Be sure you can hear a difference in the engine sync before bothering with rigging. The tachometers can be inaccurate compared to actual verified by YDS. You may also consider swapping left and right tachs to prove an inaccuracy follows. Can you also see the rpm on the screen or just the gauges?
Both the tach and the Yamaha system show a difference in RPM. I may throw some tape on the engine and measure it as well. They do sound different, but it is only a couple hundred RPM. I am just OCD, so the fact that the throttles don't manually line up with each other at the same RPM gets under my skin.
