Angry Jumpy throttle over bumps

This is my first Harley that has had this problem. On streets/freeways that are not in the best condition or have bumps as I hit them it makes me crack/bump the throttle. This has become worse since installing drag bars using the stock C curved riser but was there to a lesser degree with the stock bars. I have the throttle cables adjusted correctly, I'm not leaning on the bars nor white knuckling the grips. This is getting very frustrating and I am at a loss of what to do next.

Any thoughts? Bike in question is a 2012 XL1200C I bought new.

Yeah, did that. I've done everything from letting the grip float in my hand to a tight drip to hold it steady to holding it with 2 fingertips. Again, this is the only Harley that has done this.

Huh... It's a 2012? If so warranty maybe, at least have dealer look at it.

Like what he said - relax. Could be this is the first Harley you've had with a properly lubricated throttle cable so it moves easier (or maybe it's a fly-by-wire). If it's really a problem try tightening the friction control a tad so there's more resistance. Be careful though, you still need the throttle to close all by itself!

I don't think this is an issue with my grip as I have tried every different grip I could think of to see if it went away. This is a Sporty so it's got cables. I have had an Iron (bought new), XR1200 (bought new) and a Street Rod and non of them did this. The '03 SV1KS I had never did this, nor did my '77 GS750. First bike to ever have this issue.

Modular,,
I'm going out onna limb here,,,off the wall thoughts...

Go for another gear,,

Get your riding position looked at, re-evaluated, Are your elbows bent ?
Straight arms will do that.....

I bounced over some bone shakers at various speeds n throttle positions...
Only time I can remember that happening Is when I gripped hard....

They said at HD everything was normal huh,,,
Sorry But trust Is earned, not given...
My next step would be,,,
Get the HD service book and take the whole throttle rig apart,
Inspect It myself for cable defects, binding, Improper routing....

My 2008 1200R throttle feels just like the Dyna I test rode,
and my buddies 2007 1200C,,,

Yeah bran spankin new bike and you've been on other Harleys,,,I'd take It apart.

After checking everything I'd bet the new bars are causing It,,ya may need different length cables....

I had the throttle apart last weekend. All is good there. My arms have a bend to them with no pressure on my hands.

As far as cables go....I went a little lower to drag bars but none of the control cables are out of shape. It also did it with the stock bars but to a lesser degree. This is gonna suck if it's the bars causing this.........

By spring, you mean on the throttle body for the push cable?
