Adjust the clutch push rod with the handlebar adjustment slackened off completely. Screw in the adjuster until there is just perceptible lift on the diaphragm spring and slacken back one full turn, holding in this position whilst the lock nut is tightened completely.
It is possible for the clutch operating lever in the kickstart case to have dropped down between the thrust ball and roller against which the lever lifts and if this has occurred, it will be found that the clutch is inoperative, and it will be necessary to remove the inspection cover which is secured by two screws to the gearbox outer cover, slacken back fully the push rod adjuster and lift the lever back into position before adjusting. ln fig C44 and C45 we show the lever in its correct position and the lever as it may be found if it has dropped.

| Assemble the shims on the crankshaft over the engine sprocket, followed by the spacing collar with the recess outwards.
21 | Fit the rotor key, the inner end of which passes into the recess in the collar.
22 | Ensure that the rotor is free of any magnetic particles it may have attracted whilst dismantled and fit the rotor to the shaft and key, name and timing marks outboards.
23 | Assemble the rotor nut and fan disc washer and with top gear engaged and the rear brake applied fully, tighten the rotor nut fully to 70 to 80 Ibs./ft. (9.678 to 11.060 Kg/m).
24 | Fit the three stator spacers on to the stator mounting studs followed by the stator on which the lead must be outboard at the 5 o-clock position.
25 | Assemble the plain washers and stator securing nuts and tighten to a torque setting of 15 Ibs./ft. (2.074 Kg/m). Check the gap between the stator and rotor which must give a minimum air gap of 0.008 in. to 0.010 in. (0.2032 to 0.254 mm). Any misalignment of the stator mounting studs would account for reduced air gap at any one given point and can only be corrected by very careful slight re-alignment of the studs.
26 | Check that the chaincase sealing band is snugly in position in the recess in the outer face of the inner chaincase with the join in the band at the top then place the outer chaincase in position.

27 | Secure the outer chaincase using the single centre sleeve nut and washer.
28 | In order that the point is not overlooked it is recommended that lubricant is added to the chaincase at this stage.
29 | Refit the left hand foot-rest and brake pedal assembly, securing with three nuts, two washers and the stop lamp lead support bracket acting as the third washer on the bottom stud.
