What should I do if the motorcycle throttle doesn't return in winter? The throttle handle has been restored.

Firstly, it is judged whether the throttle valve of carburetor can't return to normal, or whether the engine speed doesn't return to normal or returns to normal slowly after closing the throttle valve. If the carburetor throttle does not return, then the fault is still caused by the throttle pipe, throttle hand and other problems. Just change the throttle line.

If the carburetor is improperly installed, the throttle will be too tight in the carburetor, and some inferior carburetors cannot lower the throttle after tightening the mounting screws. Check whether the throttle valve does not return due to the influence of engine heat on the carburetor. You can choose to install a heat insulation pad to check whether there is a problem with the installation angle of the carburetor, which leads to the throttle valve pipeline being stuck after installation.

The low temperature in winter is not conducive to the start of the engine, and if appropriate measures are not taken, it will accelerate the wear and tear of the engine. Attention should be paid to the following points when using motorcycles in winter:

1. As the temperature drops, it is recommended to use low viscosity engine oil to meet the requirements of engine oil viscosity in winter and prolong the service life of the engine. ?

2. For motorcycles with electric starting system, if the battery is not maintenance-free, the concentration of battery electrolyte should be appropriately increased (adjusted and reduced in time after winter), which can improve the activity of the battery at low temperature and reduce the possibility of vulcanization, and pay attention to supplementary charging. When starting with electricity, if it cannot be started at one time, it should be started at intervals of 10- 15 seconds, and the starting time should not exceed 5 seconds each time. ?

3. For motorcycles that have not been used for a long time, before starting, you should step on the starting lever dozens of times to prevent the lubricating oil from flowing to the friction surface in time to accelerate its wear and even cause a tile burning accident. ?

4. After the cold car starts in winter, the engine must be warmed up for 5 minutes before running, otherwise it will be abnormally worn due to thermal expansion and contraction, which will increase the failure rate of the vehicle over time. ?

5, winter driving should try to reduce the number of car washes, so as to avoid throttle lines, brake lines, etc. Skin damage and water freezing cause accidents. If this happens, under normal circumstances, the branch will be thawed automatically at noon, so please be sure to replace the genuine parts at a competent regular maintenance point. ?
