Was walking through a nearby HD dealership with a T-shirt that I'd bought for a buddy when I saw it...a brand new 2010 CVO Street Glide with a tequila sunrise paint job...it was love at first sight!!! I had to have that bike. A couple of days and many dollars later, it was mine! I live in MN and the riding season is coming to an end although it's been sunny and in the low 50s for the last week. I took the bike out for a 100 mile ride and loved every minute of it! Absolutely amazing, absolutely beautiful! Toward the end of the ride I was stopped at a stoplight waiting for the green and noticed a strange "clacking" sound that seemed to be coming from the left hand side of the engine, down near the front, behind the primary maybe. A tech listened to it and thought it might have been a problem with the self adjusting primary chain tensioner. After taking a look at it, the tech decided the tensioner was working fine and told me that he would call HD. HD told him that they are aware of the noise that quite a few of the 110 Screaming Eagles are making and that they don't quite know what it is yet. I read this thread, and saw a couple references to the "clacking" noise. Sure would appreciate feedback from others that are noticing the noise...what is it...what can be done about it...what's the deal?
