The read distance must be: 9 to 11 mm.

If the drive chain is too tight or too slack, adjust it so that tension reading will fall within specified range.

To adjust the tension remove the rear splash guard (sect. 7 - 13, Removal of the swingarm).

Fit the hook spanner code 88713.1038 Inserting its tooth in the eccentric hub (2).

An incorrectly tensioned chain will lead to accelerated wear of the transmission components.

If the screws (1) are removed, lubricate with specified grease underhead and thread, then tighten the screws (1) to the torque of 35 nm +/- 5% (sect. 3 - 3, Frame torque settings) proceeding with sequence 1-2-1.
