Nice work mate.:3some:

Fitted Dna stage 2 filters and the Kev mod today. Nice easy job which has totally transformed the bike. Fitted some Leovince exhaust last weekend which definatley let the bike breath a little more but, as others have reported, with the filters fitted the bike now pulls from lower revs and is much quicker to hit the rev limiter. Happy days .:icon_bounce:

Got to thank Kev for a great mod and super fast delivery from Aus.

Thanks for the feed back Nick.

Hope the Sun comes out for you guys soon so you all can go for a ride.

Got my mod today.

had to remove the "bracket" on the fuel tank to get my hands down to the cable cause it was short.

everything went fine. Currently running only the DNA filter no DNA air box snorkel thing yet. Will use this when it arrives.

kev mod set to "3 o clock" feels like the engine works more "as it should do" Don't need to gear down as soon as the RPM get below 3k.

But I did'nt feel any "explosive" change over 3K RPM

So far so good ! thanks to Kev for all the help.

You need to fit the DNA snorkel mod to start to feel the HP gain, then crank the fuel mod to the 5 O-clock position.

kevmod

Did as you said Kev; cranked up to 5'o clock and inserted the DNA top.

After putting the kids to bed I took my favourit "close to home" trip. That trip includes a small "hill /top" (dont know the correct road word for that) I have always struggeled to find the perfect gear here. Up/down, up/down between 4 and 5.

With the filters and your mod it was only to keep the trottle in the same position. Without gearing down I could accelerate without any asmatic engine hestitation in 5. gear. Ofcause with the "thumper" feeling but that is now a romantic experience.

I love the "thumper" crusi'n in low RPM in turns and twist's. Feels as it should now.

All this has been written in the forum a lot of times but I just had to get it out :)

wonder why Yamaha did not get the fuel/air as this initially. Can't be the emission /pollution case, they make 1900 CCM beasts that are fully possible to buy and ride everywhere.

Is there a limit for different cubic range ? 50 gr co2 for up to 750ccm, 70 gr co2 for up to 1200 ccm etc..

Or is it simply that the engine is not build for the extra power and would last shorter with this kind of changes ?

There must be some reason, the competiton is hard and the producers sure want to make their bikes as good as possible compared to other..

99% of motor manufactures over build their motors with reduced HP & Torque for reliability. There again there are 1000's of modified XT660's with only a hand full that I know of that have let go.

I should think that driving on lower rews should be more healty for the motor then driving on high rews ? could they not make the fuel / air mapping so that the bike has the power and smoothnes at lower rews and the same as stock on the higer rews.

Or can it be that it is not healty for the motor to run on lower rews ?

Really want to do this mod,

just as an idea for cost ?

the mod 65 $aus then how much for the dna filter and air box cover ????

About �35 for the filter. Just cut your snorkel down if you don't want the DNA top. :tongue1:

I payed aprox 50 Euro for the DNA top. Just to make sure everything "is as it should" well worth it in my eyes.

same here. approx 50EUR for filter and about the same for stage 2 filter cover. Did have to wait a very long time for delivery but that was probably due to the lazy ass importer here in the kingdom with most non-functional governments in the world.

Thanks guys going to get selling to pay for mods :)

like the idea of a single can too

I saved some Euros ordering from Captmoto. He arranged everything with DNA and I got my filters pritty fast from Greece to Norway

one of the smallest countries in Europe, for some reason we need 6 (six) different governments, none of the actually get anything done and the federal one has just collapsed yet again. You Norwegians will need to try a little bit harder I'm afraid ;)

But back on topic: The DNA stuff and Kev mode are definitely worth it. The bike is transformed.

G'day Mr. Kev,

Quick question. I have an 2008 XTZ and the time has come to start tinkering it. Looking at going for the DNA filter, snorkel and air box cover and realize that I need your fuel mod.

My brother has a 2004 XTX and he has purchased the mod from yourself but has changed bike since so my question is will his unused mod work ok with my bike ?

Ta and keep up the good work.

Hi Kev,

He purchased the resistor from this site. I've opened it up and the number stamped on it is 701.

What colour is the resistor?

The resistor will have numbers stamped on the side of it what are the numbers, as there is 3 different versions of my fuel mod so I need to be sure you have the right one. Or use a multimeter & measure the resistance of the mod.

damomac

17-05-11 23:25

Hi Kev,

It's green and states B 1K. 701 is also stamped on the side opposite the knob !

It won't work on your Z.

18-05-11 11:57

Thanks for that Kev.

Ordering one now from this site.

Kev	18-05-11 12:18

All boxed up ready for posting in the morning, 820pm here in Oz.

Sweet Dreams then ! :)

Another testimonial here:

got the Kev-mod today and fitted it the same evening together with DNA filter and airboxcover... turned the knob at 6 o'clock.

... and PRESTO!! The engine is far more 'spicy', tacho sweeps through the rev-range to hit the rev limiter in 1st, 2nd and 3th gear with ease.

More grunt in lower rev range... more fun... and
the same behaviour as my MT-03 with K&N, Akrapovic & PowerCommander.

Still have the original silencer on, though it's cat is gone and there's a rather big hole in it.... it's going to be replaced soon by something else.

I also ordered one and sent you a separate mail since I forgot to mention it's a Z :):brain:

JMN	03-06-11 21:13

Same here.

Kev	03-06-11 21:48

Just to let everyone know my present 3rd generation fuel mod fits the XTZ, XTX & XTR, the only difference is the XTZ has different tunning settings to the XTX/R, otherwise the fuel mod is now exactly the same.

Unfortunately I am unable to update the main page on the forum at this stage do to technical problems & will do it as soon as possible.

I have also installed the Kev Mod, with a OTR foamfilter and stock exhaust. WOW! More power in the low revs, more agressive gasresponse!

I have installed the original intake without the rubber thing, fits perfect with the OTR foamfilter...its a bigger gap than the DNA! The bike roars like a lion!:041:

Pic: http://img600.imageshack.us/img600/9...0602095339.jpg

I have set the mod on 8:00 o'clock...seems the best setting.
I also have ordered a O2 Eliminator ( www.off-the-road.de).... i am curius what this Eliminator does!

Yep. 4 o'clock was too lean.

Gr. Johan.

04-06-11 20:04

Hi again,

I wonder if the OTR foam filter has a higher capacity than the DNA st 1&2 then, as Kev recommends 4-5 o'clock for for the DNA set up. 8 o'clock is at the top of the stage 3 recommended set up - interesting!
I need a bit of education when judging if the bike is running too lean or otherwise - how do you judge this? Is it purely the colour of the exhaust outlet or the 'feel' of the bike - or both - Would appreciate some pointers.

Cheers,

Ian.

Kev	05-06-11 00:06

Ride the bike at a constant throttle opening & adjust the fuel mod to find the smoothest ride & leave it set there.

The mod setting also depends on your ambient temp, the lower the outside air temperature is the more resistance you need to apply to the fuel mod to correct the A/F ratio. My mod settings are a guide line as tested with a data logger at 20 degrees C, it is best to play with the mod to find what your bike likes you can safely go too the max setting if needed if your bike likes the extra fuel. The mod is designed so you cannot over fuel the bike to cause any damage.

Thanks for all your fed back guys.:clap:
