There are several crucial steps that must be understood and performed to ensure your Radius X clutch

will function properly. Failure to properly install, break-in and maintain your clutch components will

result in premature wear or failure.

New Friction Disk Break-In Procedure

Failure to follow the break-in procedure and oil filter inspection process could cause motor oil

delivery failure which can result in motor failure, serious injury, or death.

DO NOT install a new set of friction disks and ride without following the break in procedure and

oil screen inspection process found in the installation manual.

o Soak new friction disks in oil

o Install new friction disk and set the installed gap

o Check and verify free play gain

o Perform the break-in procedure found in the installation manual

o Follow the oil filter inspection process found in the installation manual

Clutch Lever Optimization

There are some brands of bikes that ship with stock adjustable reach levers. It is important

when setting up any adjustable reach lever to adjust the lever position first, and then adjust Free

Play Gain second. If you were to do it the other way around, you could alter the FPG setting

while changing the reach of the lever, which could cause poor performance and early clutch

wear.

Rekluse offers an adjustable reach lever upgrade for most cable actuated models. This optional

upgrade provides the user with the ability to optimize the clutch lever position for your hand size

and personal preference. This will maximize lever feel for each individual.

See the lever optimization section in the manual for more details.

Checking Free Play Gain

Check free play gain at the start of each ride. Details on how to check free play can be found in your

installation manual.

Understand how to properly check for free play gain

o Do not ride if you cannot verify free play gain

o Clutch may seem to work fine but could be slipping excessively

If you cannot detect free play gain, reset the installed gap

Page 11 Failure to inspect the basket and replace if necessary could result in death, serious injury, and/or property damage. Install ALL the Rekluse basket sleeves into the basket slots. Make sure the sleeve tabs sit against the inside the basket, then push the sleeves down until they contact the bottom of the tang slot.

Note: When seated in the basket, the sleeves may stick slightly above or below flush with the top of the basket. This is normal. Install all the basket sleeves Notes for Clutch Pack Installation: · The clutch pack will be replaced with all new frictions and steel drive plates.
Page 13 · Some OE basket have “half slots” at the top of the basket tangs. Rekluse products require the entire clutch pack be installed into the MAIN (deeper) basket slots. Installing the clutch pack and EXP disk in the “half slots” will cause performance issues.
Page 14: Pressure Plate Installation
1. Add a light film of oil between the lining plate and pressure plate (this will help the plates stick together for ease of installation). 2. Place the new steel lining plate onto the Rekluse pressure plate by lining up the index tabs and slots. Do not reuse the old lining plate.

8. Reinstall the OE oil plug if it was removed during disassembly. 9. Torque clutch cover bolts to OE specification. Reinstall clutch cover gasket or O-ring SET THE INSTALLED GAP AND CHECK FREE PLAY GAIN It is very important that you understand how to set the installed gap in your new clutch, and be able to verify the installed gap by checking Free Play Gain.
Page 19 The “installed gap” is the free space in the clutch pack when the EXP disk is disengaged (collapsed). This gap allows the clutch to spin freely until the engagement RPM is reached and the EXP disk expands to close the gap and apply pressure to the pressure plate, which in turn drives the motorcycle forward.
Page 20: Step 1: Set The Installed Gap
Setting the installed gap and checking Free Play Gain is a 4- step process. It is important to follow each step to ensure that your new clutch functions as designed. Step 1: Set the installed gap Do not ride your bike without the adjusting the installed gap.
Page 21: Step 2: Learn How To Check Free Play Gain
Free Play Gain is different from the “normal” free play you are used to with your stock clutch. With the Rekluse auto clutch, Free Play Gain is the result of the EXP disk expanding and lifting the pressure plate to engage the clutch.
Page 22 closes the installed gap. The amount of Free Play Gain you feel in the lever corresponds to the amount the pressure plate has been lifted by the EXP disk expansion. Checking Free Play Gain allows you to externally monitor the installed gap so you can know when to make an adjustment if the installed gap is too large or too small.
Page 23: Two Ways To Check For Free Play Gain
Gain The following steps explain 2 ways to check Free Play Gain. One way uses the rubber band Rekluse includes in the clutch kit, and one uses your hand. You can use either method to check for Free Play Gain.

Free Play Gain. Failure to do so may result in the bike lurching forward, and loss of control and/or injury may result. A Rekluse auto-clutch can make your motorcycle appear to be in neutral when in gear, even when the engine is running and clutch lever released.
Page 25 c) While holding the top end of the rubber band against the handlebar, stretch the band downward, then loop it through itself. d) Pull the band through the loop, then attach it to the outside end of the clutch lever. This will take up the initial free play (slack) and put the lever in a...
Page 26: The Hand Method
The Hand Method Use the hand method to check Free Play Gain before the start of every ride for optimum performance and longevity of your new clutch. a) Before you begin, place the bike in NEUTRAL, start the engine and let it warm up for 2-3 minutes to idle down and warm up the engine oil.
Page 27: Step 3: Break-In The New Clutch
Step 3: Break-in the new clutch Once you install your new clutch, it is important to break it in. A series of roll-on starts are used to break in the clutch. Follow these procedures for breaking in your clutch and any time new friction disks, EXP bases, Teflon pads, or wedges are installed.
Page 28 4. With the bike idling in first gear, slowly apply throttle to begin moving. 5. Without using the clutch lever, accelerate moderately to 10 roll-on starts approximately 5,000 RPM to fully lock up the clutch and come to a complete stop. Repeat 10 times.
Page 29: Step 4: Adjust The Installed Gap And Recheck Free Play Gain
Note: Your clutch pack will expand with heat, so final adjustment to Free Play Gain should be made when the bike is warm. Remember not to ride without sufficient Free Play Gain. 4 strokes only: It is normal for some clutch debris to be produced during break in.

These are best viewed in color by viewing this install document from www.rekluse.com/support. Drive Plates – If the clutch pack is getting high amounts of heat, purple, blue, or black color can be seen on the drive plate teeth.
Page 34 Friction Disks – Due to the dark color of the friction material, the friction disks will appear almost black as soon as they are put in oil. During inspection, look for glazing of the friction material. Glazing will appear shiny and feel like glass, even after oil is cleaned from the friction disk.
Page 35: Troubleshooting
For bike models that have noise, here are some recommendations to reduce or eliminate it: · Change the oil: Rekluse recommends that you have fresh, clean JASO-MA or JASO-MA2 rated oil for best clutch performance. Dirty or old oil can make the clutch more likely to squeal or chatter.
Page 36: Exp Tuning Options
You can tune the engagement RPM of the EXP disk by changing the spring configuration. The EXP disk comes set with the recommended “Medium” setting from Rekluse. For other EXP tuning options, see the Setup sheet. 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.
