Clutch Adjustment

The clutch should be adjusted so that the application of the clutch lever will completely disengage the transmission of power. If the clutch does not completely disengage, the engine will stall when shifting into gear or else the motorcycle will have the tendency to creep even with the clutch lever disengaged.

However, in the other case, if the clutch does not fully engage, the clutch will slip and the motorcycle will not accelerate in response to the acceleration of the engine. In order for the full engine output to be delivered to the rear wheel, it is necessary to have the clutch properly adjusted.

The normal clutch lever free play (2) is measured 0.4-0.8in. (10-20mm) at lever end before the clutch starts to disengage.

Adjust as follows:

  1. Loosen the clutch adjuster locking bolt (4) and adjust with the adjuster (3). Turning the adjuster clockwise (A) will decrease the clutch play and turning counterclockwise (B) will increase the play.
  2. Minor adjustment can also be made with the adjusters at both ends of the clutch cable. Adjustment is made at the drive chain cover end of the clutch cable by loosening the lock nut (6) and turning the clutch cable lower adjuster (5). Screwing the lower adjuster in will increase the play and screwing the lower adjuster out will decrease the play.

       

     

    The adjustment at the clutch lever is made by loosening the lock nut and by turning the circular adjuster (8) Turning in (A) will increase the play and screwing the adjuster out (B) will decrease the play.

  3. After the adjustment has been made, check to see that the clutch is not slipping or that the clutch is properly disengaging according to the following procedure.

After the engine starts, pull in the clutch lever and shift into gear, and make sure that the engine does not stall, nor the motorcycle start to creep. Gradually release the clutch lever and open the throttle, the motorcycle should start smoothly and accelerate gradually.
