But obviously a mix-up with parts labels, the part number is correct for the GT.
But the seller should have known anyway, I think they have good knowledge but sometimes things can go a bit fast. Perhaps an unexperienced employee is doing the listings.

Probably the 80s Kawasaki gt550 inline 4-4stroker
