Rivera Primo Centri-Force - Chain Drive - Manual

ADDITION TO CENTRI-FORCE TM INSTRUCTIONS
for CHAIN DRIVE APPLICATIONS
1108-0047
The Centri-Force™ with chain drive basket is shipped from our factory ready to install.
Depending on the idle rpm of your engine and individual needs, the way it is setup from
the factory should get you started.
INSTALLATION
Installation of the Centri-Force™ on chain drive applications is easy. First drain and then remove
the outer primary cover. Next remove the compensator nut and the clutch hub nut and the chain
adjuster nut. Remove the complete chain drive assembly. Remove the Centri-Force™ centrifugal
pressure plate by removing the (12) 10-32 x ¾" bolts. (If you remove any clutch plates, they
must be re-installed in the exact same order). Replace the OE clutch basket with your new
Rivera Primo clutch basket assembly minus the Centri-Force™. Re-install the primary drive and
secure the comp assembly, chain adjuster and clutch basket with the proper fasteners tightened
to OE specs. Now re-install the Centri-Force™ with the same (12) 10-32 x ¾" bolts. After you
install the Centri-Force™ clutch, thread the adjuster screw in the center hole.
ADJUSTMENT
CABLE CLUTCH
Turn out the center adjuster screw. Now back off on the clutch cable adjuster until the clutch
lever touches the handlebar grip. Tighten the clutch cable adjuster jam nuts. Hold the clutch
lever against the handle bar and with the other hand, screw in the center adjusting screw until
you feel it push against your hand thru the lever. At this point, lock down the center adjusting
screw jam nut.
Start the bike, making sure the transmission is in neutral. Rev the motor up to around 2000-2500
rpm's, the lever should move out away from the handlebar. At no time should the lever extend
out all the way from the handlebar, you must have free play at the end of the lever travel
just like a normal clutch. At idle and low rpm, there will be very little clutch pull.
