Split pin out and bolts removed, the centre stand spindle will not move. 2 days of penetrating oil made no difference, nor heat from my paint stripper. Any suggestions?

Is it a tube or solid steel?
The tube type like my 400 are a nightmare.

This was a common problem with the C90’s and probably other models too, although with these clamped at both ends it’s surprising. The answer with the C90’s was to take a thin cutting disc and cut between frame and stand at both ends, sacrificing the pin, then once off either getting in a press to remove pin or in extreme cases splitting top tube of stand to open up with cutting disc then welding back up.

Are you working with a bare frame - l hope so?
With my hollow tube type it involved cutting through the wall of the tube by threading a saw blade throught the tube. I did two slots roughly opposite in the hope the tube would fall out - no such luck.
Even then I had to resort to using an electric drill with a hammer only option to shock the inside of the tube with a chisel . The impact eventually gave some movement that enabled the penetrating oil to do its work. It took several hours over a couple of days to finally get it out. My replacement was a solid pin type on the 400.
My 500 stand pin was in good condition & came out without difficulty.

Mines came out ok using the hacksaw blade trick that Ted mentioned.
When off I drilled the stand and threaded a hole for a grease nipple.
Good luck

I was fortunate indeed ... my centre stand pin came out and was actually in good enough condition to be re-used!

Thanks guys.
Yes, a bare frame. I think it's like the CB400, a spindle goes through both sides of the frame and a tube in the centre stand. It's seized inside the centre stand tube. This is the last thing to remove.
Looks like the only way to remove it, is destroy it :)
I took the frame to the powder coaters this evening. They will try heat to get the stand off, by baking it 1st. If no joy, at least it will remove the grease and penetrating oil, they are happy to powder coat the frame with the stand in-situ. I'll do that, as money is tight, after what I've spent on the bike so far.
But this bike constantly has a sting in its tail! With everything off the bike, the frame was on a lift (under the two bottom frame tubes at the front) and the centre stand. I had a moment of cold dread when I noticed the lower frame tubes are out of line with the centre stand. After measurements, I'm happy the frame is straight. The centre stand isn’t! So, I would like to replace it, but I'm on a budget, already blown on the engine! So I'll live with it for now. But, thanks for the replies.
