There have been many comments on this site about rattles and annoying vibrations affecting the 1200GS.

I ride into London every day, all year round and change my bike every 3 years (35-40k miles) and felt that my 1150GS
was the best bike I have ever ridden in my over 30 years! of riding. So it was with fingers crossed that I put an order in for one of the first new 1200's.

First impressions were mixed, It had all the good things -lighter, more power, faster handling, great breaks, etc etc. I would say It is better, in almost every respect than the 1150 BUT I was struggling to bond with it!

One of the things that was beginning to bug me was that it Just didn't sound right, in fact some days it sounded like a bloody London Taxi especially at low revs when labored. The sound seemed to come from deep down under the tank, almost like the rumble of shot big ends. the sound made the bike feel flimsy. and was affecting my whole impression of the bike.

I read how other riders had traced vibrations to the pivot brackets that hold the screen above the headlight, I could not imagine that the problem affecting my bike was coming from this part, but anything was worth trying. I took the advice of two separate links, wrapped some plumbers PTFE tape around the stubs of the front screen brackets to make them a tight fit in the the pivet holes, and slid a rubber O ring up the stub of each to cushion any left right movement of the screen when it was refitted.

It is hard to explain the extent this simple mod has transformed the bike, And more importantly the way I feel about it. 4000k miles on the clock now and the thing Just gets better and better. all traces of the "death rattle have vanished the engine is getting smoother and punchier every day in the early days There was the time when I was seresly thinking of giving the thing back...now I look forward to every days ride just like I did with my old GS.

It is Quite amassing how such a simple fault can affect the "feel" of the whole bike, but I given that a lot about motorcycling is in felt in the heart not the head maybe its not so strange!
 
Quite agree with you about the rattle. However, try using heat shrink electrical insulator. It is more resilient than PTFE tape and the diameter is more consistent.
 
My 12 came new with modified screen screws in mid Oct.

I'm not sure whether it is a new BWM mod or maybe Ocean (Plymouth) felt sorry for me and fitted some spare Touratech ones?

Anyway there's nil vibration or rattling, unlike the test bike I rode.
 
I had the same problem with mine. I cured it by fitting the smallest size cable ties around each of the stubs.

This stops the vibration, however, I wonder if the screen supposed to be able to move from side to side ..... I've heard of the screen cracking from the mount here and wonder if preventing the movement will cause cracking to propagate?
 
Mines the same...

funnily enough the vibration started just after I took the tank side panel off to put an oil cooler gaurd on and I was convinced the panels were where the vibration was coming from. I have ridden whilst holding the screen which confirms this is the source of that most annoying noise and hopefully this thread will motivate me to do something about it.

I know what you mean whan you say that you just "can't bond with it" as I feel the same way. I went into Clarks in Aberdeen at the weekend where they have an immaculate 1150 in Mandarin and sitting on it made me wantt to change back to the older model -just can't explain why. I'll fix the screen and make a decision.

HAve Fun

You dont say how long you have had your bike But my advise is stick with it.
I did so much sole searching with mine- This may sound slushy but I do think I was grieving for my 1150, But as the miles have notched up on the new bike it really is transforming and this is not me just becoming used to it. My bike has suffered the much posted fuel pump failure but my 1150 had a rear transmission
fault (rectified promptly under warranty also) the engine is becoming stronger and stronger by the day, and uses so little oil I no longer bother to note the oil consumption. something I seemed to have to do over all of the 1150's 35k miles the grunt in 5th and 6th on the 1200 still continuos to impress. however I have a sneaky suspicion that the power is electronically restricted in 1st under 15 - 20 mph. anybody else have the same suspicions?
 
There's no doubt in my mind that modifying the screen mounting pegs to eliminate the rattle, transformed my perception of the 1200.
The other thing that has made a notable change to my riding enjoyment was adjusting the handlebar position. It obviously depends on how the bars were origionally adjusted, but for me they were too far forward and felt awkward. I brought them back which now feels far more comfortable.

Any chance of a picture, please?

It would be interesting to see this in context.
 
Re picture

haven't got my camera at home, but the parts in question are fairly evident,

If you undo the two small bolts that hold the screen on at the front (right above the headlight unit) the small black parts that the bolts screw into will pall out sideways from each side of the silver bracket (that forms part of sub-frame that holds the headlight and instrument cluster). the black parts are designed to rotate in the sub-frame allowing the screen to hinge forward and backward for adjustment.

Hope this helps
