Warranty stuff » vibrations in engine

Dear co-owners of the R1200RS, I have a problem where I like to hear your opinion and experience.
After having enjoyed driving various motorcycles for a number of years, including having driven almost 200,000 km on a number of R11000Sjes, it was time for something new last year.
At a dealer in my area there was a nice demo with less than 1000km, bought this and the first 10,000km sent without problems.
Just about after the 1st tire change, I noticed vibration. This especially while driving on the highway. After about 10 minutes, my hands start to sleep.
Furthermore, I already feel quietly 80 in with such a 3000 -3500 rpm there (for me) clearly also a vibration in the block. The vibration is also felt when you stand still and something gives you gas, say 1500 rpm, then you feel it in the steering wheel.
The engine was checked during the 10,000 km turn, the tires were re-balanced and they could not find anything else.
The dealer had no experience with the brand / type of tires I mounted and it was said that this could be a cause. Agreed that I would mount the next set of tires of a known brand and type (Michelin Road 4) and that we would then look further.
Fitted new tires a few weeks ago and had the 20,000 km service carried out. The complaint was still there and asked again to look at it. The dealer indicates that he cannot find anything that deviates. After insisting there was still a low test drive with my motorcycle, but they can not find anything strange / feel.
After the test drive I had a conversation and it was indicated that the vibrating character would be, a twin simply vibrates. This is not my experience with the R1100S, but also not the first 10,000 km with the 1200RS
After the conversation, it has now been agreed that they will request an R1200RS that is not yet registered, and then we will compare the 2 engines side by side.

I own an R1100S and an R1200RS and compared to the 1100S, the 1200RS does not vibrate, it's that much smoother.

Your problem certainly doesn't sound like it has anything to do with your tires. Perhaps there is a chassis or engine mount bolt loose somewhere?

Just about after the 1st tire change, I noticed vibration.

Tire issue probably balance.
That is what changed so put on a different set of tires.
That does not just appear, I felt a vibration since day one, just the nuance of the boxer. ( I did 1,500 miles on a '69 Electra glide ) I can tell you about vibration.

The rest is in your head.

Ride the wheels off it!

I have the same problem. Did you find the answer? :) Thanks

Sounds like something is loose or worn. Engine mount or similar is a good thought.

If happens at idle thru bars maybe check steering bearings. I know your low miles for issues there, but if grease leaked out somehow they could be binding and grinding sending vibes up bars. And or torque on upper and lower triple trees. Sounds to me something along front end of frame is loose or out of whack.

You might also try another dealership or mechanic.

I would start with the basics of the engine if these havent been checked yet; Pull the plugs for a compression check, spark plugs (probably just install new), check the coils for the correct resisstance and if that is all OK, then the cam timing should be checked, if not possibly indicated by the compression readings, injectors tested, fuel pump/pinched fuel supply hose, fuel tank vent, bad electrical ground (I assume the battery is good?) etc. Since it does it whilst on the stand I think we can rule out running gear/driveshaft.

Search youtube for Boxflyer, he has some excellent engine videos that walk you through a lot of these items

Please let us know how you get on with it and wish you the best of luck for a simple fix

Good catch! I didn't even look at the date

Sorry, did get the notivication.
The dealer could not find the problem, so I sold the bike...

Bor_S, thanks for responding. During the time you owned the bike, did the dealer ever remove the cylinder head covers or look deeper into the engine?

No he did not inspect the internals of the bike.
He did not do much. He said it were "normal" vibrations. But I am shure they where not.
After annoying myself for a long time, I sold the bike.

Too bad you never figured it out.
I was thinking, skimming down the thread, if you put it up on its center stand and then ran the motor through the gears, could it help isolating it?
Get out the stethoscope.
Oh, well.
Was a lemon that no one has yet figured out
Your dealer was top shelf!
