The manual claims the CB1100 require 4.9 liters of oil. That comes out to 5.177 quarts, which is obviously wrong.
There was another thread asking about this, but I never found the answer to the question, and it was an old thread. So I'm reasking the question.
What is the actual oil capacity of the CB1100?
I prepared my 5.177 quarts of oil. I removed the filter and drained the old oil.
When I went to refill, after putting in the first 4 quarts, the oil glass was completely full, all the way to the top. In other words, it was over full.
I didn't add the remaining 1.177 quarts of oil, but I saved it as I thought that after running the motor for a while, it might suck up the extra oil... It did not.
A week after the oil change and now I have oil seeping from around the fill cap.
Then I remembered. The same thing happened last year after I had the oil changed at the Honda dealership. Even the dealership doesn't know how much oil this thing takes!
At the time I thought I had a faulty fill cap gasket, so I ordered a new one, removed some of the excess oil with a large gauge straw, and that seemed to fix the problem.
A year later and with a fresh oil change, now the gasket is leaking again.
I'm 99% certain that the fill capacity of 4.9 liters is a typo. Even 3.9 liters would be 4.12 quarts, and my bike is over full with 4 quarts.
My best guess is that they meant to write 3.9 quarts, but accidentally typed 4.9 instead of 3.9, and then compounded the problem by writing liters instead of quarts.
I'm going to try and remove about 0.1 quarts using a Boba/Slurpee straw, and see if I can line it up in the sight glass.
I'll post back later after I get the sight glass lined up.
