4. INSPECT DIAPHRAGM SPRING FOR WEAR
Using calipers, measure the diaphragm spring for depth
and width of wear.
Maximum: Depth 0.6 mm (0.024 in.)
Width 5.0 mm (0.197 in.)
If necessary, replace the clutch cover. 3. REMOVE RELEASE BEARING, FORK AND BOOT
FROM TRANSAXLE
(a) Remove the bearing assembly together with the fork,
and then separate them.
(b) Remove the boot.
INSPECTION AND REPAIR OF CLUTCH
PARTS
1. INSPECT CLUTCH DISC FOR WEAR OR DAMAGE
Using calipers, measure the rivet head depth.
Maximum rivet depth: 0.3 mm (0.012 in.)
If a problem is found, replace the clutch disc.
3. INSPECT FLYWHEEL RUNOUT
Using a dial indicator, check the flywheel runout.
Maximum runout: 0.1 mm (0.004 in.)
If runout is excessive, replace the flywheel. 2. INSPECT CLUTCH DISC RUNOUT
Using a dial indicator, check the disc runout.
Maximum runout: 0.8 mm (0.031 in.)
If runout is excessive, replace the clutch disc.

(b) Check the valve seating position.
Apply a thin coat of Prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do
not rotate the valve.
(c) Check the valve face and seat for the following:
wIf blue appears 360° around the face, the valve is con-
centric. If not, replace the valve.
wIf blue appears 360° around the valve seat, the guide
and are concentric. If not, resurface the seat.
wCheck that the seat contact is in the middle of the valve
face with the following width:
1.0 ± 1.4 mm (0.039 ± 0.055 in.) (d) Check the valve overall length.
Standard overall length:
Intake 100.60 mm (3.9606 in.)
Exhaust 100.45 mm (3.9547 in.)
Minimum overall length:
Intake 100.1 mm (3.941 in.)
Exhaust 100.0 mm (3.937 in.)
If the overall length is less than minimum, replace the
valve.
(e) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, resurface the tip with a
grinder or replace the valve.
NOTICE: Do not grind off more than the minimum.
12. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.

(b) Check the valve seating position.
Apply a thin coat of Prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do
not rotate the valve.
(c) Check the valve face and seat for the following:
wIf blue appears 360° around the face, the valve is con-
centric. If not, replace the valve.
wIf blue appears 360° around the valve seat, the guide
and face are concentric. If not, resurface the seat.
wCheck that the seat contact is in the middle of the valve
face with the following width:
1.0 ± 1.4 mm (0.039 ± 0.055 in.) (d) Check the valve overall length.
Standard overall length:
Intake 96.1 mm (3.783 in.)
Exhaust 96.2 mm (3.787 in.)
Minimum overall length:
Intake 95.6 mm (3.754 in.)
Exhaust 95.7 mm (3.768 in.)
If the overall length is less than minimum, replace the
valve. (c) Check the valve head margin thickness.
Standard margin thickness: 1.0 mm (0.039 in.)
Minimum margin thickness: 0.5 mm (0.020 in.)
If the margin thickness is less than minimum, replace
the valve.
(e) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, resurface the tip with a
grinder or replace the valve.
NOTICE: Do not grind off more than the minimum.
12. INSPECT AND CLEAN VALVE SEATS
(a) Using a 455 carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.
