I haven't gutted the airbox yet. I want to get my hands on an airbox to work on because i want to see if i can fit velocity stacks inside like some have done on Bonnevilles. So far I have installed a Breathe intake and an a/f gauge so I can monitor the various stages. Opening the base of the airbox will be done after the box has been gutted. My bike is an EFI so that's why I was thinking the billet intakes might not fit.
Stan, what is your torque in the 4-5000 rpm range? Never mind, I just re-read your post.
