The Evo has ABS, but I don't know if it's a similar system to the 821. You can get bleed kits (usually for cars admittedly but don't see why they wouldn't work) that use tyre pressure to push the new brake fluid through & remove the bubbles.

The kits come with various caps for reservoirs but I don't know if one of them is compatible with bikes.
