+1 on the Rivco risers, they make a world of difference.
The new EFIs are a bit "snatchy" on the throttle, which when combined with the torque of the Speedmaster can make thongs a bit sporty if you're not used to it. I'm hoping that pulling the AI will take care of that.
Try one on, but careful, you may land up taking it home like I did.
