has anyone that has a 2004 sportster and up with a Frankenstein kit installed noticed any more vibration after the install? The reason I ask this is in the install instructions they use black delrin bushings in the rubber isolators. To me that would seem to make the motor more ridgid in the frme which would cause vibration, also I think it might cause stress on the frame. please let me know your thoughts on this as I am about to purchase this kit
Thanks in advance
Gerald

Lots of Frankenstein info in this section.... several about sportys in particular.
