My upper pivot seems to have acceptable
spring action right now so I won’t take apart the B pivot again, not yet.
Turns out I was able to loosen the “B’” adjustment screw and able to see the upper pulley move in closer to the cassette cogs. I loosed the screw
too much to where the upper pulley was making contact with the smaller cogs. I tightened the B screw again just enough that it pulled the upper pulley away from these small cogs and allowing better chain engagement from what I see. I did some test laps around my neighborhood with a few
light pressure standing drills and it seems as if the shifting is drama free. I’ll be departing on my bike club ride and plan to ride about 45 miles tonight. I will report back later tonight on how it goes.
Next frustrating mechanic job: sorting my Shimano Flight Deck bike computer! I keep wishing that the classic & vintage Shimano mechanics out there would publish a thread or a guide to troubleshooting the Flight Deck system for road bikes.
