Chain backlash check (04_34)

To check the clearance:
•
Shut off the engine.
•
Rest the vehicle on the side stand.
•
Select neutral.
•
Check that the vertical deflection of the bottom section of the chain, measured
at a distance of 320 mm (12.59 in) from the centre of the rear wheel axle
(along imaginary line between centres of front and rear sprockets), is ap-
proximately 48 mm (1.88 in).

•
Move the vehicle forwards to check the vertical deflection of the chain in other
positions; the chain deflection must be constant throughout the entire rotation
of the wheel.
if the clearance is uniform, but greater or less than 48 mm (1.88 in), carry out the
adjustment.
