NOTE
Split the crankcase again, measure each clearance between the bearing insert and journal [B] using plastigage (press gauge).
Crankshaft Main Bearing Insert/Journal Clearance
Standard: 0.010 0.034 mm
(0.0004 0.0013 in.)
Service Limit: 0.06 mm (0.0024 in.)
If the clearance is within the standard, no bearing replacement is required.
If the clearance is between 0.035 mm (0.0014 in.) and the service limit (0.06 mm, 0.0024 in.), replace the bearing inserts [A] with inserts painted blue [B]. Check insert/journal clearance with the plastigage. The clearancemay exceed the standard slightly, but it must not be less than the minimum in order to avoid bearing seizure.
If the clearance exceeds the service limit, measure the diameter of the crankshaft main journal.
Crankshaft Main Journal Diameter
Standard: 34.984 35.000 mm
(1.3773 1.3780 in.)
Service Limit: 34.96 mm (1.3764 in.)
If any journal has worn past the service limit, replace the crankshaft with a new one.
If themeasured journal diameters [C] are not less than the service limit, but do not coincide with the original diameter markings [D] on the crankshaft, make new marks on it.

Technical Information-Power Mode
The rider can choose from three engine power modes to suit their preferences
and road conditions.
The FI ECU controls the engine power by adjusting fuel injection, air intake,
and ignition timing. It
enables three-mode selection: Full Power (Mode F), Middle Power (Mode M), and
Low Power (M ...
Battery Removal

section in the GENERAL INFORMATION
chapter).
Turn the ignition switch to “OFF” and
disconnect the (–) cable from the battery.
Remove the red cap form the (+) terminal,
and disconnect the (+) cables
from the battery.

Piston Ring Groove Width Inspection
Measure the piston ring groove width.
Use a vernier caliper at several points around the piston.
