Motorcycle malformation Judged By Color Of Exhaust
Motorcycle enrich our life, create it speedily and easily and expand our space. If your motorcycle release colored exhaust similar to government upon a flat road, it might have been under supreme illness. But you don’t habit to be panic, end the motorcycle and watch the color of the exhaust. If the exhaust is shimmering or even there is dark smoke, after that there is something wrong once the engine and you obsession to figure out the explanation and repair it.
Motorcycle enrich our life, make it quickly and easily and spread our space. But if you didn’t maintain the motorcycle well, it will as well as bring the p.s. endless make miserable and unnecessary economic losses. If your motorcycle freedom colored exhaust afterward paperwork on a flat road, it might have been under loud illness. But you don’t need to be panic, stop the motorcycle and watch the color of the exhaust. If exhaust is bland or slightly white, this suggests that your motorcycle is absolutely healthy. If the exhaust is black, blue or wealthy white, after that there is most likely some misery subsequent to the motorcycle. If the exhaust is vivid or even there is dark smoke, then there is something wrong when the engine and you compulsion to figure out the defense and repair it.
The black exhaust
Black seems to be a sad color. The explanation should be rich mixture. That is to say, the amalgamation of gas in cylinder component is more than the usual level. The incomplete combustion gas in the combustion chamber cause the carbon particle exhausted next the waste gas.
Failure is likely to arrive from the as soon as reason:
- Air filter is blocked fittingly there is not satisfactory freshen input.
- There is some difficulty later than motorcycle sprocket, bearing in mind idling expose inlet congestion, next the let breathe input is not enough.
- The oil level of float chamber is too high, some gasoline go directly into the cylinder without atomization, which will cause incomplete combustion.
- Main orifice wearout seriously and then the fuel injection from primary nozzle increases, which will cause incomplete combustion.
- Heating automatic valve is in start outlook and the enrich valve can’t be closed automatically, which will caused a rich mixture.
- Carbon enlargement in muffler, exhaust jam, waste gas stay in cylinder, which will caused incomplete combustion and later black smoke.
If the above failure is not eliminated promptly, that will guide to carbon accrual at ventilate valve, influnce the sealing of the combustion chamber, stop the engine facility and low the speed. You should end the motorcylce shortly and definite the trouble.
Then you can follow the steps below:
- Check whether the freshen cleaner is blocked or not.
- If the filter element is made of paper, greater than before to fine-tune the filter element.
- If the filter element is made of foamed plastic, it should be put in kerosene or incombustible detergent for cleaning, subsequently dryed, and coated once a small amount of lubricating oil. make laugh note that don’t put too much, on the other hand it will abbreviate the air input. And finally put the element inside the cleaner.
- Confirm that there is nothing incorrect in the manner of the let breathe cleaner. then check the 50cc carburetor. For plunger type carburetor, use compressed expose to blow throuhg every the holes and tube suitably as to check if the approach of the main oil needle is right or not.
- For those motorcyle as soon as vacuum diaphragm type carburetor, you craving to check begin heating automatic valve. Firstly, put the orange wires of start heating valve to anode of the battery and green wire to cathode of the battery. Then, practically five minutes later, be close to polyethylene pipe to fuel incremental loop and blow it subsequent to your mouth, if the loop is full closed, there will be no ventilation; If it can easily ventilated, which indicate the automatic valve can’t near the loop, after that you compulsion to regulate the begin heating automatic valve.
The blue exhaust
Blue is a color of melancholy. If the exhaust is blue, you won’t be happy too, which indicates that the engine oil is burning. This is mainly caused by the when reasons:
- There is a large clearance amid cylinder and piston or valve and valve guide, fittingly there is more engine oil inside the cylinder. This kind of situation mostly happened on those motorcycle used for long year. as a result you compulsion to check the clearance of the two places regularly, correspondingly as to prevent excessive wearout.
- When checking the clearance amid piston and cylinder, you habit to pay more attention to the wearout of piston and piston ring. You habit to put on an act the diameter of the piston skirt and fine-tune piston bearing in mind it come to wear limit. And you moreover habit to check and affect the clearance amongst the piston ring, elasticity and vivacious leakage, and amend the pitch later than it is worn, damaged or achieve the limit.
- Check the clearance amongst the valves and valve guide, you obsession to pay more attention to the wearout of valve stem outside diameter and valve guide inside diameter. Use the outdoor micrometer to affect diameter of the valve stem subsequently repairing, if it reaches the limit, you habit to fine-tune the valve. back measuring valve guide, the carbon growth should be removed by reamer. The reamer should substitute toward the right with taking it into or out of the valve guide, otherwise, it will broken the inner of the guide. Use the boredial indicator to fake inside diameter of the valve guide, it is greater than the limit, next you habit to tweak the valve guide.
The direct cause of blue exhaust is the large clearance betweencheap brakes or valve and valve guide, which is due to exceed wear of these parts. suitably choosing the appropriate lubricant to prevent the excessive wear of engine is an important habit to avoid the blue exhaust. Be sure to use official lubricating oil at indistinctive times, you can pick it according to energetic calendar of your motorcycle.
The white exhaust
White symbolizes purity, concerning everyone can accept it. But bearing in mind the exhaust is thick white in the same way as milk, you should pay more attention of it.
Exhaust in thick white means there is too much water inside the exhaust. There are mainly two reasons:
- You have been fooled by gas station, there is too much water inside the gasoline.
- Or the misery is on your motorcycle itself. The channel gasket or cylinder liner is damaged so that the cooling water come into the cylinder.
Then there is too much water inside the gasoline, in accessory of the white exhaust, it will furthermore cause exhaust pipe blasting or carburetor failure, which will harm the motorcycle sprocket.
You craving to remove the gasoline which contain water in gasoline tank or gasoline channel in time. Besides, if the channel gasket is damaged, you habit to fiddle with it promptly. And if the cylinder liner is damaged, you infatuation to find someone professional to repair it or even regulate it.
