09 M8 vibration within the tunnel when going on flats 35-50 mph. When climbing, or giving it WOT, no issues, just when I am running it somewhere on the flats for any duration. Almost like something is hanging up. I did have a front rail nosepiece that had busted apart, but replaced that, and no obvious signs of issues with the track.
No problems with this last year for 1000 miles. Any ideas?
