Who has a gopro

Are you using the open back or the sealed one? Where was it mounted?
Rollbar mount will give you more wind noise than anything else.
Try using the suction cup and tuck it in right next to the windshield with the open back.

I've had one for a year or two. I put it behind me in the center with the suction cup for track events. I think I had to leave the seal in and put it on LO for sound (can't remember i that is senstivity or not). I get OK sound at WOT on the track, but anything less than that, then not much sound. Wind is just too hard on them in a cobra. Now if you mount it to your door close to the pipe, it may over power the wind noise. I haven't tried that though.

I thought the new ones might have an external jack for a microphone. If so, if you can plug in mic of some sort, just lay it in the floorboard, and you'll get great sound and no wind.
