In order to ensure a good technical state in motorcycles，Each component has good working performance，Effective maintenance and maintenance is performed according to the wear rules and technical conditions of the part.，It is best to play the performance of the engine，Extend the life of the engine。
1。 Engine operation
1。 begin
①。 Make the engine gear，Then start with electricity or pedal。Start the engine when it is hosted，Otherwise, it will cause mechanical damage.（For example, clutch overspeed，Start the gear is broken and many more）Incident；
②If the engine is in a cold state，Need to rotate the throttle to completely close，closekeDoctors start，This step can be omitted；
③Under extreme cold conditions，Before starting the engine，Use the starter multiple drive crankshaft，Make lubricants to lubricate cylinders，Then start the engine according to the cold program；
④。 Stepping start engine，At startup，Slightly open the throttle，And quickly rebound quickly with the right foot，From the top of the stroke to the bottom of the stroke，Simultaneously， Be careful not to let the boot arm rebounded and hit the pedal limit board.，Apart from this， The engine can be damaged；
⑤After the engine starts，Place the throttle door in a semi-open location，Open the throne door after half a minute，Adjusting idle speed，Use the engine to run normally。I don't want to hurry for a long time.，Idle or idle speed，In order to protect engine power，Simultaneously， Can avoid waste of fuel。
2。 Change file
For manual clutch engines， They are arranged according to the gear position of the engine，You can follow the steps below：
①Engine is idling，The clutch handle should be tightly grasped，Use the left foot to change1Document or lower gear；
②， Gradually turn the throttle handle，Then slowly release the clutch handle to let these two sports work together，To ensure smooth start，Not in a hurry
③。 When the motorcycle reaches a stable driving state，Turn off the throttle，Firmly grasp the clutch handle，Use left foot to control shift，Can be added to2Document or higher gear；
④When the motorcycle is on the mountain，If you use high-end driving，You will feel insufficient power，It will stop retreat， Wait for switching to low speed； Down the mountain，Do not hang the high end to drive or switch to the low speed in the original gear，Don't be too fast to master the appropriate speed。
special reminder：When the clutch is not loosen, the throttle is reduced.，Be banned，Apart from this， engine， Transmission chains and other parts will be damaged。
3。 New car
The sound combination of new cars directly affects the service life of the whole vehicle.。Really driving in the new car1000Kilometers，Strictly prohibiting engine speeds exceeding6500rpm（Driving speed does not exceed40Km / h），Avoid all-air doors，Then select the speed such that each gear has an appropriate mileage，Reduce excessive force to the engine。
During the initial mill， Mill should be carried out cautious。Maintenance after moving，Its purpose is to compensate for the initial slight wear，This will greatly extend the life of the engine，Make sure the engine is in optimal state and good performance。
①Mulled phase，Preheat the engine in front of the driving，First driving at a low speed1Km-2Km，Then switch to high-end driving；
②In order to reduce vibration and impact load，Choose flat flat road during the day；
③， Timely shift when the engine load is increased, if you barely drive，It will cause an engine abnormally or damaged parts，Avoid working under heavy load；
④During running，The load must not exceed the rated load80％，And strict control speed；
⑤Frequently check whether the amount of engine lubricants meets the requirements；Excessive heat during driving，The reason should be found in time，Timely exclude；
⑥。 Frequently check the free trip of the clutch and throttle handle。Adjustment if necessary。
2。 Engine repair
After driving a certain mileage, its technical conditions are gradually deteriorated.，Technical status according to different miles，Conduct different levels of maintenance：
1Level maintenance：driven distance1000Km-2000Km，Maintenance operations with lubrication and firmness；
Secondary maintenance：mileage2000Km-6000Km，Maintenance work to check and adjust as the main content；
Three-level maintenance：mileage6000Km-10000Km，，Removal maintenance Assembly decomposition and inspection 易彤料理机修理 Eliminate hidden dangers as the main content；
meal，For different seasons Different regions And different conditions of use，Maintenance requirements also different maintenance according to the actual situation。
（One：checking， clean Adjustment， Lubrication or replacement； C：clean； R：replace； answer：Adjustment； L：lubricating）
3。 Use and maintenance of replacement and accessories
1。 Conversion lubricant
The quality of the lubricant should be checked.，If it becomes black， Drape like water emulsification and many more，Should be replaced in time，And when the engine is replaced when the heat power equivalent machine。
Confirmed that the oil has been used，Add qualified oil，Start engine，Let the engine idle2min?3min，Then stop the engine speed to wait a few minutes to deduct when the motorcycle brand is in a vertical position.，Check and confirm if the oil level is in the highest oil level mark of the amount of the oil，If necessary，Come on, check if it is oil。
2。 Cleaning oil filter
Timely cleaning filter，It can effectively prevent the lubrication system from being blocked by the oil path，Machine damage，Remove the filter，Cleaning the filter with cleaning solvent。Simultaneously， Check if the filter screen is Sealing glue spring， OThe shape of the column and the dramatic stroke are good。
3。 Clean or replace spark plug
The insulator skirt of the normal temperature spark plug is brown，Skirt is as grayish This means that the work environment is overheating； When there is a metal melted bead, the work environment of the frog is seriously overheating.，Cause should be investigated in time。
For the spark plug，Soak gasoline after half an hour，Carbon and dirt from the spark plug with non-metal scraper，Finally, use gasoline and check if the spark plug is damaged.，Whether the electrode is ablated or not in a good condition。If it is damaged, it should be replaced.。
4。 Clutch adjustment
Clutch control engine power output，Power cannot be transmitted in separate； The power is transmitted to the rear shift through the crankshaft when it is combined.，right now，The rear wheel is driven by the chain。
Clutch should be thorough，Separate，This requires its handle to have free travel。Free travel in clutch tip measurement15mm?20mm，If the free trip is adjusted，Shift，This will cause the clutch slip，Or after the clutch is separated，Vehicles still have advanced trends。
5， Adjustment of vacant speed of carbers
Start the engine and warm up，Before continuing operation，Let the temperature slightly higher。High-speed empty screw，Adjust the idle speed to（1500±50rpm，Check when turning the throttle knob，Whether the engine speed is stable。Adjust the idle speed using the idling screw1500rpm，If the engine is not working properly，Repeat the above steps。
6。 Clean air filter
When the air filter filter is blocked by dust，Increase intake resistance，The mixture is too thick, the power drop fuel consumption is increased.，Cleaning regularly。
Under normal circumstances2000Km-3000KmClean an air filter，If you travel for a long time in a dusty environment，The cleaning cycle of the air filter should also be shortened。
Remove the air filter，If it is a sponge filter，You can pour kerosene or non-fuel cleaner into a suitable size basin，Immerse the filter into the detergent。Pull a little and then put it and check if there is break or crack.，If，Should be replaced with new products。
Immerse the filter in clean after cleaningHOB-10Lubricant until saturated，Excessive lubricant。Wipe the lumen of the filter with a clean dry cloth。
special reminder：
★Do not use a solvent cleaning filter with a low gasoline or low-fire spot。Otherwise it will cause fire or explosion；
★Do not clean the filter in gasoline， Acidic Alkaline and organic volatile oil Watro, because this can cause the core aging，And make the filter stick failed。
