I had been considering NACA ducts just behind the blinkers. There is a triangle drawn in texta on my faring. I was considering running C/F tubes to flex hose connected to the top of my C/F glove box. I was also thinking about running tunnels from the grill.
That sound deadened cover was lifting at 60/65mph. It was flexing the lightweight C/F cover out of its clip. I had designed it to be easy to remove but still it was being blown of. I could feel the rushing cool air when i put my naked hand next to the carbes. The same hand next to the radiator was bathed in warmth There is simply no reason to bring air to the air box as it has ample when moving
That's good info. I've cut the bottom of the shelf in my glove box off to make room for sensors. I could do the same thing and see if their is some pressure in there. I usually have a tank bag on that holds my wide band and data logging so my glove box is always strapped down. Your shrouds are helping alot. A 950 that doesn't run the fan in Summer traffic
.Great idea. I suspect that the fork legs create vortexes that probably spill over the stock fairing. The notch only being three inches from the radiator. Speculation of course since you can't really tell what's going on unless your in a wind tunnel. I've done some aero testing with various teams I've worked for. Some even had a big enough budget to afford wind tunnel testing. I thought that would be fun but it is one boring day I tell you. Looks like you have more than doubled that distance plus widened it out a couple inches. Nice mod with good results.
Suppose I could data log the airbox pressure sensor. Do some pulls on the dyno with no fans for a base line setting, then go ride and see what I get.
