Another Engine Noise Thread

I'm another owner who has an unacceptable noise coming from the engine of my 2013 R1200GS LC. I've read number of threads and watched videos describing the same noise under the same conditions.
My bike has been making the sound from about 15,000km and has gradually become louder through to the current 51,000km. It has been three times between two dealers and is now well out of warranty. The dealers' diagnosis of what it could be was only guesswork. The noise is now at a level that attracts a lot of attention from other riders.

I spent a number of years in engine machining and the related diagnostics in mechanical noises and mechanical failures. The location and the frequency of the noise makes me suspect excessive gudgeon wear.

It has reached a point that I no can longer ride the bike through fear of component damage. In the next few weeks, it will be dismantling time and I'll have to report back with pictures and details of what I find.

Is there any more details that you can add, like anything particular that may have occurred around 15,000km to the engine or what side the sound is coming from?
If it is in fact the gudgeon (wrist pin) it will be the first one that I have heard of failing on the LC motor.
If it's been run like that for a while (and apparently it has) than it is possible the damage will be extensive and require a piston assembly and jug replacement.
If it was only ran for a short time and the wrist-pin bearing is serviceable (it's not in this case) often times you can get away with fitting a new bearing and wrist-pin and being good with no need to split the case.

There has been nothing out of the ordinary to cause deterioration. The sound is coming form the left side only and is most prominent at idle when at operating temperature. There are reports of the same noise from a number of sources but I'm not aware of any reports of complete failures.

The damage is not likely extensive. My worry is having metal particulates in the oil. There should be no bore damage. The wrist pin is located with circlips in the piston so it cannot float axially to touch the bore. At this level of noise, it is likely to be the small-end bush (probably bronze composite) that needs replacing. The wrist pin, usually being case-hardened manganese steel or something similar, will tolerate a fair bit before wearing more than the bush.
To expose the piston, splitting the case is always necessary with a liquid-cooled engine; there is no other means of access.

I'm talking to the dealer again this week about my plan for a repair. It's unlikely that they will offer much assistance but it's worth a try.

Sounds like you're going to have to keep us posted, of all the noise complaints that I've heard of to this degree I have yet to read of a successful remedy.
I would be very surprised though if it ends up being the wrist-pin.
In the U.S normally a problem like this in that the bike has been taken to the dealer for repair and returned un-repaired gives the owner some ammo later if the warranty expires but the problem worsens, many dealers will cover the repair out of warranty since the problem was documented previously, hopefully that is the case down under as well.

Removing the Engine

The engine is ready for removal. Rather than drop the engine from the bottom, I lowered the whole unit to the floor and will lift the frame. That's tomorrow........

you can continue telling that to yourself to convince yourself not to upgrade . but at end, you will give in. hehe

i know many people who changed from oc to lc, and they are very happy.

remember, only people who have some issues report it here on this GLOBAL forum, most happy owners do not make posts and say WE ARE VERY HAPPY the bike is still running strong. and many other owners don't even know about this forum.


Most manufacturers, bmw, mercedes benz, all japs etc.. have some small % of cars or bikes with some issues, that does not mean the design is bad.
the machine is made by man and machines, parts are assembled by man and machines, shit happens, you will never find a design that is 100% trouble free.

i only got 6000 miles on my GSA, but those 6000 so far has been in offroad, on-road, drops on rocks, sands, water dipping etc .. and the bike is still going on strong.

I think someone should start a thread calling for the happy owners of LCs to state their MY and MILEAGE and issues reported, let's get a poll from everyone here not just hear from the unhappy ones alone

That's the first 2013 I've seen with white springs on the shocks, I'm guessing a late production 2013.
Good luck and keep us posted.

The first step in the repair

I can understand that. If it aint broke, don't fix it. I have many riding friends with the same attitude but when it's time to upgrade, I think you'll appreciate the amazing improvements in the new bike. As X7289155 described, there is bound to be a few bad apples in the mix. I could have traded the bike but I enjoy riding it so much I think that this repair is all going to be worth it.
I worked for a number of years in engine machining and diagnostics of engine manufacturing faults. I'm confident of a worthwhile outcome in the process.

It is indeed a late 2013 production bike (Australia).
