My Sport is totally a product of this community, V11LeMans.com. I am so grateful for all of you.
As this thread comes together, I hope to add it to the "How to . . ." for best access as other V11 come into range for the throttle bodies needing attention.
Mine were replaced under warranty (entire rail with injectors and TPS) because they would drip. My excellent dealer told me they do that if you pressurize the system briefly and shut it off. And he was totally right! I was doing this continually: start up the Sport for someone (or just me! ) to listen to the idle and rap the throttle a few times.
Their method was to crab the spineframe to change the throttle body rail, which ain't too bad unless you have added the fussy center frame brace, as I have. Andy York mentioned he intends to loose the left side throttle body and slide the racks out and in. I would like to know more about that.
Also, I recall others who have sealed (O-ringed) and rebushed their shafts. I hope to get those references here as well.
Thanks, again, to all!
