DRIVE CHAIN ADJUSTMENT
The drive chain must have adequate free play so it can adjust to swing arm movement. Too little free play can cause the chain to become tight and cause unnecessary wear to the components.
Too much free play can cause the chain to derail.
- Support the motorcycle so it is vertical. The rear wheel can be on or off the ground.
- Measure the free play in the bottom length of the chain (Figure 39) as follows:
- Place a tape measure so it is stable and vertical below the chain midpoint.
- Press the chain down and note where a chain link-pin aligns with the tape measure. Note the measurement.
- Push the chain up and note where the same link pin aligns with the tape measures. Note the measurement.
- The difference between the two measurements is the chain free play. Required free play is 40-50 mm (1.6-2.0 in.).
- If necessary, adjust the free play on E and S models as follows:
- Remove the cotter pin from the axle nut, and them loosen the nut (Figure 40).
- Position both numbered chain adjusters (Figure 41) so the free play is correct. Both adjusters must be set identically and locked against the adjusting post. If increasing free play, push the wheel forward to take the play out of the adjusters.
