Have a 64 Allstate with a stuck headset I'm trying to remove as part of the teardown.
Through bolt has been removed (actually missing when I got the scoot) so that's not the issue.
I've restored several of these before but never had one with a stuck headset.
Any suggestions?

I'll be posting progress pictures once the process is underway.

Is there rust corrosion on the fork, which is binding the headset? This happens on the throttle/gear tubes often. Soak it in penetrant, and might need to add heat to break it free

Thanks geeklion, that was.my thinking.
Probably rust down inside the joint.
Wasn't sure how the cast headset would react to heat.
Will update on how it worked.

Heat. HOT heat, applied directly to the steel tubes. Put some copper sheet behind the tube to shield the rest of the headset. Use a MAP torch. The tube has to be cherry red where it passes through the headset to break the rust bond. Donít wimp out.

Wait... headset stuck on the fork? Or throttle and shifting tubes stuck in the headset?

If its the headset stuck on the column/fork get it in a wheel chock. Add penetrant and try to get some left to right wiggle. Add more pentrant, etc etc.

Heat can help but it will roach the paint and you can cook your harness and cables too so proceed with caution there.

My VNB headset came free with the method above. No fire required.

Yeah what exactly is stuck?

If the headset is stuck on the fork, Birdsnetís advice is good. Chock, lube and twist. If that doesnít work, get the cables wires etc. out of the way and bring the heat.

As a general rule always use penetrant first. It will eventually work if there is any movement. But for penetrant to work there must be space for it to, uh, penetrate. To create space, heat is required.

Having dealt with seriously rusted parts, I am here to tell you that the key is to apply heat to the STEEL - in this case the fork - to break the rust bond.

Headset is stuck to the fork column. I'll try the "penetrant and twist" dance first since it seems to be the least drastic and less likely to cause.more problems.

Success!
A little WD40 sitting overnight and a few well placed raps with a deadblow mallet and we have movement.
Onward!

PB Blaster is your friend on jobs like that. Sometimes heat.
