If one's speedo in his 123 is jumpy, does that affect his CC? Is the CC dependent on the speedo? Mine works and then it doesn't, just like everyone else's. But when it works it seems smooth and stable despite the jumpy speedo. I'd like to have a fully functioning CC, but just focusing on the CC itself ain't gonna cut it if it's speedo-dependent cuz my speedo's f'ud up.
