Clutch Adjustment - Bob Gorman
A just released service bulletin revises the clutch freeplay specification to 12mm
between the knurled nuts and 7mm at the lever. This is revised from 10mm and
5mm respectively.
It appears that improper clutch adjustment has been the cause of many shifting
problems. In order to obtain the new clearances you'll need to adjust the clutch at
the motor. You can have your dealer do it next time you have service or you can
easily do it yourself.
Equipment:
13mm deep well socket
10mm socket
socket swivel attachment
socket wrench
6" socket extension
13mm box end wrench cutoff to 2"
Procedure:
Place the extension on the wrench
place the swivel on the end of the extension
place the 13mm socket on the swivel
approach from the left side of the bike
reach in and just crack loose the 13mm locking nut at the rear of the tranny
place the 2" 13mm box end over the locknut. This will keep it from turning
remove the 13mm socket and replace it with the 10mm socket
reach in and back out the 10mm adjusting nut until you achieve spec.
give the 10mm nut another 1/2 turn
remove the 2" 13mm wrench from the locking nut
replace the 10mm socket with the 13mm socket
reach in and tighten the lock nut.
In the process the 10mm will regain that 1/2 turn you put in.
The entire adjustment takes, maybe, 2 minutes.
