The CSS unit has been successfully installed on a few
R3's already. I downloaded the complete instruction sheet from another website about a year ago. The big problem is that the
R3 engine can't maintain enough vacuum to properly modulate the servo unit under all conditions, thus the auxilliary vacuum pump is needed.
The CSS unit is completely hidden from view. The servo unit fits handily behind the left tin with the actuator cable routed along the frame tube and exiting right in front of the Bear Claw. The CSS unit picks up it's speed signal from the coil trigger and interprets it as ground speed. The problem arises with the vacuum pump. It has to be compact as there is precious little room under the tank or seat to mount a pump. The Ford SuperDuty pump is compact and self regulating, that is, internally switching.
I may just install the unit this winter and take off my Flipmeisters 50 cent throttle lock.
