My manual says to fill the primary with 38oz of fluid. Are you guys putting that much in or is 32 enough? I want to use Formula + in it but don't want to buy another quart just to get 6 more ounces.

 

Luckily the gas tank isn't 6.2 gallons..... I have heard both ways i do the 38 and a harley mechanic will do the 32. If this is your last change you will ever do then go with 32...if you are goning to change it again then you will be able to use the "Extra Quart" Think of it as buy 1 for next time.

 

I THINK 38 is for a dry primary (completely empty) and 32 is for a fluid change.

 

I don't have the book in front of me but I thought it said a number like 48 is if it is dry??? I filled it up to the mark and 32 looked a touch low BUT 38 looked the same just a smidge higher???? So IDK for sure I just went to what I read the book saying. A family member works at H-D and he puts in 32 on his???

 

Looking at the Service Manual it says 38 oz. wet and 45 oz. dry. Reading other post sounds like most just use 1qt. Bob

 

These pics was taken after my 1000k service done by the dealer.

I don't put a measured amount in, I just fill to the bottom of the clutch basket.

 

Negative. It is 38 and 45.

Buy 2 quarts, put the partial on your shelf, you'll only need to buy 1 for the next 4 changes.

 

Even so, 1 quart is all it ever takes on my bikes at fluid change time.
