Could it be the springs in the forks, especially if you upgraded to progressive? They give a great ride but they tend to rattle on rough surfaces. I thought I was getting static in my stero system until I turned the tunes off and the noise was still there....traced it to the forks, but the sound travels and is very hard to tell from whence it comes
Thanks, the forks are stock w/22k miles, doesn't sound like much, but it's been a few long trips. I read everything on the suggested site and will sure use that as a guide. Thanks again
