No-no-no not back to that extremely lumpy, jerky surging thing that was before I added the Kev mods. I rather walk than that.

Listen - I had no problem getting 70 mpg (imperial) when loaded up and running 15/48 sprockets when I started this trip and not thinking about saving fuel. Now with 15/47 I can barely get 55 mpg riding slooowly and in fuel saving modus all the time. So dont come telling me that everything is ok with the bike

Btw its runnig very hot too, fan is on immediately when stopping at traffic lights. Something that hardly happend before - and most people would think is because its running lean.

Said it before and will repeat it - there nothing, absolutely nothing logic with this bike.

Can you run a disgnostic tool on the Tenere? I have had the bike at a Yamaha dealer (in Australia) and they couldt connect it to any of their computers. On the XTR and the XTX it is possible, but not on the Tenere. Thats what In told both from the Yamaha dealer and from the forums.

This is the link to the tool:

It is a Yamaha service tool, not aftermarket; dealer in Oz was probably too tight to pony up for one...

Tire pressures and chain condition/adjustment can also roger your fuel consumption....as can third world gasoline...but I agree, if the fan is frequently on there might be another problem...

I don't think everything is OK with your bike, it's drinking oil and overheating, but it is hard to say the fuel consumption is bad when it has a mod that increases fuel air ratio and different gearing to stock (and even from when you started your trip).

Presumably it has coolant, a new air filter and right spark plug? What does the plug look like? White, black or light brown?

My first F650 was only troubled by wiring loom issues. The second one ate a VR then a water pump then destroyed the cylinder head due to overheating. The paint fell off the engine. All badge and no substance IMHO, although if they want you to get hooked on the brand you have to wonder why they thought a **** Aprillia would do the trick.

I failed to break an XT600e although the exhaust rotted and you did have to top up the oil between services.

I vote Yamaha, but there is no right answer. Time is more important. You need enough to find out what needs doing on your exact bike.

Sorry to TS - this has been too much about my personal bike...

First of all - bike was rebuild 5000 kms ago, and before that it was drinking oil as of 800-1000 ml pr 1000 kms. Now after the rebuild I changed oil after 2000 kms as a run in precedure and after that I have had to top up 0,5 litres. Still dont know exactly how much it uses. But it shouldnt use any oil at all after a rebuild with mostly new parts...?
The fuel consumption issue started 80 k kms back. I have been through 5-6 sets of tyres and 3-4 sets of sprockets/chain on that time so I can assure its not about that. Wheel alignment tested, exhaust tested, injector/throttle body cleaned (was very dirty but didnt have any impact on fuel consumption) tried without the O2 Kev mod, replaced O2 Kev mod - nothing have helped!

First I did when I bought the bike was getting both Kev mods and DNA airfilter, bike had Leo Vince pipes. So those have been on all the time.

Cripes, i wouldn't have waisted all my money on all those rebuilds:oops2:
It would have been cheaper, to put a secondhand lump in it. Low miler. Job done.
Don't throw anymore money at that engine SB.
It is ready for the skip?c?

If I have been able to see into the future I wouldnt have bought this huge f***** peace of utter shit at all! But such is life - you got to stick with your choice. I have had other bikes rebuild and oil consumption was zero after the rebuild, like new. But not so with the Tenere. Oil consumption is approx 250-300 ml pr 1000 kms. Ridden slowly at max 95 km/h. Less than 10000 kms after rebuild. Fuel consumption is as before the rebuild, shitty!

I have for sure thought about getting tid of the Tenere and buy another bike. But it isnt easy to get rid of a bad functioning bike on another continent. And buying a bike from another traveller isnt that easy either. Documents, insurance, bordercrossings etc etc...

What does the spark plug look like?

Yeah but no but SB. Obviously your engine is had it. Rebuilt engines are never as good as the original. Replacement engine about £400. With 10k miles on it. Should be ok for another 40k miles. Gvfm. Job done.
I feel for you.
I hope you get sorted

You didnt quite get it, did you?

First of all - A replacement engine, second hand engine, used engine - you never ever know what you get. You might be lucky and get a decent one and you might be unlucky and get a even worse one that you have. Have heard several stories about that...

Secondly - Im in south-America now, to be more precis BRAZIL. Do you know ANYTHING about this country and this continent? For example here in Brazil its totally illegal to import any used vehicle part whatsoever. To pay for a second hand engine, inclusive expensive shipping here - just to get the engine confiscated by the Customs which they do always when it comes to used vehicle parts. That is what you suggest me to do? Smart, really really smart....

They make the Tenere here in Brasil too, maybe get a used engine here? According to my brasilian friends at least 90 % of all used vehicle parts for sale here in Brasil are stolen. And first of all I wouldnt support that kind of thing, secondly I would be in big trouble if I buy and mount an engine from a stolen bike when at crossing any border where they might check the engine number. Or any other border they might check engine number.

Send the engine to another country in south-America you said? Well let me tell you this little story. Last year in Santiago Chile, the probably most «civilised» and organised country in south-America I ordered 3 spare parts from the main Yamaha dealer there. It will be here in 15 days the Yamaha dealer said. After +30 days a packet arrived from Europe, but «sorry sir, your spare parts didnt arrive, we must reorder them» **** you, get lost, Im ordering the spare parts myself I said, and did so. After another 3-4 weeks of waiting my parts were delivered to the wrong adress in Santiago because the company that I have ordered the parts from made an error about the adress and the chilean postal service returned the spare parts to Europe despite endless telephone calls and promises that they would deliver the parts to the correct adress. So I had to go back to the Yamaha dealer in again with a very low tail and ask them to reorder my parts. Which they did, but only on 1 out of 3 parts arrived after another month of waiting. So 3 months of waiting and only 1 out of 3 parts arrived.

With this in mind - would you order anything at all from Europe to south-America? Remember very high taxes, very high shipping costs and as I have mentioned you never ever know what you will get buying a used engine. And that is if it ever arrive here....

If I were in Europe, yes I might have done that. Or I might have put the bike on fire. The latter seem the better option. But I am not in Europe now as I have mentioned several times in the last few postings...I will stick with it a bit more. I dont give up that easily despite some :rain:

It looks completely normal to me. But then again Im not a mechanically skilled person....

Oh deardoh

OK, try again.

What color is the plug electrode -- White, light brown or black?

Is it oily?

Light brown, maybe “offwhite” is a better description. Not oily or wet...
