PERIODIC MAINTENANCE: DRIVE CHAIN ADJUSTMENT
The drive chain should be checked and adjusted every 600 miles. It should be removed, cleaned and lubricated every 2,000 miles.
Place the transmission in NEUTRAL.
Loosen the torque link nut.
Remove the axle nut cotter pin. Loosen the axle nut (A, Figure 19) and the axle adjusting locknuts (B, Figure 19).
Screw the adjusters (C, Figure 19) either in or out as required, in equal amounts.
With the motorcycle on a support block or centerstand, the free movement of the chain, pushed up mid-way between the sprockets, should be 3/4 in. (20mm). See Figure 20.
Rotate the rear wheel to move the chain to another position and recheck the adjustment; chains rarely wear or stretch evenly and as a result, the free play will not remain constant over the entire chain.
If the chain cannot be adjusted within these limits, it is excessively worn and should be replaced.
When the adjustment is correct, sight along the chain from the rear sprocket to see that it is correctly aligned. If should leave the top of the rear sprocket in a straight line.
If it is cocked to one side or the other (Figure 21), the rear wheel is incorrectly aligned and must be corrected by turning the adjusters counter to one another until the chain and sprocket are correctly aligned.
When the alignment is correct, readjust the free play as described above and tighten the adjuster locknuts and axle nut securely.
