Just dawned on me that the bike in question is an Ultra Classic with cruise control. There is a procedure listed in the service manual for "cable lash initialization" that might cure the problem. It's a simple do it yourself procedure using the cruise control switches.

It's interesting to me since I actually work on Harleys and have been doing it for years but do not profess to know much, especially since the TBW system came out but I do know how they work, just not see one or worked on one but since someone said they were not an adjustment on the cables for the TSD's bike I assumed he knew what he was talking about. What a joke. My old long time friend brought his 38 over.. Never drove one or worked on one but too my amazement it did not have a return spring on throttle and only one pull cable which worked both as the push and the pull.. but no return spring. Got to talking to my friend about the newer system that had taken the adjustment out of the cable. He looked at me and symple said, "What are you talking about." I said, "You know, the one a few yeasr after the 04 but before TBY and he just laughed. Made me think and so I went looking...This is in my latest manual I have for the 08. Interesting were others get their info. TSD, if you throttle on the bar looks like this and your interested PM me and I will send you the adjustment procedure.

Ripsaw if you are referring to one of my posts maybe I did not make myself clear (not the first time). I said or meant to say that the throttle and idle cables are adjusted at the handlebar where the cables exit the switch housing but there is no adjustment of the cables at the throttle body.
I think TSD is referring to the throttle grip turning a small amount before engaging. Not the in and out play between the grip and the switch housing.
I may be wrong.
If you know the procedure for removing excess throttle rotation after the cables are properly adjusted as specified in the service manual please post it as I don't know that. Thanks.

Depends on if its FI like mine or carb. Assumed FP was talking FI but could not beat a answer out of him, sort of up or down in or out. Ha. The TBI expert was the post that I assume was referring to no adjustment and he may just have been referring to TBI alone. Actually the complexity of most of the issues and some of the crazy responses make the issue loose any credibility here anyway.

It's an 07, it's fuel injected.
For non-cruise equipped bikes, the adjustment process for throttle and idle cables is simple:
You need to remove your air cleaner so you can access the throttle wheel on the fuel induction module.
Pull back the rubber boots, and loosen the jam nuts. Back the adjusters out all the way (full slack) on both cables. With the handlebars straight ahead, turn the grip to open the throttle all the way, and hold it open. Then turn the cable adjuster to take the slack out of the cable, and until the throttle wheel (on the throttle body) just hits the stop. Add another turn to the adjuster, and lock it down with the jam nut.
Then turn your bars all the way to the right, and take the slack out of the idle cable with the adjuster. What you want is for the cable housing to just contact the spring that's inside the cable guide on the throttle body housing. If the throttle returns to idle smoothly, tighten the jam nut down. You can play around with the adjuster a turn or so either way to get the best response. Cover the adjusters with the boots, reinstall the air cleaner and go for a ride.
For a cruise equipped bike, the adjustment for the throttle cable is the same, but adjusting the idle cable is a little more complicated. You need to hook up an ohmmeter to the cruise cutoff switch on the idle cable, and test the continuity at different handlebar postions, rolling the throttle on and off. I don't have my service manual with me, and don't remember this procedure off the top of my head. Maybe someone who's recently swapped cables on a cruise equipped, cable throttle bike can chime in.

If your out of adjustment.
I think I would start by checking the cables are actully in the groove on the grip.
I was doing a service on mine and while looking things over the throotle cable came out of the recess on the Thottle body and frayed it..
Replaced it (both)
The adjustment was very easy. again out of adj.? check the grip
