LOL - we actually have airhawk pads from the Sportie, but haven't put them on the Dyna yet. Will have to do that.

It is the sound dynamics of your pipes for sure. I just swaped out my SEII baloney side cuts (sig pic) for the SEII slash down cuts and the difference is huge. The side cuts were resonating in my helmet a lot and the slash downs don't resonate at all. Same mufflers.

Hard to believe but true.

You could always get a solo seat on ebay and one of the t-shirts that says "if you can read this the bitch fell off"

I had a similar problem after I installed Slip-ons, Stage I and SERT. My issue turned out to be hose clamp rubbing a part of the frame. However, it still not quite as smooth as stock, particularly in the foot pegs. If I took the time, I bet I could improve the vibes even more.

I wouldn't be too quick to blame the pipes. I had a 1200C last year and added Short Shots and had NO additional vibrations...until 2 weeks later when I added a Heavy Breather, PCIII and had the 1K service done. it was AT THAT MOMENT that my Sporty developed a Vibration problem. I could feel it in the Pegs and the ol' lady could feel it also.

NOW I ride an FXDL with SHORT SHOTS and added a stage 1 and notice NO additional Vibration. I asked the Ol' lady and she said THIS BIKE has not increased in vibration since the Short Shots OR Stage 1. Weird.

My 1K service is coming up and if I develop a vibration at that point I'll be PISSED!

I had a bad vibration after i installed my Bassani 2:1 Road Rage. I did not follow the tightening sequence outline or torque specs in the service manual. Over tightening these nuts can cause a big vibration issue. Proper Sequence is just as important as the correct torque.

I loosened all flange nuts. Tighten everything according to the sequence and specs in the service manual and the vibration issue seems to be much better.

Now if I can just keep the flange nuts from loosening up. I have to check them prior to each ride.

PS...Be advised Torque specs for these nuts are Inch/lbs NOT Foot/lbs.
