Full system - disconnect exup motor?

Hi. Have bougt A full system for my R1, and i've disconnected the exup servo motor, but now the tacho ****s up :-D so how do I make the tacho work normal again without reinstalling the exup servo motor?

Relacing the servo motor is the easiest fix, otherwise you need a little box of electronic trickery called "Sams Servo Sub" which plugs into the loom in place of the servo mtor which fools the ECU. I think they are about $100 but where you buy them from I do not know. EDIT: Here ya go: The stock servomotor and associated cabling weigh 19 ounces. Sam's Servo Sub weighs less than 1 ounce, is solid state (all electronic) and thus has no moving parts to eventually wear out. http://samannasystems.com

thats damn expensive.

the cheap way is to remove only the cables to the exup
