intermittant problem 650

Bikes a 2017 650 which I've had for a month, 800 miles. Problem is bike cuts out sometimes when I am standing on the pegs. Anything less than 40mph and 3000rpm , screen is totally blank with no warning lights BUT when I sit down again it automatically starts and rides normally. Battery terminals good and it only happens when I'm standing. Was at the dealer today and they couldn't see anything wrong and of course the bike behaved itself there. Anyone here had anything similar or have any ideas?
ps I'm not activating the side stand switch when I stand up

Based on your description, I'd check the wiring under the seat. I would guess some wire is either loose or getting pinched and when you stand on the pegs it is grounding or shorting.

Hey, it's not a GS. Only BMW riders are allowed to spend endless hours being Adventurous.
Peg Standing is De Rigeuer for them. They even train on perfectly smooth asphalt do be proficient at looking elegant.

The black box with lots of wires going into it which is strapped to the battery is I assume the ECU. This was sitting at a angle which could possibly be affected by up and down on the seat. I could not see any bare wires or loose connections. I'll get a ride on it tomorrow and report back. Fingers crossed.

Just a shot here...when standing you are putting much more pressure on pegs. Check the side stand switch also. Good luck!

Thanks but I tried putting down the side stand while the bike was running. The engine cut out which I assume means the switch is working and when it did the dash still had lights on.

Side stand in down position kills ignition only. Something under the seat is causing this.
There is nothing on the pegs themselves electrical other than the sidestand switch which you already
checked.

Does your bike have a charging pigtail attached to the battery terminals ? If so make sure it is not being pinched
or routed where it could be shorting out ....

No there is nothing extra connected to the battery. I bought the bike a month ago and in 2 years it had done 160 miles so its basically a new bike and I dont think a wire could have shorted out with such little use. I've moved the ECU and I'll take it a run tomorrow to try it out. It would be so much easier if the problem was there all the time.

Why do you not try standing on the pegs while the bike is idling at your home/shed? The same should occur. If not, why not? Easy if you have a main stand or swingarm stand, otherwise lean against a tree or pole.
Also confirm that it is definitely not the sidestand switch by zip tying the stand to the frame or rear footrest, or by bridging that switch.

You could also remove your seat and start the bike. If it runs, it cannot be your weight on the seat which causes the bike to run, and then to stop when your weight is removed. Somewhere an electrical connection is being disturbed.
