Today I change the oil on my 2010 FXDC and had a little problem. The book said 28.7 oz and when I went to the dealer yesterday and I asked of 4 pints the looked at me funny and said it only holds 11-14oz per fork. Well when I pumped out the oil and found that I had pumped out 26oz per side I now did not have enough oil for the job. I also had lost count of the amount of oil I had pumped out. Now the bike is on the stand forks still in and at an angle. The oil level given in the manual is 3.74" straight up in a bench stand. So in order for me to get the right level I took a glass of water, filled it to 3.74" below the top to the glass matched it up against the fork for the right anlge and got the right oil level for the fork on the bike. 3 8/32's" on the high side of the oil level or back of fork. Lessoned learned never assume the parts guy is right. I even asked 2 people and looked at the manual together. They said the 28.7oz is a total.
