Cees, I will agree with you.
I am a long-time member of the Honda CBX Owner's Association. This bike is a late 70s/early 80s motorcycle with an in-line six and six carburetors.
For a long time, there have been discussions among members to convert the bike to FI.
Several attempts have been made. Some more, some less successful. The major challenge is the control mapping and the proper air flow metering. Also, which injectors to select.
The consensus is, if you need to do it, because you think it can be done, do it.
It will not improve rideability in most cases and it will not increase the value of a vintage classic.
On the other end of the spectrum, Kawasaki had a 6-Cylinder, the KZ1300. From 1979 through 1983 it was carbureted (3 double barrels) and in 1984, it was changed to the "Voyager" and turned FI. Many important parts are no longer available and hard to service. Consequently, owners go back and convert to carbs.
I realize, our cars are FI and changing to a more modern, ECU controlled FI should be relatively easy, but I am afraid it is not.
