I just ordered the Stage 2 DNA filter from af1. How hard is it to remove the gas tank for the install?

not hard at all if its the same as the 750,
remove the seat,
2 bolts behind where you push the key into,
be careful not to snag or break the radio wire around the barrel,
lift the tank,
youll see the air box,
remove screws around the airbox, these are the top screws,
the tb velocity stack screw off, remove old filter, replace with dna,
and enjoy the roar!!!!!

Been waiting for a while to hear if anyone likes the DNA filter or any reviews once fitted. I know the DNA air filter made a big difference on my 990 SMR.

I have it and have driven ~150km with it this season. My dealer said he likes the sound, but unfortunately he had just sold his demo Dorsoduro 1200 before I picked up my bike from him again, so I wasn't able to make a comparison video :( It seems to make the bike a bit louder, but without a direct comparison I'm not sure if that's only in my head.
Haven't tested the power gain yet, the shaking handlebar* at speeds above 240km/h (150mph) scares the crap out of me and I let go of the throttle. The fastest I drove was 248km/h (155mph) with the original filter and I didn't dare to go any faster with the DNA S2 Filter :crybaby:


*(whats the correct word for that phenomenon, can't find one in any dictionary "lenkerschlagen")

"lenkerschlage" in inglisch is a "tank slapper" ;)

i will try to install the air filter this weekend ... hopefully i can archive this ... maybe somebody could make a little "pic tutorial" how to get to the filter ? *pretty please* :crybaby::D

I put the stage 2 on my 1200 last week. I didn't take any pics but it was very easy. Maybe took 20 minutes. There is enough slack in the fuel pump lines to just move aside so you dont have to disconnect that. And if you decide to run power for gps or anything its a good time to do it while the tank is out.

ok ... then i must be stupid ... had a look at it and was confused, tried it with the tips of "shootmyscoot" but that didn't help me much either :bangwall:

What I did was first removed all the plastic fearings from tank then removed the bolt that covers the ignition switch. There are two bolts underneith that that bolt the front of the tank down. Then I removed the seat, battery cover, the battery hold down bolt and the bracket right at the rear of the tank. Then you should be able to lift the tank up a little bit to remove the vent lines on the right front side of the tank. Then set tank aside without removing the fuel line make sure you dont have to much fuel in the tank though. You will then be able to take off the air box and remove the stock snorkle setup and replace with the stage 2.

It's dead easy to install the DNA stage 2 filter. the snout that retains the standard filter is then no longer required or fits as the dna 2 comes with a metal surround that makes the snout un-usable. I am fabricating a extruded ally mesh to replace the plastic panels that fit inside the frame behind the headstock to allow fresh cold air strait to the cleaner. With those panels out and the dna filter fitted it sounds like she's trying to suck your nads off. Took me 15 to 20 miutes to fit the filter. the hardest part was to get my big mitt in to release the fuel line and wire loom. Sorry i can't post any pics,some mongrel nicked my camera.

I was going to also remove the front plastic piece but I decided it might be better to wait until someone has a good way to tune these bikes I don't want to lean it out to much.

Thanks guys! The filter is gonna be here friday, so this weekend I'll install it. :banana:

I posted a few pictures on the German apriliaforum, don't know if I've already posted them here but it won't hurt if I post them twice.

No chance of that, these run so rich its ridiculous once you de-cat them. Has anyone noticed the DNA filter making the bike run leaner....I'm interested as without a proper tuning method I'm running out of ways to lean the tune out short of a super expensive ECU replacement.

If you have pipes running the DD1200 with the DB killers in place works better for closed loop running. Closed loop
control on Motorcycles with their short exhaust pipes combined with a free flowing set of slip ons and running at lower rpms is usually way too rich. This has everything to do with atmospheric air reversion into the exhaust pipes at lower rpms. Basically reversion allows the o2 sensor to be exposed to too much air, it senses lean because the lambda probe cannot tell the difference between reversion air and oxygen left over during the combustion process. DB killers reduce reversion air more than anything else beneficial they do.

If you still have stock pipes and catalyzer...well that just may be too rich in terms of mapping or Ag/r target values.

That's wise words Micah, makes perfect sense, I'd never thought of it that way.....now I wish I'd bought the arrows instead of the Leo's even though I love the full carbon. I wonder if the Arrows Y pipe with the cats would fit with the Leo's and if they sell it separately?

Got the 10,000 klm service done today and stg 2 dna put in same time by sean at Brisbane aprilia (Springwood)
Man, night & day difference! Breathes heaps better!

Some more pics for the install procedure, hope they are helpful. Don't know how you guys did it without removing the tank!?! :eek:

150km to try out the new filter. At 2 sets of light when I was stopped the revs slowly went down and eventually it stalls... this was happening a while ago when the demand sensor / fly-by-wire and o2 sensor went faulty and it fouled all plugs and had no power above 4000rpm.... however it's running fine with heaps of up and go, but the stalling issue happens when i stationary.... Can anyone suggest what the problem might be??????

Hi
Do u guys use airfilter oil for the dna filter.

Mr.Dorso
09-27-2013, 01:15 AM
I did.. K&N Filter oil, spray on

I have a pair of GPR slipons without catalyzers, so if i install a stage 2 DNA filter, will the bike run to lean, and do i have to do anything with the fuel or am i good to go.
Best regards Micke

Who is running just the DNA filter? No fatduc..

Is it running fine? Cheers.

I've installed the DNA Stage 2 last week and I've also a Leo Vince without DB Killer. So far I'm not positive impressed about the change and I'm thinking going back to original.
I owe a 2011 model without any update on the software and the bike was always running smooth despite the smelly clothes or backpack.
Since I changed to DNA the bike feels not smooth anymore and the engine has some misfire and sometimes the engine just go off on a traffic light which I never had before.
My local Aprilia Dealer wants to install the new mapping but I’m not sure if this would help.

I have no Problems that the engine is running hot with the dna except in stop and go in Kuala Lumpur traffic jams. The bike still runs quite rich because the smell in clothes are still there..

Greetings Bernd

The new software should make a positive difference for sure.

Gabro told me he is close with the chip for the DD1200. Fingers crossed it wont be far.

Mr.Dorso
12-22-2013, 04:10 PM
Gabro.. Chip..? Whats this..??

Brinks are you running the DNA stage 2 without fatduc?

Brinks_2
12-23-2013, 08:46 AM
Yes mate, a bit rich tho. Looked into a fatduc for the DD and decided it was already running rich enough. Had heard Gabro was looking at a custom chip, so decided to wait. Gabro does chips for Aprilia's, has been doing them for years on the rotax's. I have one in my Falco, which has helped cornering dramatically due to improved throttle response. If he can get one done and says it's improved, I will be all over him to purchase one and install it. Do a search on what others say after they have installed a Rotax chip from Gabro. :)

Mr.Dorso
12-24-2013, 01:16 AM
Cheers Brinks will look it up. Still running rich without a fatduc and stage 2.. Wow! Might uninstall fatduc and see how it runs.. Do you run sport mode or touring mode? No stalling or drop of revs at lights?

almost feels like some sensors may be faulty again...

Brinks_2
12-25-2013, 05:20 AM
Run sport all the time unless in heavy rain. Revs drop a little at the lights, but when they are going to green I blip the throttle to pick them up again. Sell the fatduc and wait for Gabro would probably be best as they seem to run quite rich, or as Micah says put the baffles in around town and remove them when a sprited ride is immanent. :)
