Ok I'm at my local Dunkin donuts and a friend stops by And ask me how much fluid to put in a 2005 deluxe primary. I tell him 28 onces he said the book said 32 I said that's for a 96 ci or later model any one know what the book calls for on the 05 twin cam 88

 

My opinion is the correct amount or less is better then too much. With it level and upright fill it to the oil is just at the outer edge of the clutch outer drive fingers. Do not know about yours but the owners manual and service manual sucks at showing this. Actual 15-20 oz would work since the chain dips way down and wips the oil up but do it to a level, not oz.

 

26 oz in the manual. You are right, the 07 and up's are 32 oz's.
