What's the matter with the vibration of the Sanmo engine?

The engine fixing screw is loose. According to the query Mobi.com, the engine fixing screw is loose or the large frame is broken, because once the tricycle has a problem in these two places, it will shake when starting. At this time, you need to go to the repair shop for maintenance.

The specific reason for the unstable shaking of the car engine; excessive carbon accumulation in the engine: When there is too much carbon accumulation inside the engine, the gasoline sprayed by the fuel nozzle of the starting vehicle will be absorbed by a large amount of carbon accumulation, resulting in the mixture being too thin and difficult to start.The vehicle is easy to start only when the carbon-absorbed gasoline is saturated.

First, the quality of the car is not good. Second, the engine does not have its own balance shaft or is not a chain machine. Third, the large screw of the engine is loose, just tighten it.

Is the Sanma 150 and 200 Zongshen engines universal over the clutch?

It depends on the brand. For example, Zongbai's 200 displacement du is 3 kilowatts, while the 150 displacement is only 5 kilowatts, and the difference in power rate is 8 kilowatts. In other words, 200 is more than 20% stronger than 150. If it is the same type of engine, the difference is the piston diameter and piston stroke, and everything else is the same.

Universal, as long as they are all new widening tablets, only 200 seven pieces and 150 six pieces. If you have any other questions, you can continue to ask me.

As long as the engine size and model are similar, the 200 engine can be replaced with a 150 engine assembly, but for tricycles, the power of 150 is smaller, which is more prone to failure and the life of the engine may be shorter.

No. The 200 and 250 surpass clutches are not universal. It is not allowed to change the tricycle 250 surpass clutch to 200.

Which company produces the Dajiang brand 125 three-wheeled water-cooled engine vertical engine?

1. Of course, the Dajiang tricycle is produced by Dajiang. The engines of this kind of three-wheeled motorcycle are all imitations of the Honda CG top-bar machine. The old top-rod machine in the 1980s, the technology that Japan does not want is passed on to China.

2. Because the Dajiang tricycle pickup fuel model is developed and produced by Hebei Everest Dajiang tricycle Motorcycle Co., Ltd., the engine is a water-cooled model, so there is a diesel motorcycle tricycle. Hebei Zhufeng Dajiang Tricycle Co., Ltd. is a joint venture specializing in the production of tricycles, mainly engaged in Dajiang brand tricycles.

3. No. The Dajiang three-wheeled pickup truck fuel type is developed and produced by Hebei Everest Dajiang Three-wheeled Motorcycle Co., Ltd. The engine is a water-cooled model.

There is an electric current sound as soon as the gasoline Sanmo key is turned on the horn

1. Line failure, just clean it up, or a speaker wire is mistakenly connected to the power cord, or the horn switch is broken and there is a short circuit phenomenon.

2. Hello, according to your description. It is necessary to judge whether the sound comes from the speaker or the buzzer. If it is from the speaker, it means that there is an interference signal. The specifics can only be judged after professional inspection.

3. The reason why the key of the electric bicycle rings as soon as the horn is turned on is that the circuit of the horn is on.It may be that the switch in the circuit of the speaker is broken (change the switch); or there is a short circuit somewhere in the circuit of the speaker (isolate the short circuit with insulating tape).

4. But the current is relatively small, so the speaker can't make a sound normally. The problem encountered by the questioner may not be the problem of the electric bicycle, but the nature is the same. Since the switch is flooded, the switch can only be dried. It is best to remove the wiring point and clean it up, so as to avoid moisture staying in the hidden place and corroding the wires and wiring poles for a long time.

5. It is connected according to the time of anti-theft installation. So you don't want the key to ring when you turn on the key.
