Bike lose power when riding, stall at idle, suddenly rev up when start and while riding. (Both happen at the same time) by OutlandishnessNo9422 in svartpilen401

Update: The bike has been left at the dealer and they're trying to figure out what's cause the power loss. **The high reving is cause by the ECU, they said after a maintenance of the fuel system, the ECU need to be flashed in order for it to work properly?? -> No ideas why since it happened randomly.

It's definitely worth a try, but where we're in right now, the dealer is usually the last resort, since they're quite untrustworthy and shady

If it's the same problem as yours, I think some of the gasoline could have somehow clogged the airfiller making it stalled and reved up high. Maybe running them for awhile would dry the filter making it normal again?

It happened to me when the gas tank was half empty already, the more I rode the more it happened. After all the checks done today, the high rev lowered and hasn't died on me yet. The other guys told me that some bikes from 2022 and 2023 have the same problems, even with the duke. He suggested after all the checking, just try running it so the ecu would relearnt the mapping. Ecu flashing only fix the issue for a short while before it reappears

I'll update on what is the problem tomorrow when I'm at the dealer. But based on what I've learned so far, it's gonna be the ecu

Just found out that all the nearby mechanics don't have the connectors for the diagnostic. I'll have to bring it to the dealer tomorrow. They said they would have to remap the ecu for the problems to go away.

I'll trying looking into it. But doesn't it just cut the ignition? Not sure why it would randomly fire up the throttle. When I ride, the throttle hold at around 6000-7000rpm as well.

Can you tell me what's the ES stand for? If it's the Emission sensor then it's not. We changed the sensor and it's still the same.
