Which airbox?

i did not get the tnt box in the end because i found out its way too small. 18cm x 11cm.
I will get a kart box in the future and not have a irritating open filter ever again

 

yeahh thats what i was saying earlier in this thread, you want to be looking at 125cc + kart airboxes really...and then the problem will be finding somewhere to put it...not everyone is prepared to hack out their under seat storage area like me for an air box hock:

The std 125/180 air box looks huge, and im sure with a bit of detail work and streamlining inside would be good enough on a 172

 

Can someone help me out? I am putting this TNT airbox on my moped. Currently running a malossi filter, and will need to downjet and tune the carb again... Question is how far down do you think I'll need to go with the jetting to run this airbox?

This is what I have with the malossi filter...
21mm Dellorto carb
96 main
40 idle
50 slide
W9 needle

 

Didn't mean to post the pic 4 times. Haha.
