DNA Filters

Postby Finnster » Tue Jul 04, 2006 5:01 pm

Does anyone have a source to buy DNA filters? They dont have any distributors over here in the U.S.

The SD part number is:

P-KT9S06-01 for the KTM LC8 990 SUPER DUKE 06'

Im sure its the same for the 05' SD's as well.

Thanks!

Angelo,

That would be awesome! I will take you up on that offer. Do you have a paypal account? Hit me up on my email...I think you have it.

Installed my DNA filter that I bought on ebay yesterday. Quality piece..fit perfectly. I let the bike idle for 20 minutes and then took it for a spin. Bike runs great...I cant really tell if its running better or not....sorry, no before and after dyno runs. I suspect the best reason for this is the fact that I can clean and reuse the filter.

I really love this bike!

ditto

had it fitted last tuesday, seat of the pants dyno feels about the same. certainly not worse than before...

one funny thing is that the bike used to cut out at traffic lights, doesn't anymore... not sure if it's the DNA filter though ... I also get less backfiring when decelerating (which can be good or bad depending on how you judge it)

Rode again today...I think it runs better....it might be my mind justifying the purchase but it was ripping up wheelies today!

Had a DNA filter installed today. Bike runs better. It breathes easyer. A must do IMO.

Well, DNA air filters for ride_ktm and myself arrived in the post today... Impressions coming soon...

I'll have a before and after Dyno done too that I'll post up in here as soon as it's done (this weekend no doubt)... For those that are interested to have a look.

Dynographs coming soon, but I can confirm for a SD with pipes and akro mapping, a DNA filter is good for about 2.5 Hp. Fitted the air filter while the bike was still on the dyno. ;-)

Thanks Lockers, this is useful info! Do you have Akra slipons or a full system?

I would have prefered the power gain in the low end and midrange but still a good improvement for just swapping an air-filter.

The shape of your graphs look identical to mine. You can see the sub-optimal fuelling up to 7K just by the shape of the graphs. We really need the possiblity to modify the fuel maps on our SDs to get the best from them.

I am in contact with Tuneboy (Wayne McDonald) from Australia. These guys are the experts on Keihin EFI systems as used on Triumphs. They are more than willing to make their TuneEdit software available for the EFI KTMs too but they need a cooperative dealer and/or owner of an SD to test and set things up. This would be 'tuning-heaven'. Much better and more sophisticated than a Powercommander or Rapid Bike Module. Have a look:

http://www.tuneboy.com.au/

BTW, I would help to speed things up if they received more inquiries from us SD owners. HINT!... :)

Yes, I would be up for a Tuneboy also. I will send them an E-mail to show my interest. This would be the ideal solution to set up the fueling, disable the SAS?, etc. Also its looks like the Rapid guys have gone quite, maybe their installation didn't go well?.

Have emailed wayne also........ when i had a speedtriple the tuneboy was just taking off and i watched with interest its reception.... pretty soon there was lots of posative comments in the triumph fraternaty..... and lots of choice regarding different tunes for varying applications,was interested in purchasing one then but sold the trumpet..... would seem ideal for the sd now though as i dont have the Akro's fitted for the Akro map to be perfect for my bike....... i did download a preview of the tuneboy software at the time to get a feel of its functions,looked good and so easy to operate with a lead and laptop..... will have a search to see if i still have it

JUst to add my positive experience and 'backside dyno' assessment - the DNA filter is the best £58 I've spent on tuning. Throttle response is crisper and the engine more responsive, the bike revs faster & pulls harder - wheelies are even more frequent. I thought I was imagining it at first, as immediately before riding my SD for the first time with the DNA fitted, I'd done a trackday on a CBR600RR, but no, I'm not mistaken - the dynograph confirms it. I'd recommend anyone doing this mod. I was going to lower the gearing, but now I'm not going to bother, such is the improvement of the bike.

Where did you source your DNA filter from for £58 ?...........

Ebay. Edrivestore is the seller. Including v.quick postage from Athens, total was £63. Bargain.

The DNA filter has a slight lower delta P, you might need to remap the engine.

OK the weather finally allowed a test ride.

Wow... this filter really works! :shock: A clear improvement in throttle response and smoothness. The sometimes snatchy and jerky FI response is virtually gone just as the occasional surging on small throttle openings (crawling through traffic). Amazing! Midrange power & torque feels fatter and smoother too with a slightly darker sound from the engine. Nice... I couldn't really test top-end power but I'm pretty sure that improved as well although not very important for me. It isn't exactly 'lacking' in this area... :wink:

I'm not yet sure how only an air filter can make such an improvement in throttle response, smoothness and rideability but it does. GREAT!

Have you all got aftermarket exhausts or are some running the DNA filter with stanard exhauts?

Madmaxmasalla,

lower delta P means that the air runs easier through the airfilter. Delta is difference, P is pressure.

Sorry for my late response.
