Doug Henry Airbox

Hey all, in particular Clarke.

I will be installing the Doug henry Airbox with Velocity Stack this weekend. I am currently running the DSP pipe which is aimed at mid to top improvements. The Airbox is designed to improves low to mid. Feedback from the Yamaha racing teams in Australia who run this combination are positive.

Vast improvements in mid to low and good improvement in the top end. But, I will need to verify this for myself. I need as much grunt and responsiveness as possible as I will be competing with Husaberg, Husky's and KTM big bores.

Expect some feedback Sunday morning US time.
