Kev was kind enough to let me help him test this mod and i can say it works
it only took about 10 mins to fit loaded one of Kevs maps and went for a 50ish mile run town and country ran well at higher speed and it happily ran at 30 mph in 4th gear and 40mph in 5th , there is hardly any surging on the bike now i would say at least 90% better

This is very true Paul. I can run mine at 40mph in 5th, but thats not to say you should do it very often though as it can stress the engine a little when you open the throttle.

It is however a good sign because it means you are able to map that fueling area on the bike to the point where you can do it.

Before hand, I had to be doing a minimum of 50mph before attempting to put the bike into 5th because it buck like a broncho ;)

Sounds good to me....:bcake:
and is your bike custom dyno'd yet Paul?

From the sound of it...my bike already runs better than yours, Paul, as I had a custom dyno (Iknow figures were a bit wonky) but my bike has not been a bucking bronco...don't forget Paul, they have different fuel in Aus.

I think with the guys who ARE NOT into modding like us, the "main stream" of XT riders, if you get Kev's fuel mod, and the O2 Mod, you can "ride and adjust". And it should be 100% better!

No i have not had it on a dyno i am running a map Kev sent and it seems to work so don't think i will bother

personally speaking, with what I have fitted with my autotune and my own fuel map because of it, my bike is 100% fixed without a doubt.

It rides so incredibly smooth now, the difference is incredible.

I agree a custom map may be required to make the bike run 100% better.
But i am happy with the map i got of Kev and will give it another longer run when the weather is a bit warmer to see if makes any difference

OK guys, my current O2 mod with my Kev fuel mod is now up & running.

Ok, but thanks anyway for trying it out anyway. However, I will for sure get myself a PCIII and your new O2 mod in spring of next year, I'm not gonna miss out on this one!

How the O2 mod progressed there were other versions, here is the last 3.
