I'm sorry, I have not asked Mikko's surviving family about any of his property. I think it is still a bit soon after his sudden passing in January . . .
Egg on my face, too. Another good catch, @Speedfrog!
The CIT linked in the Best Relay thread answer are the correct 12V CIT. The Pickers Components noted by Speedfrog have slightly better current ratings, especially for the early V11 Sport's #1 Relay/NC contact position:
Edit: As noted by @Speedfrog, you had the wrong/24V product listed in your post:

[Welldone, @Speedfrog!]
Actually, it is the brake light affected (with the headlight, horn, tach, and charging) by this relay issue. The tail light is on the non-relay circuit with the running/"city" light and the instrument illumination.
I think that is "mis-leading."
When you work through the Decent Tune-up, I suspect you will find the valves off, perhaps one quite tight.
If Shrödinger's cat set your CO at -90, I wonder where he thought he set your TPS . . .
Hmm, maybe not. The MSRP on my 2000 Sport was $11,997US. I got a little discount since I looked like a potential Beta-tester.
This reference gives the MSRP of the 2004 Coppa Italia at $14,590US:

This is classic Relay#2 (complicated by Relay#1) failure. This compromises the tach and the charging reference.What variety of relays are under the seat, @motoguzzikc?
Replace all your relays with the currently available High Current 5-pin referenced in this thread answer:
