That's the later "low dome" piston with lower 9:1 or 9.3:1 compression used in early monsters and the early 90s SS.
Same 88mm x 61.5mm bore and stroke but not what I need.
750F1, 750 PASO and 750Sport - three models covered 1986-1990 all had the 8mm dome
10:1 compression piston ( 093528 cast on the inside) - thats why Paso's go so well.
Yes, I know there's a diff but didn't want to judge. Ferracci makes a set of pistons for the pantah 750 in 11:1 and I can put you in touch with Bruce Meyer (BCM past owner) and he can make them for you by turingin down a set of 12:1 Wiseco pistons. He has them in stock.
