Looking To Diagnose Power Loss And Throttle Response Issues.

I've got a short video below that may better display the issue than how I could describe it. Ultimately, there's irregular moments of power loss, as though the bike is going to cut off but it only just drops it's RPMs low, as falling back down to idling RPMs. I experienced this a few times over the past few weeks.
I finally got the issue on video but it was a more dramatic issue than I had seen before. In the video, you should see, 8 seconds in, I'm attempting to open my throttle all the way and the engine is bouncing between 6,000 and 2,000 RPMs.

No idea what this could be.

2022 Street Triple RS

• >22,000 miles
• Recently replaced air filter and spark plugs (twice, after the initial onset of this issue)
• Recently started using the built-in USB to charge my phone after snaking a cable to the front (I have stopped using this to see if this could be the issue.)

Both changes above were done just before the symptoms. Could be just coincidence but thought to mention it.

Thanks in advance for any insight or direction

 

Odd one. I would suspect air or fuel mixture messing up. Perhaps needs a map adjustment.

 

Interesting suggestion. The issue is that it happens seemingly randomly. When it does happen, it seems to be when running at a consistent speed and RPM, but then won't be reproduced under the same conditions. This is what leaves me to believe it's something faulty. I'm hoping someone has seen something similar and can point to a likely component or set of components that need to be replaced/checked.

 

Has the MAP sensor been reconnected properly. Is the hose attached to the underside? It will have been disturbed when you removed the airbox.

 

(Excuse delays to my responses as they still need to be approved.)

Thank you for this suggestion.

I was certain that this was reconnected after my second spark plug replacement. But, to be sure, I just checked again. They appeared connected but I resecured them both.

I'm uncertain at this time whether or not this has made a change.

 

It might be worth checking that all of the throttle body vacuum hoses are intact and none are trapped. Have you checked for fuel starvation, vacuum in the tank. Maybe a trapped tank vent hose? If there is a component issue it's likely that the MIL light would have come on?

 

Could be worth checking the crank position sensor too.

 

I wonder what you mean by this. Or, how this could be done.

When you made your original suggestion, I reconnected all hoses routed to the gas tank and made sure they were unwound and not bound under anything else. I also made sure to secure them as deep as possible to their respective nozzles. I also reconnected the electric connectors for the fuel pump.

To be transparent, I will note that the the hose connected to the MAP sensor was not as far as it could go. I believe the MAP sensor is the sensor shown in the attached image (although this is not a diagram exactly for the model I have).

The only light I have is the "get your Triumph serviced" light. Which I begrudgingly ignore since I do my own service. (I understand that I could get rid of this with a "Dealer Tool" and possibly with TuneECU.)

As it stands now, after doing this, I took the bike out an hour-long run and did not see this issue. I'm going to take the exact ride, clipped in the video, this weekend and see how it goes. (And hopefully not get stuck 20 miles from home.)

 

I'm having some difficulty in tracking where this is exactly based on the documentation that I've found. It appears to be under or near the alternator cover on the left side. Assuming @TRIPLE X 's suggestions haven't resolved the issue, I'll take a look there. Thank you.


Aside: I do wonder if there's someway to read all of the diagnostic data and see if anything is nearing minimum/maximum thresholds.

 

Basically, are the vent lines free to vent which could show up as the tank sucking air rapidly when you open the cap after a short run.
If the tank drains i.e. the engine consumes fuel, then the tank needs to replace the volume with ambient air otherwise you will have a pressure lock and no fuel will flow out irrespective of liquid volume present

Is that now clear, ask further if not?
