I think my bike is running too rich (soot on exhaust, engine better without air filter, smells of fuel). Can someone point me to a thread on how to increase the O2 on the Ten? i know there is many on the topic here but which one?Thanks.

I think you mean the CO setting? Changing the CO setting only influences the fuelling at tick-over and small throttle openings (up to 2%) it'll make very little difference. Plus increasing the CO will actually make the bike richer!

Anyhow, you can't change it on the Tenere unless you buy (or borrow) one of these...

Thanks Pleiades.
So if I get one of the diag tools it wont make any difference?? So how do I get the bike leaner properly? Can I adjust the fuel somehow? Kevs fuel mod will only make the bike richer.

Dead crow in the airbox maybe? Has fuel consumption gone up recently? Did you do anything mad when you repacked the exhaust?

Fuel injected bikes are all new to me, but I thought other than Kev's magic boxes that the ECU pretty much controlled the fuel / air mix to the prevailing condition's.
I've been looking at different air filters for Tenere's & some are designed to be 'washed & cleaned' with petrol. Perhaps yours is one hence the smell?
My exhaust also has soot in the end if that's any consolation.

Nope, stage 1 DNA filter. I blocked off the crankcase breather hose to see if the colder, fresher air improves air mixture but havent taken it for a spin yet. Will see. The fuel consumption has been heavyish for a while. 18km/l. Checked the sparkplug today and yep, black. How make it leaner?? :-(

Sorry mate but sounds like things are getting beyond the realms of my knowledge with these motors for the time being.
Maybe posting some more info, mileage, age, history, mods from standard, I'm sure the more clued up members of this community will be able to shed some light on the subject.
The spark plug on mine is black on the outer edge, darkish grey tip, & white insulator.
Is your plug completely black all over?
I hope it's a simple fix for you like your air filter was. Fingers crossed.

Yes mine looks like yours. Surely there must be a way to adjust it manually to run leaner.

The CO adjustment only adjusts the A/F ratio up to a TPS value of 18, approx 1 to 2% of throttle opening, after that the fuel injection runs on a map & ignores the CO adjustment.

What pipes are you running STD with Kat or open pipes no Kat?

Hey Kev,
