i might rarest you guys later when i receive and fit them about fine tuning :)

Hi, iShoe.

I think that with DNA filters (1 and 2), in order to optimize fuel mix, you have to enrich the moisture. So, the consumption, depend of how much you enrich it. By.:thumbsup[1]::thumbsup[1]::thumbsup[1]::thumbsup[1]:

To get the most out of these filters a fuel mod is recommended, by adding more fuel & air we get more HP & Torque.

With the extra HP & Torque you need less throttle to maintain the same speed, then if you did not have the filters & fuel mod, so infact there will be very little change in fuel consumption.

One thing will change your bike will go like hell with those filters.

thanks Kev, I'm been flowing your work and posts on forum ;)
correct me if I'm wrong, fuel mod can be done with your mod kit or power commander? i think i read somewhere that 2009 XT has something changed so its really good in auto balancing fuel - again maybe I'm wrong.
Or all i need to do is to flow this tutorrial ? http://www.xt660.com/showthread.php?t=55

There is quite a few fuel controller these days.

Fitting a fuelling device almost fixes the surging, there are a few options.

Hi,
this is my way in order to enrich the moisture.

In the first position (MEMJET), we apply a fixed resistance of 6 Kohm.

In the second position (MEMJET + NTC), we apply to normal NTC air temperature sensor, a fixed resistance of 1.5 Kohm.

Of course the value of resistance is settable. I call it "fixed" because, after many test, are the best values. By.
