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.
It is not your grip. I have the same problem with my 2012 xl1200c
really annoying. It is like the bumps jar the efi.

Thanks again for all the help folks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I'd rep all of ya if we had that here.
Modular, when you say "per manual", is this the info under Throttel Control Pg. 1-67. Fig. 1-84 ? If I adjust according to manual's specifications will it fix the problem ,or is this someting not mentioned that you noticed? Any details you might provide will be appreciated.

I used the instructions in the service manual. I thought it was page 2-30.........or 1-30, crap I can't remember. I would start with doing what I did and see what that does for it.

It's your seating position, arm position and grip. When you hit a bump or dip your elbows are bending causing you to throttle up.

Maybe, but the OP said he also needed to adjust the throttle properly.

Leave the gun. Take the cannoli.

Tell me, How to adjust the throttle properly? I'm curious. If he's twisting the throttle in a dip or a bump there's no adjustment for this, it's physical. OH ya, the OP states he HAS the throttle adjusted properly. RE-READ it.

Because if the throttle and Idle cables are adjusted too tight, there's no free-play and any movement what so ever results in throttle input.....

The throttle tube is adjusted like most tings on the bike, and require a specific method to do it, with a desired result.

The correct methos is here..:

Throttle Cable Adjustment

RE-Read his post where he said how he solved his issue. He went back and found it was not correct.

Follow along, that way you won't sound like a giant *&^(. s

He explained in his his case what he found to be the problem and the solution that worked for him.
