Did you figure out your vibration? Mine has developed a bad floor board vibration also. I have the BDL comp in mine, so I'm assuming it's not that.

 

I know that my 09 also has a lot of driveline slack. When I replaced a bearing on the final drive shaft, I was amazed at how much slop there was. I called one of the Harley mechanics and described it to him. He say "ya, there is a lot of slack in there...that is pretty much normal".

 

Not yet, but I'm about to tear into it. I'm not sold it's the comp because it doesn't seem to make any noise other than the normal startup bang which it's been doing since day one.

I hear ya. I was lucky to have owned a 10' for 35k miles and it didn't have the driveline slack this one just started demonstrating.
This one feels like, you know, a loose chain or something. Gas it, big pause, big bump then goes.
Then there is this vibration that is all over the place really. Bad at 2200-2500 rpm mostly. The engine is jumping around in the frame like it does at idle but at speed.

I've read a lot about vibration and comps over the last few days.
What I basically get about the vibration is that it could be exhaust touching the frame, a bad tune, something in the primary, crank runout, intake leak, spark, gas, air, or the presidents fault.
All over the place...

So today I'm going to start tearing into stuff and eliminating junk. Good times.
