Hi all,

Since the last 10.000 km I noticed a very high oil consumption, which seems to get even higher now. I used 200ml for 400km. I have read that 1 liter per 10k is quite normal, but my Tenere does use much more.

Today we clearly saw some blue smoke coming out of the exhausts during the cold start. There is not blue smoke when the bike is warm. I am not overfilling the oil reservoir and checking it according to the manufacturing instructions (warm engine, wait 2-5 minutes and do the measurement).

The airbox is not full of oil, there was some oil in the drainage tube, but only a couple of drops. This is normal and nothing to worry about as far as I have read on the forum.
I can see some oil on the outside of the tube near the air breather (see picture), but not enough to explain the problem.

Does anyone have an idea where this oil uses come from?
I have not been driving faster than 90km/h in the last 10.000km and it is really exceptional to drive above 5000 rpm. So this could not be the problem either.


Thanks for helping out!

Jeroen

Sorry! I am quite new on this forum as you can see. I don't know how to upload fotos from my desktop and posted the thread twice

Are you sure that there are no leaks on some oil seals (gear, sprocket..)?
I would try different oil brand, before everything else. Or if you are sticking to the same oil brand for long time, then do the compression test and maybe find some endoscope. Have you checked the spark plug? On the web you can find some useful pictures for reading spark plugs.

As said try a diffrent oil... Motul 5100 or yamalube..
take the for a long ride get the motor hot & keep it hot
for a long time... could be somthing as simple as gummed
up oil rings...

A good hard ride every now and then can go a long way
to keeping the motor clean inside..

I agree try a different oil.

When I ran my XTR on Motul 5100 oil it just drank the stuff at an alarming rate.

Switched over to Halfords own and it barely touches it.

For what it�s worth, my �08 Tenere doesn�t have any oilconsumption, at 108.000km�s+; normal ridin' after warmin'up the first km's(with keepin' an eye on the oiltemp.meter) and just regular maintenance with oilchange(Yamalube/Castrol) with oilfilter.
