Measure the OD of the carb inlet. Ebay is full of after market filters. K&N is the best IMHO. You will pay for them too.

I am running a DNA filter #P-KY3SC11-01 for the 2011 DT300I. Same type thing as the K&N except K&N does not make one for the DT.

They are Almost lifetime. Wash, and oil. That is all there is to it. They will save lots of $'s over their life span.

any other , maybe a bit cheaper options ? just funny how much items i can compare to value of this filter . (sport windshield for an example )
there's must be someone on this forum using something better then stock . ( BTW im looking for online shopping so my only option is WORLD WIDE shipping. or middle east :D )(freakin' 3rd world )

Hey guy you can solve your problem by improving or change the air flow filter. The process of flow should be clear hence it would like to change. Other wise another option is that measure the OD of carb inlet.  Now Ebay is full of after market filters. And use it very softly.

can you please explain more about the OTHER option? ( more simple words will be great , im still kinda immigrate :D )

because right now , my DT is f*cking rocket ( tried kind of race , with "stock" DT , and surprizely ripped that bastard apart :))))
BUT , the only problem is that i cant hit full throttle at the start . i need to turn the trottle slowly , otherwise i feel rmp fails to stay stable and the bike "chokes" ( wounder how fast will it be after i'll fix this problem)

so that is the reason i would like to hear your options to fix the issue . my mechanic said that he can connect to the CPU and correct\change the air\fuel ratios , and thats what will fix this , but somehow i believe that more air will do the job (or most of it )

One fast wat to test the theory is do one run without any air filter at all. Don't continue to run this way but for one quick test it should be fine. Now it running restriction less doesn't cure your issue then a high flow filter will not either...........

yeah , i'll try that . anyway lots of people said im loosing air quality to air quantity . so i will try to find an optimized filter that will give more then the original , but not that Sparse for lethal damage .

I have not any good idea how to improve air flow filter buy i suggest you that you say this problem to the scooter specialist he solve your problem. If you find air filter in the market than i suggest you that purchase it on dealer shop its the best place for it.
