Are you saying all RG's have a tank slap issue? I haven't heard that before.
Wow........well after digging through the site and some reading I'm beginning to rethink a RG as a future purchase.
with the 13 and earlier road glides it was an issue when the dealer set it up wrong. Which was common as they would set it to touring bike spec, which is different than Road glide spec. I would just remind the dealer to set it to road glide spec each service, no issues when they did that.
I am the first 15 I have heard of with the issue. It was not an issue for the first 5500 miles. I tried to make it do it when I first got the bike, it would not. Bike was serviced, and part of the 5K is check the fall a way or neck bearing. They adjusted and very first ride I noticed the tank slap.
It's an issue with Harleys procedure I believe on the 15. As come out of the factory, my wife's 15 has not had tank slap, and Joes 15 CVORG has not had tank slap, they have not had 5K service, and they have not moved the bars.
