a. Turn the crankshaft counterclockwise.
b. When piston #1 is at TDC on the compres-
sion stroke, align the TDC mark
a on the
pickup rotor with the crankcase mating sur-
face
b.
TDC on the compression stroke can be found
when the camshaft lobes are turned away from
each other.
c. Measure the valve clearance with a thick-
ness gauge

If the valve clearance is incorrect, record the
measured reading.

Measure the valve clearance in the following
sequence.

NOTE:

Refer to “ASSEMBLING AND ADJUSTING
THE ENGINE – CYLINDER HEAD AND CAM-
SHAFT” in chapter 5.

Lubricate the camshaft bearings, camshaft
lobes and camshaft journals.

First, install the exhaust camshaft.

Align the camshaft marks with the camshaft
cap marks.

Turn the crankshaft counterclockwise several
full turns to seat the parts.
g. Measure the valve clearance again.
h. If the valve clearance is still out of specifica-
tion, repeat all of the valve clearance adjust-
ment steps until the specified clearance is
obtained.

CHANGING THE COOLANT
1. Remove:

bottom cowlings

side cowlings
Refer to “COWLINGS”.

rider seat
Refer to “SEATS”.
2. Remove:

coolant reservoir tank

coolant reservoir hose
3. Disconnect:

coolant reservoir cap
1
4. Drain:

coolant
(from the coolant reservoir tank)
5. Remove:

radiator cap
1
A hot radiator is under pressure. Therefore,
do not remove the radiator cap when the en-
gine is hot. Scalding hot fluid and steam may
be blown out, which could cause serious in-
jury. When the engine has cooled, open the
radiator cap as follows:
Place a thick rag or a towel over the radiator
cap and slowly turn the radiator cap coun-
terclockwise toward the detent to allow any
residual pressure to escape. When the his-
sing sound has stopped, press down on the
radiator cap and turn it counterclockwise to
remove.
The following procedure applies to all of the
coolant drain bolts and copper washers.
6. Remove:

coolant drain bolts
1
(along with the copper washers)

3. Replace:

blown fuse
a. Set the main switch to “OFF”.
b. Install a new fuse of the correct amperage
rating.
c. Set on the switches to verify if the electrical
circuit is operational.
