78" EF Extra 300
WHere the cowl meets F1 former is 9 3/4. I measured about about half way from the very back of the cowl thinking that is approximately where the cylinder head for the twin would be located and it's just a bit over 9 inches where the cylinder head would be when the cowl is mounted
Hope this helps
