needle & seats for a 2005 rstd

[by-tor]

im looking for a cross reference part number for my needle valves and seat seals for my 05 rstd... mikuni makes carbs for a lot of different bike manufactures in cluding harley. i cant get them through any yamaha srvc cntr, they all tell me they are 5 -7 days out and im leaving for yellow stone tomorrow ( supposed to ), and i live in michigan. my thinking is that another srvc cntr has the parts i need but i dont know what part # to ask for or what bike ( other than mine ) has these carbs. how do i get this fixed by tomorrow so i can leave at 3pm????
