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.

Yes.
