My 2021 u1000 does the same thing , about impossible to drive on rough terrain , some of it has to do with the angle the pedal is at for taller people , my wife can control it better than I as her heal is planted firmly on the floor , Also dealer says it is what it is , may be time to find a better dealer .

I bought the switch from cfmoto , like $20 and a flasher . The switch plugs right into factory wires behind dash . Wires for flasher are right under front by brake fluid canister . I'm sure cfmoto sells the correct flasher to plug into it but the one I ordered had a different style plug but does the same thing so I just used the plug that is there to cap off the wired plug ,removed the rubber inserts and added my own wire so nothing had to be cut . The wires for the rear signals are there already right next to the reverse lights and can actually be plugged into the reverse lights instead to use as turn signals ,I cut out some red reflector material and added it to the recess where the reverse lights are .The front turn signal wires are on each side in the headlight harness ,they stop at the connector so again I removed the rubber plug from the connector and added my own wire to run to a turn signal light that I added just below the headlights

Take out the 2 small rubber plugs from the connector and insert your own wires into it ,dab of silicone and done
