You will need a caliper to get the job done.
Execution sequence
1. Remove the air filter (see «Air filter - removal and installation»).
2. Pulling the tip, pull the clutch cable as much as possible and measure the distance between the leash and the fork lever with a caliper.
3. If the distance is not equal to 27 mm, turn the leash along the thread of the cable tip, achieving the recommended value.
4. Press the clutch pedal three or four times and repeat the measurements. Repeat the adjustment if necessary.
