I have chaged grips, bars & even added the bar snake stuff in the bars with little improvement. Still during the longer trips the vibs are enough to make her hands go to sleep and with some atheritis it feels worse. Understanding the "Nature Of The Beast" that sporties do vibrate a little more than a dyna or RK with a TC or even EVO motor. I have would like to announce that I have found the cure for the 04 & later rubber mounted sporties. It seems that Harley in their infinate wisdom, spent so much money designing a rubber mounted motor sporty but then to only shoot their self in the foot by solid mounting the bar risers to the upper triple tree clamp vs the way they used to be with rubber bushings in the triple tree. Too many folks said it couldn't be done, But I did swap out the oem solid upper triple tree clamp with an 03 triple tree. And it works! The difference is like night & day. The wife's bike now feels like a dyna on steroids it is soooo smooth! Just a few parts from your dealer, ebay, and a couple extra washers the mad can be done. Attached is a PDF file I threw together with pics, sketches, & part #s. Thought I would pass this on before Harley starts selling a kit for $800. It cost me $25 for a triple tree from ebay and $20 for bushings & cup washers. Plus I made or had a couple washers laying around.
You can download a PDF file I threw together with how I did it.
