M or A or B models. That's the year designation.
J = 1972, then K,L,M,A,B.
But what model of bike are you on about as all different ones of say, 1974 were L whether they were 750, 550, 380, 250 etc.
Think of how stupid the average person is, then realise that half of them are more stupid than that.

Have a read at the GT750 part on here, as I guess you're thinking of that model.

On a GT750 the M/A/B barrels have considerably different porting compared with the earlier bikes, aimed at boosting peak power
1976 GT380 - wounded by me, and sold on
2006 SV650S - killed by a patch of diesel and a kerb in Feb 2019
2017 SV650 AL7 - naked and unashamed

You raise an interesting question there. What were the early and late 500 port dimensions?
