What size main jet for a gilera dna 50 once tuned?

I have installed a malossi airfilter. Now when i give the bike full throttle the wheel does not more as if there is to much air getting in. I have tried a 60 main jet then a 70 does anyone know the exact jet size or anything that could be wrong?

I have tried the orignal filter the power is still there. should i try an 80 jet or is that to high?

use the main jet you had in to start with. you will see 3 cutouts in the fet at the top with a sir clip just move the clip from the middle cutouts down one

Try the original filter on again to see if the power comes back....normally for a free flow air filter the main jet size goes up 10% but it is a gamble. Be warned - if your bike is running too lean it will overheat and you could burn a hole in the piston.
