it does, but is he not referring to a modification of that part?

Not to sure what you mean. I read it as they have modified the oil breather canester & I am asking for more information. These are his words below


Latest news: in Germany all Yamaha dealers got a writing concerning the modification of the breather(partno.11D-E5371-10.

Hi,
my breather was changed 10 days ago.
My dealer told me that the new one has something like a "snail drain" inside (do you know what i mean ?)
This drain let the oil flow back to the engine.
The new breather looks like the old one. There is no difference visible from the outside.
I have tested the new one last week ~3800km on my trip Berlin - Tende - Berlin. It works !
There is no oil anymore in the drain from the airbox.

I have just found that Yamaha list 2 different part numbers for the same part. The new number must be the modded part, old part number below.

Thanks for the info ToKi.

I have to correct myself !

There is a difference !

The new breather has 4 cavitys.
2 on the front side and 2 on the bottom side.

You can see and feel these.

See the attached pic.

I rang Yamaha UK and spoke to a contact I have and they said they will change the oil expansion breather box on any problem Teneres that owners highlight to their dealer. In effect this is only for those bikes that get ridden at high speeds which seems to cause the oil drain pipe to fill up quickly. It is not a blanket re-call modification! You have to request your dealer to change it under warranty!

According to my source the new expansion-breather box helps the problem by reducing the amount of oil blown back into the air box but wont cure it altogether!

To be honest I have got used to draining the tube down now and don't find it a major headache but I will get it done when i next visit my dealer.

cheers

Called my dealer and enquired about this. He was not aware of it but have given him the details and part number and he is going to get back to me.
