NOTE: Read the instructions carefully before proceeding with the actual installation.

NOTE: To avoid accidental start up of vehicle during the installation, remove both battery

cables & the battery. Securely block motorcycle in an upright position. Different models will

require the removal of shifting levers, foot pegs, etc. Remove whatever is necessary to

accomplish the installation per your OE service manual.

(On 2007 & some 2008 models, you must replace the alternator rotor with part # 30041-08)

Using your OE manual, strip the motorcycle down to

what is shown in Figure 1.

Remove the bearing race from the transmission main-

shaft using JIM’S part # 34902-84.

Remove alternator rotor and check sprocket shaft oil

seal. The steel back on this seal should face away from

the engine when using a primary belt drive which will

keep oil from leaking into belt drive. (Use seal HD part #

12068).

NOTE: Although the motorplate will come pre-assembled

from the factory, we are including the assembly steps if

the need arises to re-assemble it.

Install the 6 hollow dowels into the motorplate (See

Figure 2)

Install the motorplate spacers (2 round spacers with

hollow dowels on trans side, one starter spacer with

engraved logo and 2 split hollow dowels on the starter

side, and one alternator spacer) onto the hollow dow-

els already installed on the motorplate. (see figure 4).

NOTE: The round spacers have a beveled edge on

one end and a crisp edge on the other end. The

beveled end goes toward the trans and the crisp edge

goes up against the motorplate. (See figure 4).

Install the dowels using the method as per figure 3.

Use a 5/16-18 x 3” bolt, 5/16” flat washer & 5/16-18 nut

to install all the hollow dowels except for the lower front

mp bolt hole which will require a 1/4-20 x 3” bolt, 1/4”

flat washer & 1/4-20 nut.

Apply two drops of blue threadlocker to the two 5/16-18 X 1 1/2” SHCS bolts and then attach the starter spacer to the motorplate by threading the two bolts from starter side of motorplate spacer into motorplate and torque 25 ft.lbs. (See figure 5). Figure 5 The motorplate is now ready to install (See figure 6). NOTE: There is a threaded plug in the center of the motorplate. If you intend to use Rivera Primo’s MidControls (part # 2084-0504) , this plug should be removed.

Now, using the supplied (4) 1/4-20 X 2 1/2” (motorplate to motorcase) & (2) 5/16-18 X 2 1/2” (motorplate to motorcase) & (3) 5/16-18 X 2 1/4” (motorplate to transmission) bolts, secure the motorplate to the transmission and motorcase making sure to use 2-3 drops of blue threadlocker on each bolt. Then torque the 1/4-20 SHCS to 98-102 in. lbs & 5/16-18 SHCS to 28-32 ft. lbs. (See figure 10). Figure 10 You are now ready to install the belt drive on the shafts.

Figure 16 Figure 15 Assemble the belt on the front & rear pulley and holding them as a unit, slide them onto the motor sprocket shaft and transmission mainshaft at the same time. (See figure 15). It may be necessary to work the pulleys a little bit at a time to walk them onto the shafts. (See figure 16 & 17). Figure 17 Put 4-5 drops of blue thread locker on front pulley bolt then insert the bolt and cup washer into the front pulley and torque to specs found in your OE manual.(See figure 18).
PAGE 5
Assemble the clutch in the clutch shell by inserting the .120” steel drive plate first. (See figure 21) Follow that with a friction, then alternate the steels and the friction plates never having two steels together or two frictions together. End with a steel plate. Figure 21 Install the pressure plate with the side stamped with the word ‘OUT’ facing away from the motorcycle. Now install the diaphragm spring and the spring retainer (The word ‘OUT’ stamped into the pressure plate faces away from the bike).

Figure 25 Figure 26 The outer guard stand-offs have the studs pre-installed. (See figure 25) Should the need arise to remove the studs from the stand-offs, be sure to re-install them with RED thread locker and there must be at least 5/8” of stud outside of the aluminum stand-off. (See figure 26). To install the stand-offs, apply 2-3 drops of RED thread locker on each exposed threaded stud (See figure 26).
