Knock sensor mounting.
Top motor mount location.
a. Remove rear motor mount bolt from rear cylinder head.
b. Test fit Knock Sensor Mounting block to rear motor mount location using 3⁄8” x 2" coarse thread bolt (k) and 3⁄8" lockwasher (n). Test fit
Knock Sensor to mounting block (i) using bolt (j) and lockwasher (m). See Picture 6, below.
Carefully place fuel tank back into position to check Knock Sensor and mounting block clearance. Position the mounting block so that
the Knock Sensor or mounting block does not contact the fuel petcock or any other part of the motorcycle. If the wiring harness or outer
body of the Knock Sensor (black plastic portion) contacts the engine or any other part of the motorcycle, it could damage the Knock
Sensor, or interfere with its ability to detect knock. Special care for rubber mounted motors must be given. View Knock Sensor while
motor runs to make sure it has proper clearence.
c. After determining final position for Knock Sensor, remove mounting bolts and lockwashers, then re-install them on mounting block bolt
(k), torque to 33 ft. lbs., and Loctite® Red 262 on knock sensor bolt (j), torque to 11 ft lbs.
