I have had my 2010 GSA since Feb this year - its got 14500km on it now, bought it with 5K on the clock. Under load the motor seems to knock as well - is this the "Pinging" that is spoken of? If i shift to a lower gear the noise is gone - only appears under load at low revs?  ???

See Schlowy's remarks above. I took a 1200GS for a ride.  Same noise but fainter than mine and goes away if you speed up. Also rode two 2009 GSA's. One the same spec as mine the other 2009 spec. Both under 20 000km on the clock. No noise.

On mine the noise is more noticeable and goes away above 3000 revs. Having it checked out on Wednesday and will give further feedback. Have the idea now that it is enjin settings.

Schlowy's comments are a bit too cryptic for me, I think you need in depth knowledge of the subject to fully understand what he is trying to say.
Look for a shooting star and see Lynda's trail and remember all the great places you shared with her,she will never forget what she shared with you and will show you that in every starry night .

Sorry guys ,this what happen when you hit your head  many times.... your think something and then write some thing else  ;)
let me try again

the issue with those motors is the mix of the fuel with air ,when it is too lean the engine start to ping i.e the chamber Temp is too high and ignite early then the engine management " plan"

the gs1200 2007 models did it more then the others ,in 2008 and 2009 GS 1200 the problem was rectify by BMW but in 2010 it's appear  that the problem come back again (at list from our clients)

the option you have (i don't try to do a sale speech here..)is to put the Accelerator Module or Booster plug which cure this issue completely or to go to BMW and let them play with it for a while . some time they can resolve it most time not ...

Would the pining then sound  like the faint knocking you get from a diesel enjin ?

chance is that your bike pinging i.e . too lean mix , from what we nether 2007 models had this issue which was "cure "by BMW in 2008/9 and then the 2010 model start is all over again ...

That would be my guess. Dont agree with the 2008/2009 statement. We had all the models on the dyno and all models were running lean at low revs.

Correct, and a Accelerator module WILL solve it - no I am not a rep for Schlowy :)

Right, done all the reading. The thingymebob looks like the starting point.

Schlowy, do you have stock of the AM ? I'll be dealing through Alan Lewwis Motorcycles in PE. Want to place order on Wednesday.

yes we have stock ....
and as mention before the 2010 models are almost as bad as the 2007 so that noise under  load is what i was referring  to ....

Talking about oilhead noises my HP2 makes an irritating ticking sounds from  the LHS pot - can be heard at idle mostly. All mechanics have listened and said tappets  - does seem to be reduced when they are set slightly on the tight side but still a mystery. Also it is not coming from the TB's. I know on the 1150's the timing chain could get noisy? Thoughts?

As I said earlier, I don't know what noises these enjins are supposed to make, but I'm learning. Each of the three 1200's I took for a ride this weekend make their own noises. Maybe then each enjin as it runs in develops its 'normal' noises, as with my Airheads. I know each one and when it starts to sound different I know it must be looked at.

Been riding a boxer for 4 years now and still not used to all it's funny noises. Spend hours worrying about stuff I hear and at the end it's just nothing to worry about. You'll get used to it. Even my brand new one has unsettling noises some times. Have it checked out but I believe it will turn out well. Ry daai ding man :thumleft:

It's not the injector ticking?

The injectors make a distinct ticking sound, to check if that is what you are hearing, at idle just put a faint tension on the throttle cable and you will hear the note of the ticking change.

Buzz this is what I had thought at one stage but as I say noise not coming from TB's (injectors on top) ... anyway bike faarks off and does not seem to affect its performanvce, but still curious.  ???

Please excuse my ignorance, but if the down side of an engine running too lean is over heating, what is the down side of an engine running too rich?

BigD, interesting - same knocking sound from my EishPee's left pod.  :3some:   :biggrin:
