The fluctuating idle has not recurred for over three weeks since removing the stack of bungee cords from the under-seat compartment. I have been riding my bike almost every day over that time.
Prior to removing them, the fluctuating idle would occur intermittently two or three times over a 30 minute ride.
It is the lack of any more fluctuating idle problems over the past three plus weeks that makes me think there is nothing mechanically wrong with my bike. The idle has always been smooth during that time.
To confirm that the stack of bungee cords are involved, in a few days I will put them back in the storage compartment and try to reproduce the idle problem.
BOTH ends of BOTH battery cables checked?
Vacuum lines intact?
Check all the hoses, including 4 way and 5 way vacuum fittings?
A crack would suck air and increase idle...unless the crack got bigger than it would decrease idle.
Be good to replace with brass, but finding more than a 3 way would be a challenge.
The 5 way (part 18) is 17201-MCJ-003 ($7 list)
The 4 way (part 19) is 17201-MCZ-003 ($5.60 list)

Not stating that this is the problem, but worth checking.
