Frame number ID 1990 or 1989

[Digs]

Just looking at my logbook on my 7/11 before submitting my v62 form, my original engine size is 748cc which says to me it's a 1989. Wondering if anyone can help with the frame number ID: GR7AA 102205 

It's not going to make a huge difference to me, but I'd like to know.
