1. Air oil filter is blocked
Motorcycle air filter is easy to dirty, because a lot of motorcycle ran in national highway, provincial highway and country dirt road, the local air quality sounds good to me, in fact, because of the dust float in the sky, empty filter is easy to dirty, and also the one who usually ride a motorcycle don't like drive a car then attaches great importance to the maintenance, a lot of use of more than 10000 kilometers did not replace the air filter, then cause a serious shortage of air volume, engine, of course, is not doing work, running speed up, not climb up a small slope.
In addition to the empty filter, gasoline filter if blocked, directly cause the oil supply is not normal, but gasoline filter service time is generally longer, as long as you add the quality of gasoline can, many are more than 30,000 kilometers of life.
Most motorcycles without oil filter element, and only filter, filter if blocked, will cause abnormal oil lubrication, engine easily heat damage, generally in the oil change, can be properly checked and cleaned.
2. Abnormal oil supply system
In addition to the above mentioned gasoline filter blockage caused by unreasonable oil supply, does not exclude the oil pipe bending or blockage and other problems, you can pull out the oil pipe to see if the oil is normal.
Past motorcycle carburetor oil supply, carburetor factory air-fuel ratio has been adjusted, when oil also match the correct needle position, usually don't have to adjust, but does not exclude the use after a long time, or add some oil quality is bad, cause inside the oil out of proportion, you can find some dedicated carburetor cleaner to wash. If the mixing ratio is disordered, it will also cause unsatisfactory combustion. At this time, the output torque of the engine will be severely reduced, and the exhaust pipe may emit black smoke.
Now is the electric spray car, when the factory is strictly matched parameters, consistency is relatively ideal, but also do not exclude the exception of individual models. If it is a new car climbing is not normal, you can find a merchant to help you adjust the match, or replace a sensor.
Electric spray car has oil pump, nozzle, oxygen sensor, pressure and temperature sensor, throttle position sensor and so on, if there is a piece of accessories is broken, or poor performance, this time the engine will seriously deviate from the normal state, climb up the slope is a matter of course. Or use time is long, the probability that plug gives a problem is higher also, want to think carefully to this side.
No matter electric spray car or carburetor car, there is an ignition system, but electric spray car generally ignition unit, integrated into the ECU inside, external or the same to drive the high voltage package and spark plug work. If the igniter is used for a long time, the performance of the transistors inside will be reduced, or the capacitance capacity will be reduced, which will cause the output power and torque of the engine to drop, and it will not run when climbing hills.
If the spark plug is ablated, it may cause fire leakage or break. At this time, it is obviously unable to run, or there is a slow down phenomenon. Climbing is more of a problem.
Although less bad, but high pressure cap often because of high temperature heat damage is relatively common, can directly cause abnormal ignition, when climbing the slope, do not rule out not ideal.
There are some old cars, if the line is aging, or damaged, will cause leakage of electricity leakage fire, cause engine control failure, these have to be carefully analyzed and found.
4. Clutch problem
Clutch is to connect the engine flywheel and transmission between the power transmission mechanism, it is completely dependent on the pressure plate and friction plate friction to achieve, if there is a slip between the two, directly caused by the wheel torque shortage, climbing is not normal.
You can hit the big foot, after the car is empty, put into gear, if the oil door to see the rear wheel rotation is slow, you lightly step on the brake, the rear wheel may stop, this situation can be determined as the clutch burning plate skid.
Also can hang up the gear, try to push the motorcycle around, if you feel very difficult to push, it means the clutch is normal, if it is easy to push, it means there is a slip in the clutch.
That is, the essence of clutch skidding, is that the engine speed can go up, but the wheel speed can not go up.
5. Engine problems
Some people just to buy a new motorcycle, go to the high speed, although now a lot of joint venture car of good quality, but a motorcycle or car manufacturing level difference, gearing is necessary in the running-in period, high speed, no rejection cause harm to the wear and tear ", cause such problems as lack of engine cylinder pressure, at that time couldn't climb the hill is not surprising.
The car has been used for a long time, or did not change the oil in time, the valve, rocker arm, piston ring, cylinder wall, camshaft, etc., may produce wear, oil burning, will directly cause serious decline in engine power and power, climb the slope of the natural.
6. Improper operation
If it is a scooter climbing difficult, there are chutu sound, this situation is the engine speed is too low caused by, can be in the slope before the throttle a little larger, let the speed up after the climb.
If you are still in the turning state when climbing, you need to put the oil door and a little touch on the brake, so as to ensure the safety of low-speed turning, while the accelerator can maintain the high speed of the engine, and release the brake when coming out of the corner
