2005 R1200ST - throttle body O Rings / cracked plastic pulleys?

[Ran_Bush]

I noticed the plastic pulleys on the throttle bodies on my '05 R1200ST are cracked. Looking on the interweb, I see that it's a common problem and that the Bing replacement pulleys are a less-expensive option. And the Haynes manual says to replace various O Rings when putting the throttle bodies back together; does anyone have a list of the O Rings that should be replaced when you're "in there" ?

TIA.
