Can anybody help ????

I am new to building scale bikes, and new to bikes full stop. I am in the middle of building Tamiya's Kenny Roberts 1980 YZR 500 and was wondering if anybody can help me. I was trying to work out what the cable or hose is coming off the top off the carbies and where they are plumbed to. I have photos from a copy of RACER Vol.2 (good pics) but doesn't answer my question. Can anybody help please.:runaround:

Ohh..... does anybody have a copy of Pitwalk Collection#3 - YZR500 Archive 78'88' (thats if they are willing to part with it for a price$$$)
