What Size Cables For Yam 250?

[Salty Dog]

For some reason the main cables for my 91 250 Yamahas were put inside the engine bracket. There are lugs there where 2 or 3 cable meet up. The large positives are corroded and I wan't to put new crimp ends on. These are the factory ones that come from the engine. If anyone knows what size these cables are it would save me some time. Size 2 or 4? What about the negative?

thanks
