Default Front end wobble question

The bike is a '94 FXSTC

I found that in hard left hand corners I would get a bad wobble. All right hand turns are like riding on a rail. The only time the wobble shows up is in hard left hand turns.
First thing I did was check wheel alignment and it turned out the rear wheel was 3 flats out of adjustment so I fixed that and the wobble got a lot better but still a little bit there.

Wheel bearings are new.
Checked the swing arm and pinch bolts.
There is an equal amount of fluid in both forks.

I'm down to thinking that the left fork spring is a bit weak.

Does that sound right to y'all or am I barking up the wrong tree?

The two forks are bolted together. A bad spring on one side would not be any different, left to right. Check the steering neck bearing.

Sounds like you've checked the usual suspects - bearings, etc... You may have a belt separating on one of your tires. Hard to check without cutting the tire open, but try putting bike on a stand and while rotating each wheel, see if you can detect and out of round condition or bump.

Best I can tell without taking them apart the neck bearings are fine.

I was messing with those about a year ago just as a maintenance thing.

With that skinny front tire I check pressure every time before I ride it.
Brand was Dunlop American Elite which has always been very grippy before.

What gets me is that it only happens when turning to the left.
