Adjusting the chain tension
This this the extract from the workshop manual. I hope this helps. ( sorry would not let me upload the images)
Adjusting the chain tension
Move the bike slowly so as to find the position where chain upper section is more tensioned.
Raise bike on side stand.
With the motorcycle on its side stand, measure chain tension as follows: press with a finger in the centre of the bottom run of the chain, release it and measure the distance between the centre of chain link pins and the swingarm aluminium part.
Value (A) must be:
- (72 ÷ 74) mm (BASE version)
- (72 ÷ 74) mm (SP version)
- (59 ÷ 61) mm (HYPERSTRADA version)
- (57 ÷ 59) mm (HYPERSTRADA version with LOW SEAT)
Slacken off the two screws (1) that secure the rear wheel hub to the swingarm.
Fit the pin wrench (A) part no. 88713.1038 inserting its tooth in the eccentric hub (2).
Rotate the eccentric hub (2) to obtain the correct chain tension.
Turn counter clockwise to tighten the chain; clockwise to loosen (from chain side view).
Important
An incorrectly tensioned chain will lead to accelerated wear of the transmission components.
If screws (1) are removed, smear under head and thread with the recommended grease, then, tighten them to a torque of 31 Nm ±5%, following the sequence 1-2-1.
Warning
Correct tightening of swingarm screws (1) is critical to rider and passenger safety.
