CAUTION
Knock sensor must be mounted to the rear cylinder or rear top motor mount. Mounting the knock sensor on the front cylinder will
provide an incorrect signal.
1- Knock sensor mounting at Location 1:
Rear cylinder head
A. Remove the plug from the knock sensor mounting location in the rear head (if present).
B. Insert the 5/16” x 1 ½” coarse thread bolt through the 5/16” lock washer, knock sensor, and ¼” thick spacer.
C. Apply blue thread locker to the end of the bolt and attach the assembly to the rear cylinder head. (See picture 2)
D. Torque the bolt to 11 ft-lbs.
2- Knock sensor mounting at Location 2:
Top motor mount location
A. Remove the rear motor mount bolt from the rear cylinder head.
B. Test fit the knock sensor mounting block to the rear motor mount location using the 3/8” x 2” coarse thread bolt and 3/8” lock washer which
are provided in the kit.
C. Test fit the knock sensor to the mounting block.
Position the mounting block so that the knock sensor or mounting block do not interfere with the gas tank or any other part of the
motorcycle. If the knock sensor wiring or the outer body of the knock sensor contacts the engine or any other part of the motorcycle, it
could damage the knock sensor, or interfere with its ability to detect knock.
CAUTION
CAUTION
D. After determining the final position for the knock sensor, remove the mounting bolts and lock washers, and apply blue thread locker to
the bolts.
E. Re-install the assembly and torque the 3/8” x 2” mounting block bolt to 33 ft-lbs and the knock sensor bolt to 11 ft-lbs.
Hold the knock sensor in position by hand while torquing. Do NOT use pliers or damage to the knock sensor will occur.
3- Once the knock sensor has been installed on the engine, plug the sensor lead into the connector for the Knock sensor on the S&S EFI wire
harness.
