How to solve the lack of power of motorcycles

What should I do if the motorcycle won't tilt? The master teaches you that you can easily warp your head at home by adjusting only one screw.

Generally, the following checks can be done: cleaning the spark plug (or replacement), and checking the current of the high-voltage bag.

There are many reasons for the lack of power of the scooter, in addition to the small engine displacement and limited power performance, the lack of power caused by the failure mainly includes the air filter, carburetor or exhaust pipe blockage, improper adjustment of the carburetor mixing ratio, the failure of the electronically controlled damper to cause the mixture to be thick, the quality of the carburetor itself is poor, the negative pressure fuel tank switch from the suction pipe causes the mixture to be thick, the cylinder block, piston, piston ring wear causes the cylinder pressure to be low, and the valve is not closed tightly and leaks. Insufficient intake and exhaust due to worn camshaft and valve rocker arms, poor spark plugs or weak high voltage, poor gasoline oil quality, too much oil in the engine, and wear and slippage of the transmission system such as belts, pulleys and pulleys are common causes of scooter underpower.

Hello The reasons why the scooter is not uphill: 1. The concentration of the carburetor mixture is too low, which causes the uphill weakness. The solution can be solved by adjusting the oil-gas mixing ratio of the carburetor.

2. The transmission belt is seriously worn, resulting in uphill weakness. The solution can be solved by replacing the new transmission belt. 3. The engine cylinder, piston and piston ring are seriously worn (pull cylinder) and the sealing is not tight, resulting in uphill weakness.

The solution can be solved by replacing the cylinder, piston and piston ring.

I hope mine can help you.

Questions. It was the new car that only ran 4,000 kilometers, and the 250 did not have the strength of the 125.

The reasons why there is no force in the new car and motorcycle: 1. Poor contact of the electric door switch, or poor contact of a certain line on the ignition, causing abnormal ignition, of course, it is not ruled out that there is a problem with the ignition. 2. Check whether the belt of the transmission has become longer and cause slippage, and the pulley beads and pulleys may be worn.

3. If the air filter and exhaust pipe are blocked, insufficient intake and exhaust will also cause weakness. 4. If the carburetor mixing ratio is messy, or blocked, there will be similar problems, the scooter has an electronic damper, check whether the electronic damper is open. 5. The negative pressure switch of the oil tank is abnormal, which causes the oil to be unsmooth.

6. If the camshaft and valve rocker arm are worn, it will cause abnormal intake and exhaust 7. If there is air in the oil pipe, the oil supply will be discontinuous due to the shaking of the fuel tank when going uphill. 8. Whether the spark plug is leaking. Additional Information:

The circuit is mainly to check the high-voltage spark, if the ignition system high and low voltage components and circuits can cause high-voltage flashover discontinuity, it will cause the engine to work intermittently to make the acceleration weak or the ignition circuit electrical components and circuit faults cause the high-voltage power is too weak, and the engine will work poorly.

One is the lack of power caused by the weakness of the car, the engine speed can not go up, you need to check the running status of the engine, whether the oil inlet is insufficient, whether the air filter is blocked, whether the exhaust is not smooth, whether the high voltage is normal, one is that the engine has a speed and strong power, but the car power is low, you need to check whether the brake pads are back to normal, whether the components in the transmission (box) are worn and aged, etc., find a maintenance worker to test confirm

Check the air filter first, if it is dirty or damp, bask in the sun and blow it with compressed air to clean it.

Replace if necessary.

Check the spark plug again and replace it if it is black.

Check these two items, and if the problem isn't already resolved, consider gasoline and the ignition system, with the latter as the focus.

For example, whether the high-pressure bag, igniter, etc. are faulty or falsely connected.

125 Motorcycle Engine Insufficient Power Causes:

Extrinsic causes. The external reasons for the lack of power of the motorcycle are mainly insufficient tire pressure, the brake clearance is too small, the chain is too tight, and the lubricating oil has not been replaced for a long time.

Intrinsic causes. There are many internal reasons for the lack of power of motorcycles, but they can be summarized into the following three categories.

1. The oil supply system, air filter blockage, mixture too thick or too thin will cause, the current vehicle power declines, and the simple and effective way to troubleshoot is to look at the exhaust pipe exhaust color first, and then look at the spark plug. (More on that later).

2. The transmission system of the motorcycle is relatively simple, and the reason for the lack of power is nothing more than the clutch slippage, so the fault can be eliminated by checking the clutch.

3. Normal wear and human factors such as internal faults, aging valves and piston rings, pulling the cylinder block, and wearing the rocker arm of the camshaft will cause the power of the motorcycle to decline.

Figure out the main reason for the decline in motorcycle power, then you can eliminate it according to the specific fault performance of the current vehicle, and the probability of insufficient motorcycle power will be relatively large because of the fuel supply system and transmission system in actual use, so the focus can be on troubleshooting from these two directions.

Insufficient engine power and poor acceleration are generally caused by low fuel pressure, poor fuel injection of injectors, low ignition high pressure or low energy, incorrect ignition timing, low cylinder compression pressure and blocked exhaust pipe. In general, the specific cause of the failure can be determined by checking as follows:

1. Press the accelerator pedal to the end and check whether the throttle can be fully opened. If it can't be fully opened, adjust the throttle cable or pedal. 2. Check whether the air intake system is blocked or leaking.

If the air intake system is clogged or leaking, it will inevitably affect the charging efficiency of the engine, resulting in a decrease in engine power and acceleration performance. Specifically, the air filter, air intake duct and various vacuum hoses should be inspected for blockages or air leaks.

3. Check whether the exhaust system is blocked. The back pressure of the exhaust system is generally controlled within one atmosphere, if the back pressure of the exhaust system is too large due to the blockage of the exhaust pipe, it will inevitably cause the residual exhaust gas content in the cylinder to increase, thereby causing the combustion rate of the mixture to decrease, and the effective pressure of the cylinder to decrease. The main reasons for the increase in the back pressure of the exhaust system are blocked exhaust pipes, deformation of the exhaust muffler or three-way catalytic converter, etc., and these components should be inspected.

4. Check whether the fuel supply of the fuel system is normal. Check the pressure in the fuel system. If the pressure of the fuel system is abnormal, especially when the pressure of the fuel system is too low, the fuel injection volume of the injector will decrease per unit time, resulting in the mixture being too thin, and the power of the engine will be greatly reduced, resulting in insufficient engine power and poor acceleration.

It may be that the oil supply is insufficient, and it is better to check the carburetor.

Hello, I am helping you sort out the answer to your question, please wait a while Hello, the motorcycle engine is not powerful enough, in this case, first check whether the spark plug is aging? If it is aging, it is recommended to replace the spark plug first, if there is no problem, this check to see if it is a problem with the carburetor. This is also true if the carburetor is too dirty.

Questions. Is the carburetor dry?

Remove the carburetor and clean it, is this one of you EFI, or carburetor? It needs to be determined, if it is EFI, disassemble and clean the throttle, if it is a carburetor, this is the carburetor that needs to be cleaned.

Questions. Carburetors, without a drop of oil a lot of dust.

The carburetor is only oiled normally when it is working, and if there is a lot of dust, it is recommended to clean it first.

After the mixing ratio and idle speed of the motorcycle are adjusted to good, if the driving performance is still good after driving for several kilometers, and then if the starting driving performance is reduced after driving thousands of kilometers, try not to use the idle speed and mixing ratio, especially the mixing ratio, unless it is confirmed that the adjustment screw has changed. This is where the spark plugs and air filters should be inspected or replaced, as well as the gasoline and lubricating oil should be checked to check for loose tightening screws. That is, to check the circuit oil circuit and gas circuit.

Regular bikes are sensitive to climatic influences, so be careful not to adjust the mix ratio and idle speed that have already been adjusted.

Other reasons: The motorcycle becomes weak and difficult to speed up the whole reason.

1. The engine power is insufficient, the displacement is small or the cylinder pressure is insufficient.

For example, the cylinder gasket is damaged, the cylinder or ring is worn, the valve is deposited, and the piston ring is installed in the wrong position or becomes wrong (there are specific requirements for the position of the oil ring, the air ring ring and the position of the parallel notch).

2. The clutch is seriously worn or the compression spring is loose and slippery;

3. The transmission chain is too tight or the transmission belt is too loose.

4. The brake is in a semi-braking state, and the brake is not fully returned.

5. The wheel hub or bearing fails to rotate flexibly.

6. The air inside the tire is not full enough and is a little soft.

7. Too little or too much lubricating oil or failure, resulting in air leakage of piston rings or increased resistance of several pieces.

8. The oil tank switch or oil pipe or carburetor is too dirty and blocked, resulting in poor oil.

9. The air filter or exhaust pipe or the snorkel and hole on the engine, reverse, gear pack, fuel tank, etc. are completely blocked.

10. The connection between the engine and the carburetor leaks or the air filter is not installed.

11. The mixture is too thin (lean oil) or too concentrated (rich oil), or the fuel oil becomes substandard.

12. Hardware damage, such as cylinder head, cam, valve (valve spring broken or too soft, valve bending, etc.), rocker arm, cylinder barrel, engine shell, internal parts, etc.

13. The valve clearance is too large or too small.

14. The front wheel and the rear wheel are not in a straight line.

15. The spark plug installation hole leaks air or the spark plug grade is too low or there is quality loss.

16. The engine is overheated.

17. The adjustment of the main oil needle of the carburetor is too low or too high, and the adjustment of the oil level is too low or too high.

18. The main oil volume hole of the carburetor is loose, the main air volume hole of the carburetor is blocked, and the carburetor enrichment system cannot be returned. ．

19. Circuit problems, incoherent high-voltage ignition, fire failure, or high-voltage sparks are not strong enough, or there is leakage.

20. Accessories failure: such as ignition, high-voltage bag, high-voltage cap, spark plug and other problems, or the above circuits have open circuits or short circuits or virtual connections.

21. Magneto failure.

There are many reasons for the decline of motorcycle power, and many parts of the motorcycle and engine will gradually wear out with the use of motorcycles, which will affect the power performance. The common reasons that affect the power mainly include air filter, carburetor and exhaust pipe blockage, improper debugging of carburetor mixing ratio, oil level, oil needle, etc., or aging of the carburetor itself, clutch slippage, cylinder pressure drop, poor oil, camshaft and valve rocker arm wear, etc.

What's the deal with the motorcycle engine being hot.

If the run-in period is not good, it is necessary to replace the new parts with new parts to re-run-in.

You're talking about heat decay, right?

The power of the motorcycle comes from the engine, which has 2 chambers, separated by pistons... There can be no air leakage between the 2 rooms...

However, junior high school physics students know that there is a property called thermal expansion and contraction, and the value of thermal expansion and contraction of different materials and sizes is different...

Then, the problem is that when the engine temperature rises, it is possible that the size of the piston will increase by value, and it will not be able to keep up with the increase in the cylinder barrel, and there will be a gap between the two chambers that were originally sealed.

There is an air leak, so the power drops, commonly known as thermal decay.

Clutch wear, oil change and clutch plate are more than 70 oceans.

Check the carburetor. Mix ratio. Replace the spark plug. Oil.

Is it okay to change the rear drum brake of a motorcycle to a disc brake?

Hello dear <>

Yes. Hello dear <>

But there are a few things to keep in mind:1Confirm the compatibility of the replacement disc brake kit.

There may be differences in the disc brake kit for different models, so you need to choose a kit that is compatible with your motorcycle. 2.Confirm whether the braking force distribution before and after the disc brake change is reasonable.

After the disc brakes are replaced, the distribution of braking force between the front and rear of the vehicle may be changed, and adjustments need to be made to ensure stable braking performance. 3.Confirm disc brake life.

The service life of disc brakes may be affected by factors such as the way the vehicle is used and road conditions, and it needs to be replaced in time to ensure safety. 4.Confirm the cost of consumables for the disc brake.
