Rekluse EXP for Harley-Davidson Big-Twin – Cable-Actuated Page 6
EXP TUNING OPTIONS
Included are spring options to tune the engagement RPM of the EXP friction disk. The EXP friction disk comes
set with the recommended “Medium” setting from Rekluse. See the following chart for settings.
Adjusting the engine idle speed to match your engagement setting is important and greatly affects the overall
feel of how the EXP disk engages. To prevent freewheeling and maximize engine braking, set the idle so there
is a slight amount of drag while the bike is idling in gear and warmed up. The idle should not be so high as to
move the bike forward in gear with the throttle closed. However, with a small opening of the throttle the bike
should move forward.
It is NOT necessary to disassemble the EXP halves to change springs! To change springs, remove 3 of the
¼-turn pins from one side of the EXP, replace springs, and re-install ¼-turn pins. Next, flip the EXP disk over
and repeat on the other side if necessary. To maintain even pressure when using two different color spring
sets, install one color set of 3 on one side of the EXP and the remaining color set of 3 on the other side.
Bearing pads may fall out or be stuck to the ramp surfaces of the EXP bases as you disassemble
the EXP. Operating the clutch without the pads in place will cause part damage or failure.
Ensure all pads are correctly placed into wedge pockets using gentle pressure to avoid damage to the pad
surfaces before reassembling the EXP. Properly seated pads will be secured in place once the EXP is
reassembled.
