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
