No airbox will always make more peak HP than a stock airbox, there is no denying that fact. Of course, none of us here need peak HP, we need ridability. But we dont seem to let that stop us from trying to attain a few more precious ponies.



Just everyone has the rights to do what he prefer with it's own bike.
But many suggest airbox removal like the only right/best way to obtain a good performer's bike.

Finally I came to visit a guy who has a Speedmaster, he showed me an air filter and his airbox dimension and internals.

I see that the air filter is big near 2 pods, with a diameter of the oval mouth of the filter bigger than the carburetor's venturi.

Opening the airbox both from the snorkel and from the opposite side there's enough air delivery for a good air/fuel tuning.

I told to that guy about the snorkel and airbox mod, and he is interested in doing it.

Keep in touch, I'll write every experience with it.
