Hi Dino -

Out of interest, have you tried running the bike with just the stage 3 filter fitted, and blocking up the orignal top hole in the airbox completely and removing the original (stage 2) drum filter?

I'd be interested to see if the new stage 3 filter works better than the stage 2 set up...

Also, I've found that my Stage 2 filter and airbox lid don't seal particularly well - you can rotate the drum filter on it's seat even with the stage 2 lid screwed down tight... I've put a large rubber o-ring in the filter seat to keep everything nice and snug, but wonder if this is an issue you have come across with other customers?

Kind regards,

Jenny (currently unsponsored) Mo...

Something else I have noticed the XT660X as standard produces more HP & Torque then the XT660Z standard on the same dyno. This may be because the Z dyno run was with with knobbly tyres & the X had road tyres, what do you think Freez, would the total HP difference be that much with the different tyres?

Hi Kev,
The XT660Z that we worked on to develop the filter was offered to us by Yamaha Greece and it was equipped with a semi knobby tire; fortunately for us the tire was 70% worn away so we could work on the dyno with minimum loses.
With a completely street tire, hard compound, I would expect to see at least 1 hp more and better torque. But anyway this is not a problem for us, as we are on the safe side, we prefer not to be very optimistic and promise results that our customers would never achieve.

We will be sending Freez a XT660Z S2 filter for testing on his dyno, so we will see his results also.

Best regards,

Dino

Hi Jenny,
We didn�t try to run only the S2 filter for 2 reasons:
a) after completing our tests on the flow bench all the results with both filters where unbeatable, so using only the S2 on the dyno was pointless.
b) For off road use the more filtering surface you have the better it is; there is a factor that we call
� filter surface air speed� and the lower this speed is the higher the filtering efficiency.
Increasing the active filtering area and degreasing the speed of the air the moment it goes through the filter, allows more �time� for the filter to work and catch the dirt.
Now concerning the problem with the �filter moving around� unfortunately it is the results of inconsistence tolerance of the stock air box, which can vary from 1 to 3 mm.
Our filters have a tolerance of 1mm and if the stock air box is out of tolerance it could move.
If we would increase the height of our filters, very easy for us to do, the result is that the stock plastic cover breaks at the points where the bolts go through!
So you can realize that we have a very difficult case here.

Best regards

Dino

Ok so... people where are the first orders for these Stage 2 (3) DNA filter covers, I would hate that all the work done by Dino is done and people are still reluctanct to buy them, let see those PM to me with your orders...

After all, you guys asked enough times "when are the Tenere Stage 3 fliters gonna be ready?" Now they are so please make your orders.

Thanks!

If you want me to be honest then, at nearly 100 quid inc p+p I find a little steep for a air filter and I find it hard to justify that price (not saying it is not worth it). I think it would have to come down a lot in price before I would consider buying one.

That is the reason why I am not buying one. You did ask :bricks:

Im not convinced about the difference it will bring to a stock tenere.
I would rather wait until there are some reviews

True, but there won't be any reviews until someone buys one...!!!

I must say, I can see where Ricky is coming from - remember you also need to buy the Stage 2 drum filter and open airbox lid to make the most of it (hence why I wondered how much difference just using Stage 3 would make in my previous post), but I can see what Dino is saying regarding the stage 3 being supplementary to what he has already developed - for those who want the 'ultimate' perhaps?

i think the dna is the best bang for your buck, makes alot of difference, i fitted akros to mine and got around 1bhp with a stage 2 dna airbox mod and filter you would get close to 5bhp

maybe stage 3 isn't for you but a dna filter is a must, a friend of mine BIGB on here fitted a dna and stage 2 airbox mod and i had just pipes, we went out and he would leave me for dead, it would just pull away under throttle, thats why when i got home the first thing i did was was order a dna and stage 2 airbox.

i will be getting mine on the rolling road after crimbo

and that will be
dna filter
stage 2 airbox mod
Stage 3 airbox mod
akro's (De-catted)
and of course a power commander V
