Not sure if it is a jet of emultion tube thing. 1st and 2nd gear under 3000rmp. When I'm driving slow behind someone. I noticed a slite unevenness in rmp or maybe slite stumble . This can cause a little bit of a jecking motions with given a little accelaration;
"Going slow in a turn under 20 mph".
Now when I'm driving shall we say a little more spirited not a problem.

I think that is normal for some people

Normal symptom. Try the -1, +2 sprocket setup in the 520 chain size. It will likely cure this symptom and give you better acceleration while only modestly limiting your top speed. Who drives these things at 120-130 anyway.

Or get a Flo Commander to even out the air jet intake. (more expensive option)
