I posed the TPS gap question to a friend of my brother who was a Guzzi dealer / Guzzi Race team owner in the 90s and early 2000s (now vintage car builder/racer), and here is his reply:
"🤣 Marelli FI if l remember.
Lowest cost supplier….
Design change of the sensor or throttle body or both….
Both are sealed for water intrusion by design. Air for TB. Water for electrical connection on the Tps.
could always tape off and insert some black RTV. "
Was hoping his input might be a bit more enlightening, like "adds more air for intake by design", but seems to confirm what you were all thinking - just not one of Guzzi's better moments in parts supply integration...
