Unhappy Losing power on acceleration

Greeting ladies and gentlemen,


I'm experiencing a very strange issue with my Street Triple R:
When I'm in a city riding mode (calm commute) the bike is fine.
But in case if I'm doing the long accelerate, for example entering highway, it suddenly drops the RPMs pretty hard and i'm getting all my weight to my arms. Sometimes the engine can stall after accelerating in a corner in that moment, when i switch the gear.


It looks like that (13-14 sec)
https://youtu.be/Q18-n-33Pdo

I don't switch or drop the throttle at that moment.
To me it loses the gas or spark at some point and then going on again.



I've checked the oxygen sensor (replaced with the working), didn't help. Spark plugs and coils look ok. Air filter is replaced.
What else it could be?


Thanks everyone in advance for all ideas!

Do you have a quickshifter installed?

Check the fuel hose for any kinks as you lower the tank.

Did you check your ground cables on the frame and battery?

Hmmm, i did not.
Do you think it could be a random disconnection?


The issue comes up only if i accelerate pretty hard. And only when i'm riding. I did a test in garage with wheels off the ground - no glitch.
So the bike must be loaded with some weight and accelerate harder than a city ride.

Vibration can cause loose electrical connections to lose connectivity briefly resulting in brief loss of power. I've had that happen to me and seen it happen on track, although not on a Triumph.

SOLVED!


Guys and girls, that was the battery.
It was starting up engine great, even after two weeks of standing still, but probably has lost some amp hours. Just borrowed the battery from another bike and voila - everything is fine!
