What transmission should be changed for domestic GY6125 motorcycles?

GY6 125 is a kind of pedal motorcycle engine, which is a model developed by Taiwan Guangyang on the basis of the introduction of Honda technology. Many domestic small-displement and low-priced motorcycles use imitations of this engine. It is belt-driven and cannot be changed to other transmission methods.

Most electric motorcycles adopt the integrated design of the rear wheel hub and the motor, and the motor directly drives the rear wheel. In this way, the power transmission is more direct, saving parts, reducing costs and failure rate, and is convenient for maintenance and use. Why use a chain or belt transmission?

Buy all spare parts for secondary transmission, including the sprockets and rear wheel gears required after modification. Remove the original chain drive and clean every component.To install new gears, some customized accessories need to be processed to adapt to gear transmission. Install new connecting rod components and new sprockets.

The real GY6 engine belt is the same length, but there are many scooter-like scooters on the market that come from the GY6 variant. The belts of those cars may be a little longer, so they are not exactly the same. There is a model on the belt, and it will not be wrong to report the model when you buy the belt.

The vast majority of the transmission part is belt transmission, which is usually called women's motorcycles. The pedal means that it has a wide foot pedal between the seat and the handlebars. When riding a bicycle, you can put your feet comfortably on it, just like sitting on a chair, without stepping on the car like other cars.

How fast can gy6125 change 200 to run

If it is a water-cooled 200CC engine, the maximum power is 16kW, and the maximum speed can reach 140kmu002F hours per hour.

CC motorcycles have a maximum speed of 100-140 kilometers per hour. Generally, domestic motorcycles can reach a maximum speed of about 90 kilometers per hour; high-performance motorcycles with a displacement of about 1000cc can reach a maximum speed of 300 to 400 kilometers per hour. Take a domestic car as an example.

How fast the Gy6 engine can run depends on how big your throttle is. The minimum yard can reach 30 yards, and the maximum yard can reach more than 140 yards. However, we should still choose according to our own engine function. Which speed should be used more conveniently when refueling the door?

The maximum speed of 200cc of the car is 100~140 kilometers per hour.Strictly speaking, just looking at the displacement can't explain the problem, and the power is the hard truth. And depending on the cooling method, the data of the maximum horsepower is also very different.

If the gy6125 engine breaks out, it won't start for any reason

Look at whether the spark plug is oil or gasoline, whether the car has white smoke, if there is smoke, it means that the piston ring is broken, such as No, it's because the carburetor is broken. You can clean the oil carburetor.

The difficulty of starting the cold car of the pedal motorcycle gy6125 is caused by too low voltage.

In this case, first confirm whether the fuel mixture can reach the combustion chamber. Because it is easy to have such problems when disassembling the middle cylinder. It's better to remove the spark plug first and inject a little gasoline and fuel into the cylinder with a syringe.If there are signs of activation, it will be easy to start. ( Make sure there is enough fuel).

If your car has a feeling of light ignition when it is not on fire, check whether there is a limit plate on your camshaft. If it is damaged or improperly installed, the valve will be closed from time to time, causing the inability to start.

gy6125 electric injection motorcycle can't start. What is the reason why it can start when the throttle valve is disassembled?

1. Analysis problem: This problem usually occurs because the rigidity of the car body is insufficient, resulting in deformation of the vehicle during driving, friction or shaking of the door and the frame, or friction between the steel plates caused by dewelding in some places.

2. The reason why the electric injection motorcycle cannot be hit: the fuel cannot be supplied normally, and the engine temperature is too high. Fuel cannot be supplied normally. Under the condition that there is oil in the fuel tank, check whether there is oil in the carburetor. If there is no oil, it means that the oil line from the fuel tank to the carburetor is blocked and should be cleaned and dredged.

3. The sudden failure of the motorcycle to fire may be caused by the fuel supply system, electronic igniters, spark plugs and other parts.There is a problem with the fuel supply system that can't be ignited; the electronic igniter fails; the battery voltage is too low and the motor speed is insufficient; the spark plug is seriously carbonized or aging; the valve is too carbonized, etc.

4. The starting motor of the electric injection motorcycle rotates. If the engine cannot turn down under the drive of the starting motor, it is caused by a failure of the clutch.

5. Reasons why it is difficult to start a motorcycle: When the cold car starts, the mixed gas is too thin is the main reason for the difficulty of starting. As long as the air barrier is closed, it can be started. Too much oil is given, causing the tank to flood. Whenever it is difficult to start, the more anxious it is, the more it is refueled. The excessive amount of oil in the cylinder causes the spark plug to "drown".

6. There are many possible reasons for the difficulty of starting a motorcycle, which can be mainly summarized into three main aspects, which are: the mixed gas concentration caused by various reasons is not correct, and it is not too thick or too thin.The cylinder pressure is insufficient, the sleeve cylinder is worn or the valve, cylinder pad, etc. are leaking.

gy6125 engine noise is loud...

1. The loud noise of the gy6 engine is basically the timing chain lengthening, the cam rocker arm is worn, the piston skirt is worn, and the front pull plate are Out, the performance is the increase of abnormal noise in the acceleration process. Severe idling speed with severe wear will cause serious noise. Take apart and pick up the engine.

2. There should be no problem with the compression of the new cylinder liner. Check if your silencer has been installed. The noise has little to do with the cylinder liner. The noise of the engine is basically the noise of the crankcase and the cylinder block exhaust. If the engine cylinder block makes a lot of noise, it will be troublesome.

3. It may be that the camshaft and timing chain are not installed, so the tension of the chain is not enough.
