Kev Mod and O2 Controller Arrived.
My Kev Mod and O2 controller has arrived - 5 days from Oz to UK. Amazing ! Will be fitting over the next few days and will report back the experience. I already bought and fitted the stage 3 side filter and DNA stock filter and replacement but didnt order the snorkel cover mod. Cant ride without it so am ordering from BK today.

Just like to add my thumbs up. To anyone that is debating whether to get the O2 controller, take it from me it is money well spent. First ride after fitting was a dream, it really is like riding a different bike in traffic, no struggling in the low revs and it pulls cleanly all the way through.
Thanks Kev for the time and effort that you and others have put into these mods. Cheers Glenn |
Thanks for your feedback Glenn glad you are happy with the results.:blob5:

After fitting the O2 controller back at the end of February, I initially suspected that the fuel consumption had improved somewhat. It was difficult to assess exactly though as I hadn't been through enough tanks of petrol. Now we're six months down the line I've got a better picture of just how much more economical it is.
Before I was averaging 57mpg (5L/100Km). During the last six moths I've been averaging just over 60mpg (4.7L/100Km). The Fuelly consumption graph makes the difference plain to see... http://i864.photobucket.com/albums/a...psbb8810fb.jpg The O2 controller obviously makes the closed loop fuelling more rich than stock, which you'd think would mean less mpg. However, the fact you can use higher gears at lower revs, together with the motor being more efficient and silkier on/off the throttle, means you can ride much more smoothly, hence the improved mpg. Well that's what I reckon anyway! Note: The big double spike in mpg in May (for those that are interested) corresponds to the journey to and from the Lakes Meet. The weather was so sh1t, cold, wet and windy I rode up there and back like a big girl's blouse! :gay: |
Nice report, the O2 controller does give the motor more torque due to the corrected A/f ratio from 14.7:1 to 13.6:1, more torque does mean you will need to roll the throttle off to maintain the same MPH speed. At 14.7:1 the motor is not fuel efficient at all what it means you are getting a complete hydrocarbon burn off at 14.7:1 to please the Greene's.

Probably slightly more involved to install than I was expecting, nothing difficult mind you, but did require in my case, removing the fuel tank to get access the air box temperature sensor wiring.
I had really hoped to avoid this on my XT660Z, as I was already quite busy and "time poor" preparing the bike for a five day, 1750 Kilometer ride, through the New England Region of Northern NSW....mainly on dirt The O2 eliminator installation, was exactly as described.. "plug & play", only requiring a few cable ties to attach the black box to the rear of the fan. The fuel mod wires were scarfed into the temp sensor wiring, soft soldered and heat shrinked. I then tested the effect of the fuel mod with the Yamaha FI Diagnostic Tool and all appeared to be working OK. Set the dial to the 1700 position (5 O'Clock), and sat it just under the tank using velcro, where it would be easily accessible for adjustment if required. Was too busy to even take the bike for a test ride at this stage, as I was also fitting a DNA air box mod and pannier racks, brake pads etc etc. Headed off at 0600 on Fathers Day morning, and soon had to negotiate my first round-a-bout, which is less than 250 meters from my house. The bike managed it easily, with no need to slip the clutch etc, something I am usually quite prepared for at round-a-bouts!!!. Apart from that, I didn't notice a great deal of difference during the 1 hour transport to the meeting location, as it was mostly open roads with virtually no traffic, possibly due to the fact that it was a Sunday, and my mind was also busily preparing for the trek ahead. Met up with the rest of our group, and we were soon on dirt roads and into the more technical style of Adventure Riding. The first thing I did notice on dirt, was that the bike was now far more "tractable", I was no longer chasing gears, and by crikey, the bike was actually pulling from 2000RPM... even in third gear...!!!!! NICE......REALLY NICE...Any plans to play with the fuel mod were soon abandoned, as the bike was now a pleasure to ride, just as it was. I no longer had problems finding a gear and speed to handle any situation, not once did I have to go looking for gears or get caught in a gear that saw me riding too fast for the conditions and having to change down, only to have the engine revving its ring out. For the next five days we rode between 8 and 9 hours a day, on fast free flowing dirt roads in wide open country, to forest fire trails and singletrack through rain forests and slow, rock stewn mountain climbs, that literally shredded rear tyres.... and actually, I lost count of the number of deep stream crossings which the bike handled with aplomb. The Tenere conducted itself flawlessly throughout the trip, and I can say in all honesty, the bike now performs as I always hoped it would..... If you prefer off road riding...I can highly recommend Kev's O2 and fuel mod, along with Ohlins springs and T-Valves in the front end...SIMPLY BRILLIANT.!! BTW...I didn't bother with before and after fuel figures...I was enjoying the ride too much to care..!!! |
Importing into EU (Denmark)
The O2 controller seems to be in the need2have category :-)
If anyone within EU are buying in the near future I would like to tag along. The cost of handling imports directly to Denmark are close to robbery :-( The VAT and import custom are one thing but the fees are another story. So if someone within another EU country are willing to forward one to me i would appreciate it. I suggest paying Kev directly and then the kind soul for the import/forwarding cost. PM me if interested. |

And I need to document that the value is that low and if a gift that i have personal relations... The danish tax authorites now all the tricks and charges ~30USD in fee (on top of VAT etc) That is the reason to go trough another EU country that are not that strict (or keep the value down below ~15USD - but that won't work when they can see that just the postage cost is close to that) |
