3.4 is with the filter change. It is always best to double check oil level with the window. After window says it is full you can pull the dipstick and mark the stick.
When I installed my dipstick I had everything in place and only put 2.5 quarts in. I slowly added a few ounces until the low level mark was met. Then I took out the dipstick a couple times and marked the stick by squeezing it with wire cutters so a strong impression is permanent. Then I filled the bike and marked the upper level.
:waving:Per the 1980-1983 Honda GoldWing Service Manual and my '83 Owners Manual it says to "fill the crankcase with approximately 3.2 liters (3.4 U.S. quarts) of the recommended grade oil. This is the oil capacity with a filter change. Notice the key word is "approximately".
Thanks for the info. I installed the JC Whitney dipstick kit, changed out the filter, and put 3 qts + 12 oz. (.4 quarts) of Rotella T synthetic, marked the dipstick with a hacksaw. No leaks, engine seems to like the Rotella synthetic.
I always just put 4 quarts in whenever I do an oil change on my gl 1100 and never had any problem. Been doing it for 3 years now. If something bad was going to happen from overfilling it, It shoud have happened by now I think...
