If you are putting 38 oz. in after draining you are overfilling.The spec is for a completely dry primary something you can not achieve by just draining the fluid.Bet your bike has a heck of a lurch when you start in gear.:s
Steve07,
Sorry, but your wrong. The service manual clearly calls for 38 oz. wet and 45 oz. dry. I just did the service yesterday and I just now rechecked the manual.
My bike does not lurch into gear at all. I keep it well maintained and follow the manual closely.
This is a good example of why everyone should buy the manual and then actually refer to it when performing maintenance. I can't count the times that I have seen people with good intentions give inaccurate advice.
I have an 07 FLHR, maybe earlier years have a differant spec, but I'll go out on a limb and guess that the "07" in your user name indicates you too ride an 07.
