Tracer 900 Throttle Bodies and Spark Plugs

2019 Yamaha Tracer 900 (Base Model) 

I just completed the second check of my throttle bodies sync, using my Digi Sync Vacuum Manometer (See July 2020 Original Post), and spark plug replacement. I'm performing this maintenance at 6,000 miles, which is 2,000 miles short of the intervals, because I'm launching on a trip that will extend well beyond the interval threshold. 

I have some video on this maintenance that Tracer owners may find useful.

Not to spoil it, but the throttle bodies were in reasonable sync at this 6,000 milestone as was the case during the first synch check.
