By 2006 all H-D's went to Dot 4. I used to like the Dot 5 silicone stuff only for the fact that it wouldn't damage paint and didn't draw moisture. Under a microscope (i've read) Dot 5 is full of tiny air bubbles. It's just part of it's make up-they never rise to the top. This accounts for the spongy feel when using dot 5. All new H-D's are Dot 4 and have a MUCH more solid feel, than the Dot 5 days. Reservoir level should be 1/4" from the top per the service manual (reservoir level has no effect on feel at the lever what so ever) it would have to be empty or completely full (not allowing for fluid relief port return and the pistons in the caliper would probably stick out)for this to happen. My 2cents-Glenn.
