My 04 Roadster runs great and always starts but when it sits a week it takes fuel
Too long to get to carb, I don't remember if my other 3 1200Rs did that

 

I got 3 responses on xl forum and nothing here

 

All I can say is what I said on xl, I believe the fuel evaporates and you have a vacuum petcock. It takes a bit to refill the bowl if it sat for a while. Mine does the same thing, especially if it's sat for a month.
