How to troubleshoot a malfunctioning carburetor on a BMW motorcycle?

I recently noticed that my BMW motorcycle's carburetor is not functioning properly. The engine is running rough and it's difficult to start. What could be causing this issue and what steps can I take to troubleshoot it?

First, check the fuel line and filter for any clogs or blockages. Next, inspect the carburetor for any dirt or debris that may be causing it to malfunction. If necessary, clean or rebuild the carburetor. You may also want to check the spark plugs and replace them if needed.

Another possible cause could be a faulty or worn out carburetor float. This can lead to improper fuel flow and affect the engine's performance. Consider replacing the float if necessary. Also check the carburetor's jets and make sure they are clean and properly adjusted.

In addition to these steps, make sure to check the air filter and replace it if it's dirty or clogged. A dirty air filter can also affect the performance of the carburetor. Finally, if all else fails, consider taking your BMW motorcycle to a certified mechanic for further inspection and repair.
