I actually had the fun of riding quite a lot in No Cal in 2008 with a buddy of mine from another forum. We did Hwy 36, Skaggs Springs Road to the Pacific, and several others which I forget the names of. It was mega. I was jet-lagged from flying from the UK but we still did about 600 miles in 36 hours.IF you get to northern California check out Mesquito Ridge Road 600 curves in 36 miles.
The growl come from the intake just below the headlights. Mount it there and you'll get the sound.Just the stock cans, and I'm frustrated I can't capture the wonderful Triumph Triple growl when the engine opens up to full power. I'm still working on that. The cam I am using is this one
The mike is on the back of the camera which is itself only lipstick sized. I'm fairly happy with the picture quality, but may mount it looking backwards above the cans just to try to get a better "soundtrack," which I can then dub back into the forward-looking sequences.
