"The steering connector and and spindle/yoke will all need to be heated to get the bolts out of them. Then there is the kingpin."
Joe,
Decades ago when I had a motorcycle crankshaft that couldn't be pressed apart even with a 50 ton press an old engine shop owner taught me a very useful trick to solve the problem. This has to be done skillfully to avoid damage to adjacent parts but piercing a hole along the axis of the stuck bolts and kingpins with a flame cutting torch somehow loosens them and allows them to be easily removed.
I was skeptical when that was first was suggested to me but I'm a believer now because it works amazingly well.
The motorcycle was a 1974 Bultaco and the problem was very common only in that one year of Bultaco production. Here's a photo of me in a Southern California AMA District 37 desert race on that Bultaco "back in the day".
