after talking to yoshi over and over, the engineer confirmed they do not make a dual high mount because it would take away from the bike.

so hmf makes one....does it take away from the bike?

HMF gets pretty high rating for performance and quality. The reason most manufacturer's say they don't make it because of power loss are full of shit, they don't make it because the don't have the tooling set up for it and or R&D. If you don't sell enough of them you won't make your money back that was spent on R&D.
