1 qt but don't overfill and check when hot. I keep mine between hot add and hot full and no blowback.
I do the same and with my 2020 breakout except I run it between hot add and half so I am about 1/3 up the dipstick from add to full and if it gets close to add I add a couple ounces and with my Trask air cleaner I can really see what is going on and do not have blow by issues either. I have a 128 big bore build also and have put 14K miles on the build. if anyone thinks I am running it too low call me crazy. When I ran it half way or 3/4 to full when hot , I was getting a little blow by here and there so
