Odd fueling issue today

Rode yesterday....290 miles..no issues... Today went for a shortish 100 mile ride..Right from the start something wasn't quite right... Pulled away from my garage and the bike kinda stumbled...like it was cold.... I thought Hmm..Odd never done that before but didn't think beyond that....The bike did the same all day...I gassed up thinking it might be bad gas...same issue....Its as you pull away in 1st..it pulls normally and then it kinda dies/stumbles for a second and then picks up again.... I tried different maps...same issue.... Anyone had this issue?? Its like a bad fueling problem... I wonder if having the dealer do a TPS reset will cure it...Bike runs no problem otherwise...no pick up issues at all once under way......

Sounds like bad gas or maybe something with the fuel filter. I got bad gas once and it would cause it to stumble only at certain rpm ranges.

I had similar symptoms when it was very humid out. Air quality was very poor..
Seemed to go away when the dew point went down...

I had a similar problem, I thought the fueling was bad but then i thought it felt more like traction control kept kicking in but No TC Light. I took off the rear speed sensor and there was a lot of crap on it from the exhaust from the flames/smoke. It was just enough crap where the magnetic sensor did not sense/pick up all of the spacing/timing of the rear wheel sensor ring which causes the TC to intervene . Cleaned it and the problem went away I also notice the throttle control was smoother much less surging. Now I clean the sensor every time I clean my bike/wheels it takes 2 min. and a 8mm socket. I don't know if this is your problem but it doesn't hurt to try it.

BTW I took it to Ducati and they were stumped they tried a lot of different things and finally scheduled me to bring it in to tear the engine apart the following week. Glad I decided to Troubleshoot it myself. Told the mech there and now that is the first thing they will check when/if other bikes has this symptom.

ScrapperX, what are you cleaning it with? Just a damp cloth?
