I've noticed a vibration in my '97 FXDL just under 2k rpm - right around 1800-1900 or so, and it happens if I'm slowly accelerating through that range or coasting down.It's not a bad vibe or shudder, just very noticable considering how smooth the engine is throughout the rest of the power band. I first thought it might be a loose top motor mount, but the guy in the service dept at thedealer said it's normal. It exists between 1600-1900 rpm or so - is this typical ofEvos? I'm guessing the counterbalanced TC88/96 softail motors don't have this issue?

 

I think any rubbermount has a "resonant frequency" that seems to vibe little more. My 2005 TC88 Low Rider seems to be most noticable around 2200-2500. I have a friend with a 1998 WG that says his does the same thing.
