The very short cable for the temperature sensor

I was actually looking at getting the cable back and out to a side, but couldn't figure out a way - Probably just need better lighting. Did not take the bike onto the workbench but just stayed in the garage...

I'll ride with the O2 for now, and have a look when it get winter (I don't have insurance for the 3 winter months, so will not be commuting on it then - plenty of time to get to now the inners of the new ride. ) I have not adjusted the co either ...

Fitted a mysterious black box to my bike today ... it was dark already, ended up zip tied to the radiator hose ... not a good place me thinks

Anyway with some nice brothel illumination on, off I went for a ride.

It works... bike is smoother and less of a donkey when you shut the throttle.
Weirdly first thing I noticed was different sound when opened up from low revs. Chugga chugga happens now a good 400rpm lower throughout the gears. It pulls from 2000rpm in third instead of trying to throw the rider out of the saddle.

Looks like my 14t sprocket will collect dust for some more time.

thanks Kev .. sweet mod

Thanks for the feedback, you got all the areas covered, smoother ride, can ride at lower RPMs & the bike should pull better from the lower rev ranges, you should have better on/off/on throttle control.

Try doing my twist grip mod as well this will allow for great throttle precision in the tight stuff.

Snap I also attached mine to the hose as I was thinking of excessive vibes from the fan mounting position. It also pushes the cables down towards the exhaust.

So does it work? Yes. Bike is a little better all round. Bit smoother in lower reaches of the rev range. Just seems to fuel better. Sometimes the stock bike feels like (and does) stall in low gears if revs are too low ie trying to pull away in second by mistake. For some reason it also seems to be smoother when cruising into work at 75 mph. I was worried about fuel consumption but first tank returned 65 mpg.
So all good (have to now admit I bought it secondhand on this forum) .

Nice results John thanks for sharing. Can you put strip of foam or rubber insulation between the mod & the hose just to keep the plastic box off the hose not to sure how the LED will take that heat.

That's exactly what I found. Had a 14T sprocket on for all of about 500 miles, fitted the O2 controller and when straight back to 15.

With the O2 controller you benefit from the longer legs of the 15T, yet get the same ability to pull smoothly from low speeds that you'd get on a stock-fuelled bike with a 14T. Best of both worlds! :023:

Found a side affect tonight coming back home from visiting my sister. Tank was low & Mrs on the back. Filtered up between cars and waited for lights to change. Lights orange and car to left guns it so I do the same - and pull a massive wheelie away from the light scaring my wife half to death! :)

That's funny.

Just wanted to ask you guys would you prefer a green LED or stay with the red or remove the LED totally like Dynojet have done on their O2 Optimizer? Only problem with removing the LED is it is part of a diagnostic's for the O2 controller.

KTM forum wants a Green LED.

Don't think the color matters - would have thought the ktm guys wanted it in orange :-)

All smiles - Kev's O2 Controller on the T�n�r�
 

Out of interest, what does the LED actually indicate? Does it simply show the controller is powered-up, or does it indicate a communication link between ECU and the O2 sensor?

I'm also surprised the KTM lot don't want orange LEDs. I thought they liked everything orange, right down to the wife's lingerie! ;)
