82 xc/cr frames

afaik ...the84 LC's were the first bikes to go to 28.5 degrees rake over the 30 degrees of the earlier (desert orientated) bikes

Another way to do this would be to use a set of Aftermarket Triple Clamps to change the Steering Head angle. Except I doubt the Aftermarket is going to jump in thinking they are going to have many sales. However since putting modern forks is somewhat popular for our bikes that would also mean that a set of Triples intended for a more modern bike could also be used. I have a 2000 KTM 250 that has a set of Billet Triples but they are not marked as to what the Rake change is if any at all. But I'm sure they would bolt right on, as long as You were using the correct diameter Fork Tubes. And what the heck why not machine donuts to make them work with our Forks. Maybe welding wasn't so bad after all.

Triple clamps with 5mm less offset would make for sharper steering. Then you have to do the research to find them

I don't see a difference in my sets from 81-84. It's 1985 and newer... The clamps I have from the single shock'ers have more offset.

More triple clamp offset reduces trail.

It's very simple.

It has been proven on a XT500 French trials conversion that using straight leg forks in offset fork triples(offset changed from 60mm to 30mm) resulted in trials caliber handling that was test ridden by Mick Andrews and met his approval. No frame cuts utilized.

I was wrong about the effect direction of trail but the fact remains that less triple offset will sharpen the steering capability.
