Just rode home from mid sussex early this morning and on start up the exaust flap was making an odd noise like it was trying to reset. Rode it anyway with my lad on the back,seemed less power and no popping and banging on the overrun:confused: Got it home ,stoped it then started ,flap quiet ,but still seems down on power,anyone had this? Is there a reset procedure or is it a dealer trip? I ask here as the dealer is not open yet:D:beerjug:
 
So what if....

You're in the middle of nowhere (or at least out of reach of BuMW assist) and this valve carks it (whether it be open or closed)?

Will the ECU have a huff and deny you further progress (one would hope not)?
Will it blunt performance and / or damage the bike if you carry on regardless?
Can you manually open or close it (depending on what position it failed in) and leave it there until you can seek assistance from a nice man in BMW overalls?

It just seems a bloody stupid thing to put on an 'adventure bike' especially as it's stuck underneath the engine and is gong to cop for all the worst of the elements / water / road salt etc.

Edit: I should say, I'm not knocking 1200's or indeed the new twincam - I had a ride of one and it was great.

It will run even if the valve is stuck or not reacting apparently. I noticed a blunting of performance for the 30 miles or so it took to reset but that may be because it had me and my son on it!!:augie .The performance was like my old SE so not that far off normal but noticable since riding the new twin cam.I had the same reservations about it but they used them on Yam Exups years ago and its a servicable item.I dont think you can totally remove it without performance being affected but then I'm a Doc not a BMW service engineer:augie Surfice to say its ok having done nothing to it:thumb2

Usual 1100/1150 reaction to progress. :D:D
 
Does anyone know the "parked" position of the valve?

I had the can off my RT recently to change the rear tyre and was a bit surprised that with the ignition off, the valve sat almost but not completely parallel to the airflow. It looked as though it wasn't quite right and should be adjusted.

Anyone seen the same? thanks, Mark
 
When the bike is at idle the valve is slightly closed and stays in that position when you turn the ignition off.

When you turn the ignition back on the valve is cycled from fully closed to fully open and stays in the fully open

position until you start the engine and then it closes a little again.

Video link to the valve moving on startup.
