Electrical situation

Hey guys,

I had an issue a little while ago when I was riding my 919 and i had weird disturbances in my throttle response from 4k - 6k rpm's. Then at times the engine would start blubbering and the bike would shut off with the FI light on.

I brought it to a shop and they discovered that the issue was just a "relay switch" of some sort. They put in a new one and the bike ran perfect again!

Now only about 4000 miles later im having the "throttle response disturbances" happening from time to time again. EXACTLY like the time before.


Can anybody give me any advice on how I can adress this problem?

Here are some picture of what I think might be where the relay is located but if you know something please share it:

Make sure that PCIII is grounded securely to the frame or battery and that the connection to the TPS wire is soldered. I had issues with the bike stalling or not starting due to those two connections to the PCIII failing.

You can also check for any MIL codes. Check battery terminal connections and the ground connection to the frame under the tank.

Don't know what the shop did, but I don't think you got your money's worth.

This. Check AND solder all connections.

remove the pc3 and see if the problem persists....

also check the main ground on the frame under the tank.

Oh yes, I forgot to mention. They disconnected the pcIII at the shop too.


Disconnected and replaced a relay.

But I don't understand how it go bad so fast.

I gotta take a look again and see if I can find the ground under the tank.

I guess this is a good issue since I get to learn more about my bike right?
