The No.4 slide will work out ok on this. If you are sure 125 main jet is a bit rich, then you will need a BE5. Stick to pilot jets that end in 120 starting with 50/120 and see how it goes.
Good you are just using AFR as a rough guide to see the direction to go in. This is what they are good for.
Would be nice to get this done before the move. If there are scooters in TN you want to be able to keep up
