Clutch drag when hot

Hi,
Thoughts & suggestions welcomed. My LI with a SIL 200 motor has a habit of clutch drag when the motor is well warmed-up. Clutch cable adjustment with the motor cold is right but as the motor gets warm I get too much free movement on the clutch lever and the associated drag.
I recently replaced the original SIL friction plates with BGM and changed the oil to Maxima E85 but the issue remains.
Regards,
Simon.
