• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Windshield Bug Splatter/Juice

Okay, I've oftened wondered about this, but never had the courage or stupidity to pose the question. Went on a nice breakfast run today and came back with a windshield plastered with bugs on the front and backside. How do bugs get splatterd on the backside/inside (driver's side) of the windshield? Is there some sort of cosmic force that's involved, some rules of science that applies? And I don't ride backwards at any time other then to back up at low speeds. As you can tell, I've probably got a little too much time on my hands this Easter Holiday, but cleaning all the bug juice off has made me wonder why this occurs. Besides, having to clean the Spyder allows me to miss the strategy session regarding where to hide Easter Eggs for grandkids.

That's a natural low pressure area, the front of your windshield pushes the air out and away so a vacuum exists behind the windshield. The air around you tries to rush in to equalize the pressure. Semi trucks sometimes have additional panels off the back of the trailer to rid themselves of the drag from this, NASCAR loves to draft one another to slingshot ahead with it, Bernoulli Priciple uses it to describe lift of aircraft.

I have a cal/sci windshield with the hole in the middle down low. I always thought that is was there to let air pass through but not. I put my hand there testing my extension and the air goes back through the hole relieving the back pressure. My extension sets almost 2 inches off the windshield and up a bit. I also thought the air would pass through defeating the extension but the air is pushed up and over my head. My eyes are just above the extension and if I lean forward a bit, I am below it. No bugs as they go back through the hole I guess.

I believe that it's a corollary to Murphy's Law:
Bug debris will always get in the darndest places right before you realize that you've run out of time to clean the bike again before the next ride! :gaah:
