Are you braking heavily? Or running low revs as you downshift?

sometimes it happens when in braking and in low rpm’s. i also realized i don’t know if this is all the way true or not because i haven’t put thought to it until now but whenever i put it in super motor mode it only does it but in road mode it seems perfectly normal

fuelx changes fueling in closed loop mode/part throttle/low load whereas power commander changes fueling in open loop mode/high load/full throttle conditions. They're complementary to each other and mostly wont interfere with each other.

You can stall the engine with hard braking if you misjudge your clutch control. Slipper clutch helps but doesn’t eliminate it. Supermoto mode could make this worse because it allows you to lock the rear wheel which will then stall the engine if the clutch is still partially engaged.

Try running it on super green fuel

I had this problem and it turned out to be a worn clutch switch i.e. the switch on the clutch handle.

The wear was slight - but it was just enough to screw things up. You can troubleshoot it by removing the switch so that it just dangles, and when the engine cuts out, toggle the switch a little bit.

Not saying it isn't true as I've never
1 had the problem
2 it's just an on-off switch
But an interesting approach.
How many kilometres were on your bike when the switch was warn?
