• Measure the electrical resistance between terminals ➀ and ➁.
• If the measurement is out of specification, replace the speed sensor 1. P.11-55
CAUTION
Check the tightening torque of the engine speed sensor 1. If the sensor is insufficiently tightened, it may not produce signals.

Fitting side cover
• Apply an even, unbroken bead of sealant A to the side cover 5.
• Fit the side cover 5 onto the crankcase within 3 minutes of applying the sealant A.

CAUTION
• Ensure that the sealant application surface of the side cover 5 is clean before applying sealant.
• When fitting the side cover 5, hold it firmly in position to prevent spreading the sealant.
• After fitting the side cover 5, wait at least an hour before starting the engine.
• Apply a new bead of sealant A whenever the mounting bolts of the side cover 5 have been loosened.

Camshaft assembly
[Removal]
• When removing the camshaft assembly 6, take off the side cover 5 and support the camshaft by hand.
• Remove the bolts A from the camshaft gear holes, then slowly remove the camshaft assembly 6.
CAUTION
Take care not to damage the camshaft bushings 12 to 15 when removing the camshaft assembly 6.

[Installation]
• Before installing the camshaft assembly 6, measure the end play between the thrust plate 9 and camshaft 11.
• If the measurement exceeds the specified limit, replace the defective part(s).
• With the alignment marks lined up on the camshaft gear 8 and No. 2 idler gear, fit the camshaft assembly.

• Fit the camshaft gear 8 onto the camshaft 11 in the direction illustrated.
• Do not forget to fit the key 10.

Inspecting camshaft
(1) Cam lift
If any base circle-to-lobe height difference is less than the required value, replace the camshaft 11.

NOTE
Since the cams are tapered, they must be measured at the position A shown in the diagram.
B: Lobe height
C: Base circle diameter
D: Front of engine
(2) Camshaft bend
Support the camshaft 11 at its No. 1 journal E and No. 4 journal F, then take measurements at the No. 2 journal G and No. 3 journal H. If either measurement exceeds the specified limit, replace the camshaft.

NOTE
Turn the camshaft 11 through one revolution. One-half of the dial indicator reading represents the camshaft's bend. to Camshaft and camshaft bushings
[Inspection]
If any clearance exceeds the specified limit, replace the defective part(s).
NOTE
Measure the camshaft bushings 12 to 15 with the camshaft installed in the crankcase *.
