New Moto Guzzi Door Mats Available Now
John, i think this is the one I have on my Breva 750 windshield, the I'm not sure it's much help really, but I haven't ridden behind it much or far. I have adjusted it a few times, seems to hold adjustment etc.https://www.amazon.com/Motoparty-Adjustable-Windshield-Windscreen-windscreen/dp/B07L59965N?th=1Brian
In the position it's in, it works sort of like a Laminar Lip. I wanted a Laminar Lip, but availability is nonexistent. I'm really just trying to make the air flow go a little higher and faster. It does seem to work in that position. I am assuming it compresses the air entering the gap and accelerates it, somewhat like a Laminar Lip apparently does. The angle of attack is what makes a difference, so I am experimenting with that. I kind of like it where it is but have not fully explored all the possibilities as yet. Brian
