Hi all.

I got my Kev O2 controller in the mail the other day.
My 2008 XTR surged/ jerked/ bucked in an annoying way in low and medium revs.
This was so irritating that I reved it a lot and drove it was too fast not to feel the surge.
Mounted the Kev O2 controller and took a 550 km long trip to northern Sweden ( from The capitol Stockholm)
This mod has transformed the bike, almost no surge, the driveability so much better now.
It now drives like a one cylinder bike should, I compare to my previous Yamaha SRX-6, Yamaha XT 600 and Honda XR 600.
I can gear up much sooner with no discomforting jerking motion and my smile when riding is so much greater.
The mod arrived quickly in the mail and was easy to install, (Im no mechanic)
Overall Im very happy with this mod, money well spent.
I highly recommend this mod.

Apart from this mod I use the DNA stage 1 air filter, snorkel in place, everything else is standard.

Big thanks to Kev for making this mod!

Anders

Thanks for your feedback glad you are happy with your results, nice to hear the little black box has made your ride smoother.

Got my O2 Controller in the mail today. 10-days from Australia to the most northern parts of Sweden on the other side of the globe.
Will install it tomorrow, excited!

My O2 controller will hopefully arrive in a couple of days. Shipping from Australia to the middle part of Sweden

I have now used the bike with this mod for more than 1200 km.
Still very pleased.
Before the mod was mounted the fuel light came on at around 180 km of riding.
Now with the mod fuel light turns on after 200km of riding.
Same conditions, same highway, same speedregulations, same weather, same single rider with cargo.
To me it seems like I save fuel with this mod.

Im happy

Anders

I'v tried out my controller this weekend aswell.
The bike is a bit stronger on low revs and the surging has been less. Its definitly not completly gone but much better then before.
So Im satisfied with the product.

Thanks for the feedback guys.

Got my O2 controller today.. Can't wait to install it this weekend

Hello!

I installed the O2 controller yesterday and took quite a long ride today with a mate. I have shared feelings about My experience with the O2-controller.

The bike got another motor sound with the O2-controller installed, I can kinda hear that it gets more fuel or something. The sound is sort of more deeper and more rumble. It feels like I can use a higher gear on lower speeds now.. But I have still problem in the 30-50 km/h area (approx. 18-31 mph). It is still quite jerky in those speeds.. 30-40 km/h (18-25 mph) I use the second gear and 40-50 km/h (25-31 mph) I use the Third gear. Sometimes it is good (and it was quite good from time to time before the o2-controller installation) but sometimes it is quite jerky any way.. As Said I can hear that the motor sound is quite different, but it stills surge/jerks a bit in very low speeds..

Anybody that recognize this behavior or is your bike good in the low speed area with the O2-controller installed?

Did you just by the 02 controller and not the Kev fuel mod? If that is the case then I suggest you get that too because that in conjunction with your 02 controller will solve the jerking issues once and for all. Talk to Kev.
