The Diamond side plate is directional and a light press fit. The plate on the right is "used", so now the plate will easily press over the pins. That's why the plates are only designed to be used once, I suppose. You could lose a master link, like you could lose a "used" piston pin clip (somewhere between BTDC and TDC.
A new plate is directional, because if you flip the new plate over, it will push further on the pins, installed on the flip side.
The in side of the plate has a lighter circle stamp.
The out side of the plate a heavier stamping.

Grind the peen off all four link pins, flat to the side plate. You'll be pushing a single pin from the link with this tool, and you can't center the drift pin on an uneven peen.

Imo, the correct tools for the job enhance the Zen moments of motorcycle maintenance.
It would be irresponsible not to show the direction of the master link.
This was a 104 link chain. Now it's 63-3/4" long (the same as the '49-57 Spare Parts Catalog calls out for a 63-3/4" length, and 102 links), laid flat with the links compressed. 102 links still work when using a 26-T transmission sprocket.
This is V-Twin frame #1107 from 1997. I thought maybe the transmission mounts and axle plates might have been out of alignment. It appears that everything is correct. Thanks to Don @ Corbin Gentry that oversaw the adjustments. This Pan has been 10+ years in the making and I'm getting closer. Sure nice when it all fits together.
