E Chain adjustment Turn the rear wheel slowly until you find the position where chain tension is tightest. Put motorcycle on the centre stand and push the chain up pressing with a finger at mid-length of swingarm. The lower stretch of chain must have a slack (fig. 40.1) of 30 mm (ST2) 32 mm (ST4). Chain tension is adjusted as follows: Slacken the nut (1, fig. 40.2) of the wheel spindle, tighten (turn clockwise) or slacken the screw (2) on either side of the swingarm equally to increase or reduce chain tension. If you are slackening the chain, you will have to push the wheel forward. Important Improper chain tension will lead to early wear of transmission parts. Make sure you have adjusted to the same setting marks on both sides of the swingarm. This will ensure perfect wheel alignment. Grease the thread of the wheel spindle nut (1) with SHELL Retinax HDX2 grease and torque nut to 83 Nm. Grease the threads of adjusting screws (2) with SHELL Alvania R3 grease and torque them to 8 Nm. 30 mm (ST2) 32 mm (ST4) fig.40.1 50
