Why can't the needle of the original motorcycle carburetor be adjusted?
1 Answers
The reasons why the needle of the original motorcycle carburetor cannot be adjusted are as follows: Cannot be adjusted during operation: Even for adjustable motorcycle carburetor needles, most of them cannot be adjusted during use. If adjusted, it will cause the carburetor to malfunction. When the carburetor needs adjustment: Incomplete combustion: The main symptom of this issue is black smoke coming from the exhaust pipe. At this time, the problem can be improved and solved by adjusting the position of the main needle and the liquid level height. Poor fuel supply: This issue is mainly caused by an overly lean air-fuel mixture. Similarly, it can be solved by adjusting the position of the main needle and the liquid level height.
