Anyone out there running the Hotcams Stage 2 cam in the 650R? I ride everything from tight technical mountain trails and moab slickrock to wide open desert racing and sand dunes. Trying to decide between the stage 1 or stage 2 cam. There seems to be a LOT of guys running the stage 1 but hardly anyone with the 2. How did the stage 2 effect bottom end power, is it still a torque monster or did it shift the power range up to mid-top end more. Basically I wanna know if it will still be OK in the technical mountain trails and slickrock still with the stage 2...I KNOW it will be good for the desert but don't know how bad it will affect low end. Does the stage 1 make much of a difference...is it even worth it? I have full exaust, edelbrock, hop up kit, everything else stock. thanks.
