I CAN'T THANK YOU ENOUGH FOR THIS.

I messed up the original thread so I had to do this, sorry:

Ok I'll go first. I've only got the stage 2 ( more than likely get a stage 1 at some point ). Its made the biggest difference to my bike, performance wise.:icon_mrgreen: It smoothed it out a bit and made it have more go everywhere. I found I can even go that bit slower in each gear too which makes town riding much better. At the time of fitting I still had the original exhaust and the intake noise was then louder than the exhaust. :icon_burnout[1]::icon_thumright: GET ONE IF YOU HAVEN@T ALREADY, you wont be dissapointed.

I have a 2007 XTX with a DNA stage 3 air box. What can I say, this is the best air filter mod I have tested on the XT660, it produces the most HP & Torque than any other filter set up fitted to an XT660X/R.

Shows a 7.2HP, 6.13 FT/LBS gain over a standard XT660 on my bike, thats a 18% increace in HP & 16% increase in torque.

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.

I have got a stage 2 DNA filter and top, bought it from Big Den when he sold his bike after 3 months (long time for him)

XT660Z Tenere - DNA Stage 2 Filter & Cover
 

I have the DNA S2 setup, along with a PC-V (supplied by Simon with a pre-installed map for this setup). Standard cans.

I've not done anything with the 02 sensor yet or the AIS.

The bike feels no different from stock up to around 4000rmp, it then pulls with much more purpose and focus pretty much constant all the way to the red line.

Riding the bike, the main difference I find is during overtakes. The Tenere always felt a little lethargic and requiring overtakes to be planned in advance (to get the gear/rev combination right for a swift manouvre). With the DNS/PC-V combination overtakes can be taken at shorter notice.

When the bl00dy ice melts on our lanes up here I'll give her a try to see the difference. I've not yet tried with the bike loaded up either.

It might just be me, but I'm sure the bike is a little louder than before - no idea why or how - maye I've just cleaned my ears out!

Air intake induction noise ?

I have the stage 3 filter on my X it is very well made, makes a nice induction roar, also makes the bike perform better than the stage1+2 filters ,they are a bit on the pricey side but i am glad i got one as the bike rides a lot better with it

Stage 3
 

Capt Moto,

I ordered and have recieved (via you) the air filter and the open top cover for the XTZ. I already had the air box side cover. So I am ready for stage 3. I have ordered the PC V from Simon and he is going to sort me out with a map allowing for Stage 3 + Apropovik pipes. Once I get it all together I will let you know the results.

Thanks

Colin

Ive got k+n stage 1 (fleabay), stage 2 dna (off fran) and home made kev mod and drilled air box and snorkel removed.
Did stage 1, air box mod, snorkel removel and kev fuel mod in one go and it made a big difference to low down pull meaning less down changes and also much smoother power delivery through the entire revs.
Installed stage 2 and had to raise tickover as it kept cutting out, (idleing too low). Also turned kev mod up to full now as plug was a bit dry after fitting stage 2. Further improvement to smoothness of power delivery and seemingly more power throughout the entire rev range.
When I removed the snorkel, drilled the airbox and fitted stage 1 there was a very big difference in air induction noise.
When stage 2 was fitted there was extra air induction noise again, (now pretty loud!), but not an issue to me.
In my opinion well worth the money spent.
Next move, MTC cans and power commander.
Thanks to Fran + Kev.:SpinHappy_15XK8L:

Fitted DNA stage 2 recently. brspecial had an offer on.
I removed the snorkel and fitted home made fuel mod+02 sensor bypass thing within the first week of having the bike.
On both occasions I had to raise the idle to prevent stalling, and noticed a nice change in sound from the intake, and noticed abit more go. (maybe the sound was abit odd to me at first, probably because the air intake isn't usually louder than the exhaust lol.)
I've got the fuel mod adjusted down by 4deg now. as the recommended 5 I think is for both DNAs and holes drilled. I forgot you can get a rough idea from the sparkplug colour/condition. will have a look soon.
I still can't bring myself to drill the airbox, being a newish bike, maybe I can be convinced.
I dropped a tooth on the rear sprocket a month or so ago, this does make the gears slightly longer. but I definately noticed it was slower to pull. Now with the stage2 I got the zing back. I'm gonna have to check Kev's 'how much power from each mod' section again, see if it's worth getting the drill out. ;)
Maybe I should get DNA stage1 first.
and then likewise Stumpydave, cans and a nice PC.
slowly but surely the mods fall in place.....

Mines a 59 plate bought october last year with 000000 on clock.
Ive actually gone slightly further than drilling my airbox, I've cut the sides out of it behind the stage 1 filter. It started out as drilling but then I joined the holes up!!!! My line of thinking is you can pick another up of fleabay for about �40 so what the heck, its only money!!!!
If you look at what kev says though he says to drill 28mm holes then if you want to reverse it after you can put bungs in the holes.
Be a devil, go for it.

Capn got the XTZ Stage 3 from you. Bike getting it's winter spring clean etc at the mo' so no results for now.
