Not all Connies "feel" the same.
Last year, coming back from the Spider Ride, Jon (1999) and I (2005) swapped for about an hour or so. Bikes felt completely different. Neither was really better, they were just different. The buzz was not bad on either, but as you went through the gears, you could feel the pegs and grips vibrate at different speeds between the two bikes.
Maybe it has to do with how well the pistons, rods, etc. are matched.
No complaints about mine.
One thing I'm not sure I saw in the thread was about not gripping with a death grip. I do find that if I tighten my grip, vibrations get a lot wors on hands.
