 On the other hand, for 1991-1993 models, which also have five-speed transmissions, while the clutch operation is the same, the Ball & Ramp Assembly is mounted to the inside of the Primary Cover (as illustrated for 1984L-1990 four-speed models). This necessitates the removal of the Primary Cover in order to replace either the B&R unit or the Adjuster Bearing unit on those models.
-Also note that the clutch pressure plate for 883 models changed. From 2004-later, the 883 models used a lighter clutch pressure plate, while previously, both the 883 & 1200 models were the same.((http://hammerperf.com/883conversions.shtml))

 Remove the Clutch Inspection Cover (off the Primary Housing - Small Cover on '86-'93 - Large 'Derby Cover' on '94-up) (You may have to loosen or remove the left mid-mount foot peg) - be careful as you remove the cover because there is an internal spring & Release Adjuster Position Lock Nut - Remove the internal spring & Release Adjuster Position Lock Nut…
 Turn the center screw of the Release Adjuster clockwise one turn away from the original position to be sure you are fully unloading any pressure - then **slowly turn the Release Adjuster screw COUNTERCLOCKWISE until you feel ANY CHANGE IN TENSION**  - Do this a few times to be sure you feel the right spot where tension begins – When you're satisfied you have the right spot, turn the adjuster screw back __clockwise 1/4 to 3/8 of a turn__  to be sure no preload tension is on the Diaphragm Spring.

 ===== Upgrade Clutch Diaphragm Springs - Pressure =====
+Below are a list of upgrade versions. The 'xx% stronger' are claimed values by the respective vendors.
+Energy One suggests that if you are using a diaphragm spring of +25% that you should also upgrade your pressure plate to a billet version because they have had issues with the stock cast pressure plate cracking. ((cjburr at http://xlforum.net/forums/showpost.php?p=666722))
