Hey all, I just got a used 2020 390 Duke a few days ago...now I have to face the Covid19 messed up NJDVM to register it! Rode it once (on a private closed road of course), and absolutely love it. I have a Grom also...very glad to be here!

Hi all.
New here and new to the world of KTM’s.
been riding R1’s for the last 20 years, due to health issues have opted for something smaller and more comfortable. Only 50 miles in but so far so good

I got a 2019 390 in July.
Great bike. It rips below 120km
The lurching below 4000 was disturbing though. I got a Powertronic which made bike into a race track worthy bike, however lurching was still there. I added a bung and an AME wide band gauge.
I then added 5-20% fuel at 2500 to 4000 rpm, up to 20% load.
As long as I modulate throttle every 5 seconds or so, lurching is gone !

I added a potentiometer as a voltage reducer to o2 sensor; Works perfectly.
I can adjust closed loop afr while riding. The low speed jerking is completely gone at 13.5 afr.
