Thanks. That's the info I need.Your pix does not appear to be both 6 start drive gears RH is 3 start LH is 6 start
Oiling a 750 or 828 is identical.
While not 100% cosmetically identical, all pumps originating from large diameter crank engines 66+ will interchange.
1960+ 650 and 750 have a smaller inlet and used usually on 3 start gears but would still work OK for a street motor as a 6 start
500-600 1.5" cranks have narrow gears. I think they are not made any more so wide gear is now used as 3 start only.
More nitpicky differences ...
Maybe 3 vs 6 start was just a bad photo. See additional photo above.
