Keep in mind even a new bike ran on a stand will have the rear wheel judder and bounce. This is because there is no load on it to even put the engine pulses and chain slop.

Good point.

Just because I'm paranoid, it doesn't mean the whole world isn't out to get me.
Words mean things.

My life is not without meaning. I can be held up as a bad example.

I think the OP is saying it happens when he's in traffic, too.

My bike ran a little rough at idle until and I used to think it went away while riding but if i held the throttle steady in motion, I noticed it still persisted. I did a throttle body synch and it helped significantly. You should look into it. It's a maintenance item.

Understood. Iím just explain why he was experiencing it on a stand. There are literally hundreds of potential causes. That is why I havenít gone further. The first real step is to go to a dealer and let someone else ride it to verify the issue is actually real and not something the rider has found a way to cause by accident.
