How smooth are your bikes?

Figured I'd ask this question as I have no point of reference. How would you describe the smoothness of your Vulcans? Like glass? Pretty good vibration? Like sitting in a massage chair?

I get some pretty good vibration (i.e. massage chair) while riding, just wanting to see what you all felt was normal before I go start tearing things apart.

Have you ever changed your balance dampers? It could use them. They shrink, and break down over time. If you find black plasticy bits in your oil screen, then they definitely need to be done.

Requires an engine pull. Might as well do the stator, and maybe the stator cover mod while you're in there.

An engine that is in good condition has very little vibration. You can feel a little bit at the handle bars. There is almost none at the seat.

Mines pretty smooth at most rpms. Considering its an abused 85, I was surprised. But I mounted a cam on the bars the other day, and shot thru the windshield. You can actually see the flex/vibration from the engine at diff rpms in the plexiglass (looks like youre on acid) and works like an oscilloscope. Overall though, much smoother than my Triumph and BSA, and my 68 Sportster. More vibes than my SuperGlide though.

Mine is good at most rpm. There is a rpm range where the right mirrow is a bit shakey, but the left one isn't and the right peg has a slight vib but not the left. But I don't feel anything is the seat or the bars, go figure.

Mine has quite a lot of vibration at higher RPMs. It's been that way ever since I installed the VN900 seat. That vibration has carried through both engines it's had, as well as with the temporary replacement bike that I bought. When I put the stock seat back on before selling it, the vibration was significantly less. So it would seem that in my case it's largely due to the seat mount I made.
