X-Mas Sopping on Spyder

[Dan_Ashley]

On the way home from X-Mas shopping, with stuff filling my frunk, I collided with a swarm of bugs. Bug juice on my helmet--ALOT! Bug juice on my windshield--some. Bug juice on my gloves!

But out what really gets me is how, at 75 MPH, does bug juice get on the backside of the windshield! How come is that?

Nice day to ride though. BUT I GONNA TAKE A CAN OF RAID WITH ME NEXT TIME. THAT'LL FIX 'EM. I'LL SPRAY 'EM AS I GO DOWN THE FREEWAY!!! hyea:hyea:

The amount of wind that comes up the backside of the windshield would amaze you. It needs to be that way to limit wind buffeting and turbulence, but it can be substantial. Turbulence and backdraft can add to it. In a rain, the back of my windshield is often wetter than the front (and dirtier). I have never cleaned my windshield without finding several bug splats on the back...even on other bikes. The old Vetter on my BMW Slash 5 being the possible exception. That had a lot of still air in the back.

Bombs..!!

a bug bomb launcher to clear you a path..just be glad they are not a swarm of bees crossing over to pollinate fields on the other side of the freeway. Don't ask..!!

Speaking about turbulence and backdraft behind the windshield, I once found myself riding through rain (all of a sudden) and was amazed when I noticed a few droplets suspended in mid-air on a back side of my windshield. I couldn't believe my eyes.

Killing bugs with my spyder is effective-- they all die. But methinks a 20 gallon tank of insecticide mounted on the front of the spyder with 140 PSI sprayer would be better.

How come is that?

Ummmm...

Di you ever notice water droplets moving from bottom, to top on your visor? :shocked:
That's the backdraft and turbulence playing with you!

You've got a high pressure area on the front of the windshield via the impacting air and a low pressure area behind the windscreen. A windshield vent will alleviate some of the pressure differential and lessen the amount of rain, bugs, etc on the inside of the windscreen. I cut a NACA shaped inlet on my BRP sport windscreen and it made a big diff.

...Even the 2013 oem windshield's small vents help a lot in reducing the turbulence... :thumbup:

Gee!!! Are we talking NASCAR Again. I thought Downforce and lift are not part on spyders?
