Gotcha! Thank you.
I installed mirror extenders a couple years back. Bought a generic set for amazon.ca for $15. Difficult to find because the threading is not always listed in the details
I want to state something before I start typing. I do not try to prove points, I never have to be "right," I love to learn and also share, and am a total geek when it comes to just about anything I'm interested in. I'm the new guy here (though I think we've chatted on advrider) and don't want anyone to think I'm some kind of know-it-all blowhard...who has to prove points and be right. Those traits are not in my nature.
The timing could not have been better to have been caught in a little bit of a downpour today. My theory on the detents and the mirrors (both OEM) causing turbulence is spot on. The water comes up from the detent and hits the traffic side of the mirror just at the apex. The forward force at the apex of the mirror forced the water to about 5:00 or 150 degrees. It curves slightly up then down into the rider's torso. I'll follow your lead first with the extenders and the screen I was changing anyhow. Interesting too was that it was more pronounced on the left side of the bike than the right. I don't know if the direction of travel (east) had anything to do with that.
Every post I make has nothing but good intentions! I don't want to be "that guy." Sorry to go on about that but I have a lot to learn on this bike and don't want to be blackballed. I thought it was interesting and timely too!
Complete aside, really handled wet Florida asphalt well!
