 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 in 2004. 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))

 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.

-You might consider replacing the stock bearing, P/N 8885, which is a standard ball type bearing (equiv. to 6200). Using an angular contact bearing, which provides additional support in the axial direction, is a better alternative for this application. The upgraded replacement would be 7200B (not supplied by HD) and is an angular contact bearing. Thus, it is important to orient the bearing in the right direction when pressing the bearing into the Release Plate.

-The wide side of the 7200B outer bearing race should be placed into the release plate first. This also means that the narrow part of the inner bearing race is first into the plate.

-When correctly assembled, the narrow part of the outer race and the wide part of the inner race will each be exposed on the insertion side of the release plate. The Adjustment Screw is inserted into that wide side of the inner race, as shown below.

+This was to reduce the effort required to pull the clutch lever. There was also a change in the\\ clutch cable in 2007 to help reduce the clutch lever effort.
-HD has a Performance Clutch Kit (Number 38002-04) designed to fit 1991 and later XL and 1994 to 1997 1340 Evolution® model motorcycles.(( shanneba from the XLFORUM))   This kit is still being sold by HD as of 12-22-2016.

-  * The nine high performance friction discs and eight spacer discs in this kit replace the original eight paper friction discs and six spacer discs. This kit also replaces the spring plate and diaphragm spring with a higher rate diaphragm spring.(( https://serviceinfo.harley-davidson.com/sip/service/document/2295))
-  * Cautions: Do not reinstall the OE spring plate and diaphragm spring with this kit. Doing so will affect the stacked height of the clutch discs. The spacer discs supplied in this kit must be used with the high performance friction discs. Do not use the original equipment (OE) spacer discs with this kit. Doing so will affect the stacked height of the clutch discs, resulting in clutch slippage.
-  * Installation, refer to the applicable Harley-Davidson Service Manual for installation of friction discs, spacer discs, and diaphragm spring in kit, but follow these important guidelines:
-      * Remove the original eight friction discs, six spacer discs, spring plate, and diaphragm spring from the clutch assembly as described in the Service Manual, and discard.
-      * Replace with nine high performance friction discs, eight spacer discs, and diaphragm spring from kit. Place a friction disc into the clutch shell first, then alternate spacer discs and friction discs.
-      * Kit includes:
-        * Disc set including 9 friction and 8 spacer discs. Part #(38001-04)
-        * 1 Spring, clutch diaphragm Part #(37949-98A)
