maintenance? We must ensure that the motorcycle has good ignition performance, and the spark plug must have enough spark. Generally, the spark should be white, or further check whether there is any problem with the high-voltage coil, platinum and capacitor.
Six, the air filter should be cleaned frequently and kept open. At present, motorcycles mostly use paper core air filters. Every 4000 kilometers, it is necessary to use compressed air or air pump to blow off the dust on the filter element. It is forbidden to clean the filter element with gasoline to prevent the filter element from being polluted by oil. Only a clean filter element can make enough air enter the cylinder to participate in combustion. Air leakage may occur in the intake and exhaust valves. If the intake and exhaust valve or the intake and exhaust valve seat is worn, it should be repaired or replaced in time. After repair or replacement, air leakage must be checked. When checking, turn the cylinder head upside down and pour gasoline, and it will not leak within five minutes. Piston ring opening clearance should not be greater than 0.5 mm, otherwise it should be replaced in time. The carburetor should be in a good oil supply state. If the gap between the throttle valve and carburetor seat becomes larger due to wear, all the air entering the cylinder block can not be used to atomize the fuel, so it must be repaired or replaced in time. When air and fuel are completely burned, the weight ratio of air and fuel (called air-fuel ratio) is 18: 1. When the air-fuel ratio of a good carburetor is 22: 1, the fuel supply should be adjusted to 22: 1. Only by providing more air can the fuel burn completely and achieve the purpose of saving fuel. Three measures can be taken to adjust the fuel supply of carburetor: one is to appropriately reduce the oil level height of the float chamber, the other is to reduce the linear size of the main metering hole, and the third is to reduce the position of the main oil needle to reduce the cross-sectional area of fuel passing through. When reducing the fuel supply, we should consider the acceleration and maximum speed of the motorcycle to make it have a considerable level. Fuel consumption is the most reasonable at this time.
