Leakage fault performance for two phenomena:

1 quick oil spills. Fast overflow pipe leakage phenomenon, sometimes also fast on balance pipe leak, causing the fuel into the engine combustion chamber, cylinder vehicles flooded, will not start. Cause more for: (a) a larger dirt stuck float chamber; (2) float spill damage; (3) on the float float dysfunctional pins. The solution is: clean float electric motorcycle motor needle and into the oil pipeline, the float can be replaced if damaged, can also be thrown out after the float in gasoline knot with a soldering iron. 2, slow permeability. Phenomenon for several hours after a motorcycle parked a few drop of the overflow pipe to the frequency of the slow drip. Failure to float needle or float needle seat is damaged, resulting in Mifengbuyan. The solution is: replace qualified float needle and needle seat assembly, for non-replaceable tight inlaid with casting type float needle seat, only replace the rubber head float needle. Replace the float needle still can not rule out the failure, you have to repair the float needle seat repair device. Repair is available 42 # steel rod production, the lathe is slightly thinner motorcycle engine size than the float needle into the hole seat, the top of the conical taper should be less than the original float needle taper. After completion of the processing must be polished with a cloth top, the top of the repair device into the float needle seat, with a lower number of wooden hammer tapping, then refitted float and float needle, insert tubing, open the oil switch, the carburetor upside down , after more than 10 minutes to see the needle seat with oil leaking, repair is normal. Repair generally make jh70 type, wh125 type two can repair can be reused.

A brief history of motorcycles

Since 1885 the German carrier Daimler invention manufactured the world's first car with a gasoline engine-powered motorcycles, motorcycle development has gone through 100 years of vicissitudes. The original motorcycle, existing in the real shape of the Museum of Science and Technology in Munich, Germany, is a German Daimler on August 29, 1885 patented invention of the world's first motorcycle priority. Limited to 100 years ago, when the gasoline engine is still in the low-naive status, when the vehicle is still for the carriage technology manufacturing stage, the original motorcycles electric motorcycle motor and modern motorcycles are very different in appearance, structure and performance. Mi motorcycle original frame is made of wood. Judging from wood, a carpenter from the processing. The wheel is made of wood. The outer layer covered with a metal wheel. The lower frame is? A square wooden frame on which the engine is placed on both sides of each wooden frame? Small supporting wheels, whose role is to prevent the dumping stationary. As such. This car is actually a four landing. Fan-cooled single-cylinder engine, the output power by two belts and gear reduction drive, driving the rear wheels forward. Made saddle seat, wrapped in a layer of leather. Its working volume of the engine cylinder 264mL, maximum power 0.37kW (7OOr / min), only one fifth of modern motorcycle simple. Speed ??of 12km, not much faster than motorcycle engine types walking. Ding did not spring from other cushioning device, this car was known as the "shock of bone car", it is conceivable. In the 19th century stone street driving, simply worse than execution. Although the original motorcycle is so simple, but since a motorcycle to constant change, continuous improvement, only 100 years the descendants of hundreds of millions of units of modern motorcycle.
