Excess oil in the breather.
 

With around 27,000 miles on the clock the Ten seems to be getting worse at pumping oil out of the breather. The mechanic on our trip seemed to think that the reed valve on the air induction system may have got dirty and therefore allowing execs pressure to build in the crankcase.

Does anyone have any experience with this?

For a further explanation go to section 7-11 of the manual

Cheers

My 08 Tenere use to blow oil into the airbox quite badly, Was always taking the bung out of the tube to drain the oil from the pipe.

Got the 09 Part (catch tank between the air box and engine) fitted under warranty and the problem has gone..

same here !

Please explain more,
1)how or who determined it was a warranty repair ?
2) How did you identify that this part was the problem ?
2) Is the 09 part different ?
3) To make sure we are talking about the same part what part no are you referring to .

Thanks in advance
Scott

I don't know who initiated the warranty replacement, there has been no recall, BUT there have been several people on here, including me, that have had it replaced under warranty.
The parts look different as well, the 09 breather has three (I think) snail shaped chambers formed into the breather.
It works.

I complained bitterly about this whilst my bike was in for the 'problem' but as the mechanic said it wasn't a problem they would not update to the new breather . I will have to buy one myself ! Stuff Yam UK, they are not consistent in their decisions and will not acknowledge any of the problems. Not one item that has failed has been a Warrenty recall, we the users have had to do all of the work ourselves despite items such as the cush drive ribbers, engine breather and reg / rectifier not being up to the job.

I went to my dealer with the two part numbers and some printouts of the pics from the original thread. I explained that I was having a problem with the breather pipe and that the new part on the 09 model fixed the problem. Dealer promptly checked and ordered the part and replaced it free of charge under warranty.

Yep, that was me who initiated this thang! As said, I contacted my dealer and he ordered the �09 part and replaced it under warranty, no sweat! And indeed, the problem of the always filled tube has gone. Mine was replaced at 18.000km�s(june �09) and now at 27.000km�s(november '09) still workin� fine! Ya just gotta ask yer dealer and he must deliver, if he's a good one.
