Bold reference numbers in this section identify parts shown in this exploded view diagram. These parts do not appear in the figures near the text.

Check the wear of the final drive. Visually inspect the front (12) and rear (5) sprockets. If the tooth profile is as shown by the broken line in the figure, change the sprockets.

To check chain (9) wear, stretch the chain and measure 16 links.

If the length (L) is greater than 256.5 mm, change the chain.

Slacken the chain (Sect. D 4, Adjusting chain tension).

Insert the retaining plate (11) on the gearbox secondary shaft (B) and rotate it inside the recess (A) so that the plate holes (11) match the threaded holes in the sprocket (12); position the retaining plate with the rounded corner facing the sprocket.

Tighten the screws (10) to the specified torque (Sect. C 3, Frame torque settings).

Adjust chain tension (Sect. D 4, Adjusting chain tension).

Position the front sprocket cover (13) and tighten the screws (14) to the specified torque (Sect. C 3, Frame torque settings).

Make sure that all pins (1) are securely in place in the flange (2). If not so, unscrew the left-threaded pins, clean the threads and apply threadlocker to the thread with the larger diameter.

Tighten them to the flange to the specified torque (Sect. C 3, Frame torque settings).

Fit the new sprocket (5), hold the pins and tighten the nuts (6) to the specified torque (Sect. C 3, Frame torque settings).

Perform the procedure carefully. If any one pin is not tightened securely fully home into the flange before the nuts are tightened on the sprocket, the sprocket will be installed incorrectly, endangering rider and motorcycle safety.

Grease pins (1) and fit the rear sprocket flange (2) in the rear wheel hub, fit the pins in the relevant rear wheel cush drive rubbers (G).
