I believe reduced airflow would cause a rich condition.

An idea I had was to mill an opening in the top of the oval aircleaner and use one of those 9" round open top air cleaner lids you can buy at summit. It would add airflow directly above the carb and the wingnut would hold it all together.

You can also buy the oval open top from Summit but it doesn't say Cobra on it. It's also a few inches shorter in length.

Custom billet drop base air cleaner assemblies just sounds expensive.
