○Remove a crankcase left-side cover.
◇Turn both A and B counterclockwise to remove
them.
◇Set the flywheel and cam sprocket so the “T”
and “O” marks on them respectively face
forward. And set the timing marks to be in
contact with the cylinder head surfaces.
And turn the flywheel counterclockwise so it
meshes with each notch.
○Remove a cam sprocket.
◇Remove a hex bolt next to the change-pedal
shaft. (As the tensioner which is holding the c
am chain slackens, it becomes easy to install
the cam chain.)
◇Holding the flywheel, remove two hex bolts on
the cam sprocket by turning them
counterclockwise.
◇Remove a cam sprocket from the cam shaft.
◇Detach the cam chain from the cam sprocket, and
take out the cam sprocket.
◇Detach a dowel pin fixed in the center of the
camshaft.
(Keep the dowel pins for re-use.)
◇Remove a stopper plate, rocker arm and rocker
arm shaft from the cylinder head.
◇Install the camshaft included in the Kit.
Apply clean engine oil to the camshaft and its
bearings. Even if you cannot easily fix the
camshaft, fix it manually without striking it with
a hammer.
◇Attach the dowel pins, originally attached to
the stock camshaft, to the supplied camshaft.
◇Install the rocker arm, rocker arm shaft and
stopper plate which you have just removed from
the cylinder head.
Stopper plate bolt : 12N・m (1.2 kgf・m)
※If you fail to install the rocker arm shaft onto the
rocker arm, loosen the adjusting screw on the
rocker arm.
○Installation of cam sprocket.
◇Align the “T” mark on the flywheel with the
notch on the crankcase, and set the piston at
the compression top dead center position.
◇et the shaft so the cam top faces the piston
when the cam sprocket bolt hole is turned
toward the notch on the cylinder head.
This arrangement places the cam shaft at TDC
(Top Dead Center) on the compression stroke.
◇Set the cam sprocket so its “O” mark faces the
front. And after meshing the timing marks with
mating surface of the cylinder head cover, place
the cam chain on the camshaft.

○Valve timing adjustment and tappet
clearance adjustment.
◇Give the crankshaft two clockwise turns.
And check that all the alignment marks are
meshing with one another, with the “T” mark on
the flywheel, the notch on the crankcase and
the timing sprocket mark facing the front.
◇Holding the flywheel, tighten up two cam
sprocket bolts.
Tightening torque : 9 N･m (0.9 kgf･m)
◇Install the just-removed bolt next to the change
pedal shaft, and tighten it up.
Tightening torque : 10 N･m (1.0 kgf･m)
◇While tightening a rocker arm’s tappet adjusting
screw, tighten the tappet adjusting nut to the
extent that you can pull out a thickness gauge,
placed between the tappet adjusting screw and
the valve stem end, feeling only a little resistance.
IN:0.10mm
EX: 0.12 mm
Fit together the crankcases with a 14mm box
wrench and medium-sized long joint.
◇After adjusting the tappet, give the flywheel two
turns counterclockwise by hand, and then, align
the “T” with “O” marks.
◇Check if there is any change in the tappet
clearance. If the clearance has not changed, there
is no need to readjust it. However, in case there is
a change, readjust the clearance.
Repeat this readjustment until you get a right
tappet clearance.
