Eek R1150GS 2001 / Bad noise / video

Just returned from an hour of highway drive and this is the sound I heard when I stoped the music....
https://www.youtube.com/watch?v=bYUKfF2clwU

It sounds like it's comming from the back of the engine.

Can someone give me an idea what's wrong? (espacially if you experience the same noise)

Thanks

Fred

Sound go away when you pull the clutch? Sounds like the slave cylinder. Mine did the same. Not an expensive part, kinda a PITA to replace though

How many miles on the bike? Does the noise change when you pull in the clutch? I'm thinking slave cylinder going bad or metal-to-metal contact in the clutch.

105 000km and yes the sound stops when I pull the clutch.

I guess it's pointing toward the slave cylinder....

Check the condition of the fluid in the clutch reservoir. A lot of times when the slave is going bad it causes the fluid to cloud up.

Have you noticed a slight chagne in the engagement point of the clutch lever? That's another sign.

Sounds like the slave cylinder integral bearing.
BB has them priced well. Be sure to add grease to the little bearing, the are chronically undergreased from the factory..
Flush system with plenty of fresh DOT4

Also!

When you are doing the job....
Be sure you trim the pressure line sheath back as per this :
(the sheath holds water against the fitting crimp and will eventually rust thru)

Do I need to work forward of the cylindrical cross member or there's a way to get some loose on the clutch hose and pull back past the cross member to unscrew the fitting?

Remove the tank, cut the ty(s) that are holding the clutch line, you should be able to pull back enough to undo.
Be sure to use new crush washers or at minimum anneal the originals if you are going to re-use.
Anneal by heating with a blow torch untin the copper turns brown in colour.

It looks like the hose is stuck somewere under the battery tray.

Any advice on how to clean the slave cylinder hole? A lot of dirt inside. Any thing else I should change working in the area?

Thanks for your help GS Addict!

If there is no gear oil smell to the crud in the hole you are probably ok just replacing the slave assy. The rear seals on the trans shaft are pretty reliable. The crud will wash out with water as it dot 4 fluid based.
Use a small screwdriver wrapped with a damp rag and wipe out carefully.
