If my memory serves, 1 qt is just barely enough. It depends on where you set your oil level.
Since the front of my bike is heavier than a normal TA and I hate fork bottoming, I set mine up with a bit higher oil level than normal.
Don't remember the air gap measurement but I think 115 mm. Standard is, I believe, 125 mm. All measurements suspect due to corrupted hard drive in my head.
