420AT speed sensor with SRA secondary gears

So finally cranked up the 420AT over the weekend. When I rebuilt the bottom end I put the SRA secondary gears in for a 15 or 18% (don’t remember which) gear reduction.

Naturally, it shifts into first and second find, doesn’t like to go into third, and won’t go into 4th and 5th at all.

Sooo, anyone have any pics of a shaved speed sensor that needs to be done to get this thing working? How do you know when you’ve shaved enough off?
