As an interim step I raised my gauge cowl up. Got the idea from another member on this forum. It works well. Takes the wind off of my chest, helmet is in clean air. Ultimately will look for another solution, but it works...
Buy an F4 and never look back. They are a little higher in price than other aftermarket shields but in this case you truly get what you pay for. You can actually clean them without worrying about scratches, they are optically correct, and will last the life of your bike

Agree with F4, took a trip to Streetsboro, Ohio last year and Don and crew installed what I guess was the 1st production run on a 28" tint on my F3S, 14,000 miles later it still looks like new...
