Vibration at interstate speeds -- Input please - 2012 Spyder RT Limited - 4200 miles

[BLUEKNIGHT911]

RECENT NEW VIBRATIONS

i just did 640 miles of NO smiles :cus: :gaah:, one shot, 13 hours ride from Florida to my home in SoCar....
left Stuart, FL on US95 North to US26 in SoCar to Rt.385 and home...
what i did notice is while at 70 mph with cruise control ON... when going down a grade, i felt the vibrations you speak about.... on FLAT or UP a grade, NO VIBRATIONS....

Even tho the difference is very, very slight ..... when going downhill the tension the engine is NOT exerting the same amount of force as when pulling on the belt ..... I have noticed the same thing on my 2014 RT and my Kritkit is about 160lbs , I don't have any type of damper, and I have no bad vibes ..................... Mike :thumbup:

A Vibration Damper solved that issue for me. We make one that has O rings on the roller for the 2013 and earlier also.
