Shouldn't be a problem reusing the gasket.
MAY I HAVE AN OPINION HERE?
I ADD 32OZ. THEN LOOK TO SEE IF THE LEVEL is WHERE IT IS supposed TO BE..... I ALWAYS LIKE THE OIL LEVEL TO BE right to the "SWEET SPOT" on the clutch basket BOTTOM just like HD says...... A few oz. either way should not make a difference UNLESS it is OVER the bottom ring of clutch,,,, THAT is when the problem of TOO MUCH and oil DRAG comes in play.. LIKE MOST agreed on here,,, IT is OKAY with 32oz. in the chain case.(.)
I have a PTcruiser (wifes 01)...... I ALSO USE REDLINE 5W50 in it(plug for red)........
IT NEVER HAS SHOWN FULL on the DIP STICK... always has been a SHORT quart low......WHEN drained (all oil at the right spot and angled correctly to drain fully) it drains out and WHEN new filter and oil is added (correct amount) then started and ran, IT WILL BE 3/4 to 1qt low on the DIP STICK......
IF i leave it with the correct amount in it FACTORY SPECKS it is fine BUT IF I add OIL to the DIP STICK FULL LINE , it goes THRU that quart of X-TRA oil in a week or so... meaning TOO MUCH so leaving it a quart low on the DIP is where it NEEDS to be...
HARLEY,,, TOO FULL IS NOT A GOOD THING... IT HAS NO PLACE TO GO to correct it's self,,, unless it is FULL enough to BLOW a seal and LEAK OUT while going down the road... the hd cases do VARY a little and a FEW OZ. OF OIL either way doesn't make a BIG ENOUGH difference """UNLESS""" OVER THE CLUTCH RING... THAT being the "sweet spot" MAX. oil level.... AND is just that,,, THE MAXIMUM LEVEL oil should be.... OVER and PROBLEMS can show-up!
JUST FUEL for the FIRE!

I always make sure the gasket is DRY of oil.... Synthetic some times finds its way out byy a syphon affect if not.
