Wheel flop, fork length, and head angle

Makes sense, if the energy state of the bike is lower with the wheel
turned then it will turn. Unfortunatey the only way I can see to
change the offset is to change to a different fork and I like the one
I have in other respects.

If you can find or make (or have made for you) a fork crown/steerer
assembly that accepts you current stanchions but has some offset or
rake built into it, then you might be in business.

A lot of 20" suspension forks use the old Rock Shox Mag 21-type
standard of 1" leg diameter on 107mm centers. If yours is like that,
you are in luck-- Mag 21 crowns are raked to provide offset for
sliders that have no offset at the dropout. RST crowns have a touch
of offset but no rake. By switching to a crown from an old Mag 21 or
one of its clones, you will combine offset at the dropout with rake at
the crown for more total offset than would otherwise be possible.

Thats great, I may find a trashed Mag 21 at Recycled Cycles to part out. I know
the leg diameter is right but I have to check the spacing. The trick will be to
get a crown that will take a 1" steerer.

I would like to improve the steering stability.

I encourage you to pursue the measure of adding fork offset to
normalize your bike's steering characteristics, but there is one
relevant fact which nobody has yet brought up:

you've got it backwards. Increased trail adds stability. Decreasing
offset increases trail. Increasing offset would decrease trail and
make the stability issue worse.

Normally, but the bike in question has 2.5" of trail already and its
main handling issue is wheel flop. More trail would only make it
worse.
