Nothing is broken, clam down lol. Day two of owning my R3R, I noticed what you're talking about was annoying. Fix was disable o2 sensor in TuneECU, instantly smoother on/off throttle.
What you're feeling is a mix of two things. Harsh on/off transition caused by a lean condition at 0% throttle decelerating and then crack the throttle and it then goes little rich like it should. That sudden and sharp transition from super lean during decel, to normal fuel ratio when cracking throttle is curable with fueling and timing changes.
Adding fueling in L tables at 355,424,486 columns will smooth the on/off transition of 1st, 3rd, 4th, and 5th if your O2 sensor is disabled.
The OTHER problem is 2nd gear. 2nd Gear is an *******, straight up, *******. The jerky on/off is a result of the number of dogs being 1/2 that of the other gears, so there is a lot more slack to take up in the transmission, that lash results in herky jerky feelings when in the transition point between fully off and slightly on throttle. Nothing can be done to fix this, just adapt your riding by going to 1st gear to keep RPM up slightly and avoid the stupid idiotic retarded ignorant decision by triumph to cut the number of dogs in 2nd gear in 1/2 instead of just back cut the whole trans gearing!!
