Tighten the crankcase bolts, starting with the periphery of
the crankshaft, then outward.
Replace the washers [A] with a new one.
Torque - Crankcase Bolts (M6): 12 N·m (1.2 kgf·m, 106 in·lb)
Crankcase Bolts (M7): 15 N·m (1.5 kgf·m, 11 ft·lb)
After tightening the crankcase bolts, wipe up the liquid
gasket seeping out around the mating surface, espe-
cially around the area.
Make sure that the crankshaft, driveshaft, and the output
shaft, rotate smoothy (in the neutral position).
If the crankshaft will not turn, probably the crankshaft is
not centered; install the crankshaft jig at the bottom-dead
-center, and tap the appropriate end of the crankshaft with
a mallet to reposition it.

Check to see that gears shift smoothly from 1st to 5th
gear, and 5th to 1st while spinning the output shaft.
Set the shift drum in the neutral position.
Replace the O-ring [A] on the output shaft with new ones.
Install O-ring on the grinding faces of the output shaft
while expanding the O-ring by the hand.
Apply grease to the inside of the output shaft collar [B].
Insert the collar with the groove [C] faces inside.
Replace the circlip with a new one, and install it.
Install the balancer drive gear [A] to the crankshaft so that
