1150gs sucking air after off? Back end of Sweden!

[Gryph]

Hi folks, looking for some know how. Video below.

Currently in the back end of Sweden doing some Tet/generral touring. Bike went over in some swampy stuff at low speed and left side managed to find the only rock. (Typical).



Looks like the crash bar took the brunt of it, but I've now got a sucking/hissing sound that I'm sure wasn't there before, and on revving the bike then feels like it stumbles returning to idle.



Has anyone run into this, or does the collective have any bright ideas?

Riding Gently for now - Feels smooth 2.5k rpm and above, rougher idle below this, and lots more backfire than normal on the overrun

Check throttle cables properly seated in throttle bodies and in mixer box under seat

Is the rubber cap still on the air takeoff point under the throttle body

Check TBS voltage

Thanks for the advice @all - got to the bottom of it while checking the above.

That'll do it! Tracked it down to the injector, crash bar had been shunted back far enough to dislodge it by pushing on the upper clip. Re-seated (easy) and crash bar brute forced back into shape (much swearing) and it's running nicely again.

All's well that ends well

Gotta the love the simplicity of these machines for repair. Glad your sorted

Thanks for reporting what the problem was - it all serves to add to the collective wisdom, for when the next person has a similar issue.
