Yup. SpeedyCorky helped me out by posting the part# for his Vortex Gas Cap. In summary:
The Vortex CP402 aluminum gas cap fits the NSR50 tank which is actually designed to fit the following Kawasaki's:
ZX650R 2006
ZX6R 00-06
ZX9R 00-03
ZX10R 04-05
ZX11R 97-99
The frame is out getting tabs fabbed up and welded to the subframe but I unfortunately won't be able to get it back until early next week.
After it comes back, the frame goes to powedercoat finally and I can start to finally start to rebuild the bike.
