I have a ticking noise from the upper primary that is driving me nuts. The sound appears to be coming from the upper primary right above the compensator. When you crank the bike, the ticking starts when you start throttling up a bit. When riding the bike, the ticking seems to only be heard when trying to maintain speed. When you throttle up under it seems to go away, and when you let off completely it goes away. Has anyone had this type of problem, or any insight on what it might be? I've done a lot of research on several forums, and mine seems to be a bit different than what others have experienced. You can hear this noise good when you use the screwdriver listening method at the bolt above the compensator.
