Very cool clip - it almost looks like a steady-cam shot!
I couldn't help but notice as I was trying to figure out which bike was running - is either bike running? Is the sound "dubbed"? I ask because my bike, a B5 with almost 1000 miles now, doesn't sound like this. It has no thump, it idles quite high (compared to your vid), and my auto-decompression would most definitely be clattering away at your video's rpm... wish I knew if it was normal or not. Maybe I should make a video...
