Got a '79 xs400. The tach will slowly flutter up to 3k when started but will stay there, no more, and no less. And the speedometer will also flutter up to 30k (I live in canada so kph here) when moving but stays there until I stop. How do I fix/adjust these? The obviously work, but I need them to work properly. Can't find any info in the service manual.
