DNA stage 3 filter? Anyone?
My other exhaust thread got a littlel jumbled so i wanted to make this thread. Please dont fill this up with nonsence, id like to hear from people actually using it.
They claim 5-6hp with this filter. I dont believe it, unless they are claiming it with exhaust as well. Search doesnt come up with much. Has anyone used the DNA filter and the KN? Is there a noticable difference? Even if its 1 or 2 hp over a KN, thats worth it to me. I understand you need to re-jet or re-tune. Im talking the stage 3 filter kit, replaces the whole airbox and everything. Not OEM replacement. Anyone? |

http://www.dnafilters.com/en/news/pr...2008-2013.html It looks like a glorified K&N.

The DNA Filter kit looks comparable in construction to a K&N w/ the addition of a crankcase filter. The airbox design and HP claims need some proof, however they are possible depending on how the test bike was dynoed in the first place. Have you taken a look at the wiki? https://www.ninjette.org/wiki/Air_filters_for_newgens |

Not to derail much more but i have seen the wiki, it shows nothing of the DNA Stage 3 kit. And yes, it does look like a glorified KN, im not argueing that. If this thread doesnt generate results that are sufficient i will just email the company asking if they have any proof and what that 5-6 hp gain entailed.
I would appreciate only replies from people who have used the DNA Stage 3 kit and their results, or at the very least people who have seen it in use by someone else with what they thought about it. |

I live in Greece...Dinos Nikolaidis Airfilters is a very well-known company throughout Europe for its quality products and in Greece it is highly prefered over K&N even if more expensive some times....
That is a general rule applied here, like the preference you have for Area P's products (totally justifiable IMHO)... However there are a few things that must be said when it comes to dyno figures...just because there was a lot of discussion about these figures here when the claimed 5-6hp gain was announced and advertised.... so DNA after several greek forums demands gave the conditions under which those 5-6 hp were produced over a totaly stock FI bike 1) those figures are valid ONLY for the FI model 2) power gain of a max 5,9hp difference was the outcome of a fullLeo Vince racing exhaust system coupled with dynojet PC V and the stage 3 DNA product, which in turn was 1,2 hp (claimed) over the same upgrades but with competetive (K&N) airbox drop-in product 3) PC V programming was set for the DNA stage 3 product when dynoed the competitor... 4) no data on how many rolls on dyno for each scenario or humidity/temp conditions... So my guess is the product does have a gain over the competitor but somewhere in the 0,6-0,8hp of max power... so the gain is not pure horsepower from an airfilter...however there is a great gain that is not only there, but is felt too... for one even if the max hp is not so much improved, lower and middle rpm torque is greatly benefited because of the better/quicker engine breathing compared to the stock airbox drop-in products (that's why almost everyone over here withFI bikes have messed with doing stuff and driling holes to the airbox etc) the second thing is that the engine becomes far more quick revving throughout the rpm range, improving acceleration figures that give an "increased hp" feeling... So if you are talking about the US carburated version, results will definetely be different... that is all I know and can tell you for sure... whether the product is value for money or not is another thing just as others would point out that upgrading the 250 is also questionable as far as value for money is concerned... hope I have helped you more than I -perhaps- confused you..

Thanks Nick, i know its a popular upgrade overseas so i was hoping someone would chime in. Thats exactly what i was looking for, i was to eek every pony out of this little bike so i very well may go with the ecotron FI system and this DNA filter. Now just need to figure out the exhaust.

IMHO, once you see the gains from the 32mm TBs you will feel that spending that much on air pods was a waste of money when comparing gain/cost ratio... Shawn (garth285) can guide you through this setup since he already has experience with it on his turbo project...

I PMed Shawn but no responce yet, i checked out his site on it. The list of parts isnt long but i question whether or not i need the flywheel fromt he 300 for an FI swap? I dont see why i would, its mainly ECU, TB, misc sensors and fuel pump. Not a big deal, in this case though the DNA filter does not fit the 300 TB's, so i would have to do a KN filter. Trying to figure this out soonish so i can order everything and have time to dyno and install before June

ya ive read through both threads at time when i had no intentions of modding so i will re-check them out again. I dont know if i want to go through that much work to go FI, ecotrons may be easier. Or just re jetting....
Its a track bike that sees few road miles (maybe 1,000 miles a year), so im not sure. |

no one seemed to notice the big support bracket "dirt shield" which i believed was well thought out.
ebay: http://tinyurl.com/qgvv5l7 UK amazon: http://tinyurl.com/neeyc36 has anyone addressed support of the carb/ pod filter? rubber intake boots give me second thoughts. anyone have this installed? is it sold in the US? |

Well i did make this thread over 1.5 years ago, so at that time it may not have been listed to fit the 300....
I have since just done an area-p exhaust with the KN and did a re-jet. Made 30.5whp I then went and bought a bigger track bike...so the 250 doesnt get much attention these days.

update. tried installing this on the 300. shouldn't have made a difference since both 250 and 300 have a 50mm OD. but this filter's ID is 43mm!
awaiting word from greece. ordered r-0990. not happy. |

the latest reply i've gotten from the seller in greece is that DNA "built only for previous TB."
i know my carburetor is a keihin cvk30. i'm not aware of prior 250 versions... is there one where the air intake is ~44mm? |

The filter is designed for the FI version of the 250, which has a throttle body with a 28mm inner diameter and likely a 44mm outer diameter.

Are you measuring the part that slips over the carb or the opening designed to align with the venturi (i.e. the smaller opening)?

seller won't stand behind their mistake. they've updated their page to now reflect EFI fitment. horrible company. buyer beware.

well i bought one. took about 10 days from greece. off ebay. i was wrong, this is simply a mat, no rigidity at all. now just more weight hanging off the boots. i will investigate using something perhaps with the oem airbox frame mounting points.
