TBW is adjustable up to 2500 with SEPRO tuner. If set 1-1 then it will be jumpy under 2500.
If the grips are loose side to side it will be jumpy.
If neither of the above apply, stop hitting the potholes.

 

Been riding for a while. I have had and do have carbureted/cabled, EFI/cabled, and TBW/EFI. Can't say I've ever felt anything alarming on any. I may be what is referred to as an aggressive rider, bike is always in the gear for power, unless straight line cruising. Maybe I subconsciously get off the throttle or even accelerate past bump. Just saying, never had any issues and have had lots of bikes.

 

I hear you. I get the same thing with mine. It's annoying, but the way it is with TBW.

 

Tsheff, that is my thoughts also. My 2011 RK has stock bars and grips. I came off a 2011 Heritage with double cabled throttle. My right hand and brain adjusted to the TBW within a couple blocks and stop lights. I don't "feel" any difference good or bad. I also ride with throttle rocker under the palm of my hand, still no issue with TBW.

 

My attempt to fix this annoying issue was to add some resistance to the throttle. I have the Kury ISO grips so I removed the throttle grip and took a piece of adhesive backed felt, 3/4 inch wide and about 4 1/2 long or just shy of the length of the grip between the actuator and switch cluster. I placed it on the UNDERSIDE of the bare handlebar where the grip goes and carefully slid the grip back on. The result is some moderate resistance friction with a silky feel to the throttle which returns to idle nicely. Tomorrow I will test it out and I feel confident this will greatly reduce the jerkiness and gear backlash on a bumpy road. Stay tuned for the results.

 

Rode nearly 200 miles today on my modified throttle grip. For me this worked great, 100% improvement and my SGS feels more like my cabled 2008 Fat Boy. No more jerking around on a bumpy road. My opinion, the MOCO should give the TBW this sort of feel, or some easy way for anyone with TBW to adjust it to their liking, like the thumb screw on older cable models.

 

I know what you are explaining I have noticed it a few times over a bad bump area , but it's no different from any other bike I had had. The iso grips made it worse they have more play in them, and the stock all black rubber ones do the same thing. The upgraded Harley grips along with some Avon grips eliminate 99 percent of the hiccups in the throttle. I personally never found it to be a problem I just observed this when I changed grips throught the years.

 

Decades ago started resting right index finger on top of brake lever to keep throttle steady. Still do it. Makes a difference to me.
