The drive chain clearance must between the 30 to 45mm interval, at the half way between the
drive sprocket and rear sprocket.
To adjust the tightness, place the motorcycle on the side stand.
― Loosen the axle nut (1);
― Loosen the fixing nuts (2) on the both sides;
― Adjust the adjuster screws (4) until the clearance of drive chain is within
specifications. Simultaneous, ensure that the rear sprocket is aligned with drive
sprocket;
― Check if the chain tensioners (3) are aligned with the reference marks on swing arm.
If they are not visible, measure the distance between tensioners and swing arm end;
― Tight securely the axle nut and the fixing nuts;
― Verify the chain clearance after the procedure;
― Lubricate and adjust if necessary.
Excessive tension of the drive chain will produce additional load on the
components. Aside from resulting on premature wear, the drive chain may break.
Excessive drive chain clearance can result in chain jumping off from the chain
sprockets. In this case, the chain can also block the rear wheel or damage the
engine.
In both cases, the rider can lose control of the motorcycle.
