Default Honda 919 (50.000 K) jerky drive

Hi there ,

It's full Spring here and enjoy riding in this season.
When excellerating in low gear and handling in lower gears I get
a severe jerkiness when grasping the throttle and releasing it.
For a long time I believed it was because of my cush drive , but since I replaced that last Sunday when getting new tires , that ruled it out.
It feels like it's coming from the small drive and the jerkiness slowly decreases when shifting up. My throttle responds because of this is horrible , and I can't seem to find the reason for it. I can a new drive chain set , not longer than a year ago , and started feeling it since then , but always expected it to go away once the cush drive was replaced. But the opposite is true and it actually seems to be a little more worse now.

The 919 has a cam chain tensioner and I wonder if that may be the reason , it has never been adjusted. Also the drive chain set I got was as followed , Honda Chain , Honda Big gear , and third party small gear, I can't but help thinking the chain drive was installed incorrectly and that the small gear might be causing the jerkiness, but i know every bike has some initial draw back when releasing the throttle , but I hear a profound clacking sound and there seems to be a half second delay before all the teeth are in sinc on the drive...

Please any thoughts from you might be encouraging , thank you

Unless maybe the chain is badly out of adjustment.......or the new chain or other parts you got are defective......or were installed wrong.
Having the rear tire/sprocket not running true can cause it too.

A quick inspection by a shop would be in order, I think.
