Wierd vibration
Hello to all, wondering if any of you have felt this, On my 09 Ultra, on acceleration from 3200-3500 rpms Im feeling a vibration in the footboards, above the normal, I have done some reading and some say an incorrect map may cause such a thing at certain throttle settings, the bike has the pc5, airfilter and slip ons, I dont know, any insight would be great,

I have the exact same vibration. From 3100 to 3400 ish. Driving me crazy.
I have a PCV with canned map, a/c and TH pipe. I did notice my floor board rubber isolators are shot on the right side and that is where I really feel it.

I know this is going to sound crazy but I'll say it anyway. Check your side covers, I had a similar problem on an 08 EGC and neither I or the dealer couldn't find it. I swore it was a lifter or valve. Later I messing around and found the left side cover lose at the bottom in fact it would pop out shortly after popping it in and had to be replaced. That cover would vibrate in the wind and against the bike at around 3000 rpms and drove us all nuts. Good luck!

I checked everything I could think of but found nothing loose. Then one day while I was wiggling everything and nothing stopped it, I put my foot up on the left floorboard to lean over to look at the right side and it stopped.
No wonder I couldn't hear it going down the road, it was the floorboard insert and when I had my foot on it it quit rattling. It only took me a 3 months to figure it out. lol

Mine does it and its bone stock,I just picked it up fron the dealer and they say"normal harley vibration" The bike has 7000 miles on it and it did NOT do it for the first 6000. I just went through all the mounts myself tonight and adjusted the exhaust and still the same thing. Let me know if you find the cause.

I thought my 09 Dyna had a bad vibe. I think it was because it wasn't breathing to it's full potential. I already had a screaming eagle breather, because my bike is a CVO. But it still wasn't set up for max intake/output. V&H 2n2 1 Big Radius and a Self-Learning-Module fixed it. Not a mechanic just saying it runs without the vibe now.

Allright, took the bike to the dealer for diagnosis, had them ride the bike and confirm the vibe/noise,so at this point we are all on the same page they felt what I felt. The bike has been there a week dropped it of last Wednesday, anyway they could not get to it because they said they needed to talk to the harley tech folks, So finally on Monday they spoke to them, and harley tech instructed them to put the bike on the dyno, to simulate a riding condition. Well, finally today they get it on the dyno, confirm that the vibe is there, they pull the primary cover, service dude calls me up and says, but of course, we cannot find anything wrong!!!! they retorqued the compensator, checked the chain tension, all in that area, and while on the dyno checked for frame rub or anything loose, said he was going to ride it in the morning to see if the issue is still there, how frustrating, Im starting to lose my patience with this dealer, I feel Im gettin the runaround.... I keep you all posted if and when they find a problem, if they do at all. but I need my bike weather is nice.... and Im going to ride the everliving sheet out of it till something gives...thx for letting me rant...
