Nice video. To help with the rattling of your GoPro (I'm guessing). try putting some toilet paper or other sound absorbent material in there. The Go Pro mic opening is on the bottom left side I think, which the other thing is you can put sound absorbing foam, think old walkman headphone foam, over the mic opening to pick up the chatter and give cleaner sound.
I don't get why you said "trying to keep up". You were doing alright, the only difference I could tell is the Tenere was getting on the drive sooner coming out of the corner, just made it seem like he was going faster.
I love roads like that, and Cambo, I think I've finally figured out where all your love comes from. You just may be an 80 year old woman, and like all grandmas you love everybody. Cambo once you get riding down and start looking through the corners it really isn't that bad. I need to edit my video from my CO trip, I was doing the same kind of speeds in the rain with 200 foot drop offs on the side. Trust the motorcycle, it's a lot more capable than you are.
