DRIVE CABLE ADJUSTMENT
1. Disconnect spark plug wire.
2. Remove the bag (item 5) and transmission cover (item 21) which will allow the transmission drive lever arms to be
visible.
3. Loosen the two nuts on the barrel of the cable going into the drive levers.
4. Tension on the drive lever is reduced when the barrel of the cable is moved upwards towards the lever and tension is
increased when the barrel is removed further away from the lever. NOTE: Moving the barrel too much in either direction
will result in the drive lever constantly being engaged or not engaging at all.
5. When engaging the drive levers check the exposed transmission to make sure that the arms are properly engaging and
returning to a disengaged position.
6. Reattach the transmission cover and bag.
7. Reconnect spark plug wire.
8. Check for proper operation.
