Common fault of the carburetor: poor transition
The transition is bad
In the process of accelerating from the start, the oil supply of the carburetor idle oil system is gradually reduced to the main oil system. In order to make the oil supply connection between the idle oil system and the main oil system smooth, the transition oil system is set up to ensure the smooth comfort of the starting process of the motorcycle. Poor transition phenomenon: when the start acceleration process, with the throttle open large engine speed fluctuation or flameout.
The reasons for the poor transition and the exclusion methods are as follows:
1. Idle hole, idle oil, main hole, transition hole part blocked
Reason: the idle volume hole, idle oil circuit, main volume hole and transition hole make the oil supply of the carburetor be sparse, causing poor transition.
Exclusion method: clean according to the above carburetor cleaning method.
- Foam tube is blocked
Reason: The function of carburetor foam tube is to promote the mixing of gasoline and air. After the foam hole on the foam tube is blocked by impurities, the mixing effect of gasoline and air is reduced, and the atomization quality decreases, causing poor transition.
Exclusion method: clean according to the above carburetor cleaning method.
- Poor idle speed adjustment
Reason: During the transition process, the carburetor is mainly supplied from the idle oil system. If the idle speed is not adjusted properly, the transition performance will be affected.
Exclusion method: adjust according to the aforementioned idle speed adjustment screw adjustment method.
