The AE from the factory will engage at 1800 RPM (on the way up from being in idle). The bike should disengage at 1300 RPM (on the way down) from engaged to idle. This is why with slow speed manuering the majority of AE owners will utililize the rear brake in order to keep the bike above 1300 rpm which keeps the clutch engaged while at a crawl.
Update from today:
While doing the advanced TBS today I went ahead and undid the spring release. That only took me 1 12" ziptie, 4 hours of time, and an infinity of patience.
When done I took it for a ride and believe the following to be true:
1) Previous owner also did a spring unwind, as the throttle spring 'hook' was barely resting on the catch before I rewound it
2) When decelerating there is the aforementioned 'pop' and there is no longer the need to push the throttle all the way forward
3) When coming to a complete stop it still requires braking to get it down to the 1300 clutch disengagement, but less than when I had the release done yesterday. I am willing to bet it I wound the spring one more time to the stock setting this would be even less noticeable
So I think ScottyUSN is right on target. When taking off the clutch engagement is at 1800. As I decelerate the disengagement is at 1300. I believe this is what's happening in the scenario that I was referring to initially as '1 Low'. When I am in first and need to make a tight turn, I ride the brake until about 10mph (1300 on the tach), it feels like a 'downshift' but this must simply be the clutch disengaging, then reengaging at higher RPMs to allow slow navigation. So I was always in first gear, simply the clutch was disengaging / reengaging. Sound right?
So a last question to AE owners. If you come to a rolling stop, without braking, does the clutch still disengage and the bike come to a stop on its own? Or does it still require holding the brake to force the disengagement? And was this with the stock throttle setup or with the release done? Thanks.
