For those of us who have invested in expensive Madstad screens, it's almost a solution, but for me there was still some peak buffeting and I was fairly sure where it was coming from - you just have to hold your hand in front of you at various positions to feel where the turbulent air is coming from.
I had hoped that the new visor kit from Honda shown in this picture would have allowed me to revert to the standard screen:
But - No - you can, I hope, see the problem. There's a big gap between the top of the visors and the start of the screen. Honda have to do this because the knuckle guards would impact anything that is in that space when on full lock.
Now here's a pic of why the Madstad helps a lot - it's about 4 inches wider. (ignore the frost on the screen - it comes clear
The reason they can make it wider is that they bring it forwards by about 2 inches. But I think you can see that there is still a bit of a gap at the critical points.
....... so .... I thought I would try filling those gaps in temporarily with adhesive tape.
This first pic shows how i simply applied 3 strips across the all important gap:
and this second pic from the riding position shows better how the airflow at this point is cut off by the tape:
There is still a huge amount of air flowing up under the screen centre as I have the screen raked back quite a lot.
BUT blocking off these two side gaps has just about eliminated the buffeting (at any speed).
Now all I have to do is work out a way of making something that looks better than Gaffa tape.
