cool, thnx :)

Ok next time i will try to remember that I dont have a Tenere :D Can anyone clarify this procedure on XT660R? Because I cant see any pipes behind the bashplate on my XT :P
|
help anyone ? :$
and what if I remove the breather pipe from airbox and reroute it much higher, like on top of the airbox? and would use a separate filter on it... what about one-way valve in the tube? can I use one? which way would the valve have to be. when I put my finger on the pipe it felt like it is sucking air from airbox? |
Hi Piipz - as you surmised, this thread is in the Tenere specific section which is why you might not have got an answer yet - have you also tried asking this in the XTR tech section?
I am not familiar with the XTR/X set up compared to the XTZ, but what you are saying above would be an option I'm sure - a lot of dirt bikes simply vent into a small filter and/or one way valve - although if the bike pumping out a lot of oil, it might make a mess under the seat? Routing the breather into the airbox uses it as a sort of collector (and any gases/vapours get recycled into the engine), and on the Tenere there is a drain tube from the bottom of the airbox which you can empty out periodically. Hopefully some on the XTR side will be able to give you a definitive answer/solution? xxx |
had a tenere in to the workshop for some work , a 12 volt socket and a cent/stand , funny to pull up out side the garage and see another white ten , when it was up on the bench i had a look and it was full and i mean full , so drained it off just over 200ml so i put the plug back in and parked it out side on its new stand 2 hours later the owner turned up for his bike and it was 1/2 way up again the air box must have had aload in , anyway told him about it and the site so he might just turn up on here with us .

where was he from kev?

Latest news: in Germany all Yamaha dealers got a writing concerning the modification of the breather(partno.11D-E5371-10, of my '08 Tenere), which must solve the oil drain pipe problem. Which it did for the Tenere riders who had the modification exchange in Germany. So, ask your dealer for this, if it's taken care of in Germany, it must be available in other countries too, I pressume(I contacted my dealer here in Holland with this information, so he can call YamahaNL).

:mbounce:Hi Hans/Jenny
It looks like I'm finally vindicated for bring this up on the forum all that time ago and lets hope Yamaha UK do the mod also! We need that copy letter or service sheet,Hans from Yam Germany though to push the case through with UK. Thanks for the post its good news! I still drain mine at least once a week but to keep Jmo and the Guvnor happy I put the drain pipe bung back in some time ago! Thanks Mark |
Not sure what mod has been done, this part comes standard on the 2008 XT660Z. Please can we have some more info, thanks.

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

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. ToKi |

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. ToKi http://akpnog.bay.livefilestore.com/...4/breather.jpg |

Thanks mate here are the photos for you XTZ owners.

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.

hi all, i thought i was being left out of the oil draining hose thing,or maybe i didn't ride fast enough[or no oil in the engine eek].the only draining mine does is water funny enough.
with the pictures of the two bottles my 09 has the newer bottle so if you can view a new bike in the show room with the modification let the dealer know,it just proves the older was not doing its job and you want it sorted as running low of oil is not good,especially for warranty claims stoic |
Hi first post, been following this, as i ride 260miles 3 times a week, backroads, a roads and motorway. i have a black 09 ten with this mod, have only had to empty a tea spoons worth of oil from the drain pipe in the last 2500 miles, so seems to work
|
Excellent! I'll be on the phone to my dealer in the morning!
Result! xxx |
The mod breather is also available in Holland and one is ordered for mine, it'll be installed tomorrow(during the 20.000km service). Not yet figured out if it's a warranty case(probably yes), but the costs are minimal: not even 12,- bloody euro's! But hey, after that, no more oily stuff in the drain-hose!
Greetz, Hans. |
just got confirmation from my dealer: Yamaha Belgium also offer the new breather box and consider it a warranty case. You might need to ask for it yourself though as it is not an official recall.
|
Phoned my dealer yesterday who called me back after speaking to Yamaha technical, dealer needs the bike in to check something ? before ordering the part. Sounds a bit suspicious to me but going in 1st thing Mon.

I went to the my spanish dealer, and they don't even have the new ref.# in their database!!!!. They called the Yamaha factory and the answer was at least funny, no one has ordered that part yet in Spain ;) :)
The good news is that I will have the new part the next week. have fun, j. |
Took it in this morning for the dealer to check "something" on behalf of Yamaha technical, told the dealer he didn't need to mention any modifications :unibrow: . part has been ordered as Yam Tech are aware of the problem. 1/2 day to fit as they need to have the bike cold so they don't burn their dannies.
|
I have changed mine, both parts and labour were free of charge from Yamaha Spain, but I use the bike everyday and I took the part and changed it at home.
I would NOT recommend anyone to change it but themselves unless you are skilled and have a good set of tools. http://img362.imageshack.us/img362/6131/img0774.jpg Below is the new one. As a side note, the material quality of the tenere is not as good as other jap. bikes I have owned. The Minarelli engine and the italian screws require a good set of tools and IMHO they will get damaged very easily if you over tighten them. have fun, j. |
this oil in airbox drain pipe is happenin with not just yamaha but alot of the newer models from all makes

I got my breather box replaced on Friday at the same time as getting an oil change. Dealer did it under warranty and total time for both jobs was about 30 minutes. I'd given him the deails on the part numbers and he'd been able to sort the rest from there. Interesting he'd previously spoken to Yamaha about the problem and they'd not mentioned this at all to him!
Would agree this is not an easy job. Mechanic at the dealer was having problem with it as it's in a difficult to access area. Will have to give it a few days and see if i'm getting any oil collecting anymore. |
I've done about 2500km's since the new breather was installed and indeed, no more oil-residu in the drain-pipe! And during those km's I was runnin' high revs a lot(on motorways, doin' 130kmh-5000rpm), which used to fill the pipe easily! But ya might ask, where is the oil-residu now? Will it be filtered and returned to the oil tank, or straight back to the engine? What does the new breather do exactly, which the old one didn't? I think we need answers to these questions, don't ya agree?

Nerd Alert, Nerd Alert!

Basically the plastic box is a catch tank - the crankcase breathes into this, along with any oil that is blown out under pressure (as you surmise, this tends to happen at higher constant revs - ie motorway riding). The idea of the tank is that it collects the oil and allows it to drain back into the crankcase. There is another pipe that leads from the catch tank to the airbox which allows the pressurised air to flow out of the catch tank and into the airbox, where it is re-burnt in the engine. The problem (it seems) with the original design is that the pressure of the air/oil mix from the crankcase was too great to catch it all in the tank, and therefore more of the oil passed though the second hose and into the airbox. The re-design includes baffles (plates, like a maze) inside the catch tank so that the oil hits these and separates from the air-flow - the air continuing on out into the airbox, the oil reforming and returning to the crankcase down the pipe it came up - typically once the revs drop and the crankcase pressure recedes... How boring am I?! xxx |
Thanx, JMo! That's cleared now, good explantion. And you're not boring....you're experienced, well-informed, enterprising, funny, sharp, good rider etc., but not boring!! Thanx again, greetz, Hans.

One note between, the MT-03 uses the same (old design) plastic tank. Interesting to know that I did not hear about problems of these MT guys. On the other hand, some are complaining about surging.
At the end we can be happy that our big single runs that smooth, without surging and now with an 'evo' plastic tank. Hope that in other countries the exchange will be done as trouble-free as in Germany (also some dealers need a customer's hint to read their Yamaha-announcements). Gruss hombacher |

The design problem on the XTZ is that the breather box is not able to cool down the vapors long enough to make the oil come back to the crankcase, but the long hose from the breather to the air intake IS LONG ENOUGH to cool it down, and the oil goes down to the drain pipe iso being burned inside the engine. The new breather box has a longer path and is able to cool down the excess air and vapours before in reaches the airbox. Excuse my poor english, i'm spanish, have fun, j. |
Ah - another nerd! Thanks for clarifying that Jiauka - I should have been more clear that it is the air pressure inside the crankcase that needs to be released, rather than the oil itself under pressure - and as you say, some oil is carried out along with the air...

BTW: I have changed the breather too, so far so good ;) :), no more oil at the drain hose. And some side note, when an engine gets older and the piston rings have some leakage the pressure from the top of the piston at the compression and power stroke goes tru the rings and increases the air crankcase pressure a lot, but when the exhaust valves open that pressure is released back tru the rings to the combustion chamber but that air has some oil vapours, the engine "burns oil", a good breather box design minimize that issue. have fun, j. |
