NEED HELP IDENTIFYING KX80 YEAR!! Please help

[97cr125#14]

Hi my cousin has a Kawaski KX80 and he was told it was 1986. But I'm not 100% sure. I can't check the VIN number because its been grinded down. But it need to know the year of it so I can order parts for it. Can anyone give me any info on how to determine the year just by looking at it?

Thanks.
