Riding yesterday, cc would sometimes set and sometimes not. Didn't seem to matter what gear, speed, etc. When cc worked, all functions seems to work correctly(throttle roll, clutch, brakes would turn off cc, increase/decrease cc worked, etc). The only thing that I can think of is I performed a clutch cable adjustment prior to riding. Is there anything simple that I should look at and consider?

 

Mine played up when the rear brake light switch started to become faulty.
Check your brake light is not staying on occasionally by pressing the rear brake lever a few times in the driveway. If it is or if you run your hand over the switch and feel a film of brake fluid leaking then get it replaced.

 

It was the clutch cable adjustment... I had it a touch too tight.
