Initially, I couldn't tell if the spoiler did much at all. It didn't seem to stop the wind when in the most upright position.
Once I had it on for a while, I noticed a huge difference between the "off" position and the upright position. I guess it just took me a while to get what it was doing.
I use the off position when it's hot out, or when I want more wind pushing on me. In the on position, it keeps the cold off me, and also removes about 70% of the harsh wind that hits my upper chest. It doesn't do a whole lot for my helmet, which is what I was initially looking for. I also use it to keep rain and bugs off me.
Yeah, it's not a "huge" difference, which is what I had initially wanted. But I have close to 50k miles with it now, and I'm happy overall with it. In full up position it will take a good chunk of the wind blast off me when cold out. I find on the busa though, you get a lot of wind blast from the mirrors too - so the shield will only mitigate a small section right in the middle.
