Engine full of fuel and seized up

PJM47:
OK so hope you are all still interested in this the one folks. Think we are getting to the end. Not sure who is on for winning the sweepstake.

So I removed one rod at a time as suggested thinking at some point it would free up, but got to the last one and guess what, it is still exactly the same, it turns a bit then gets stuck. As everything is loose it now actually lifts the crank out of the case / bearings if I try to turn it more. The primary chain is off at this point and there is nothing left connected just the crank sat in its slot, it won't rotate freely.

It looks like the big gear behind the alternator is right up against the case and maybe getting stuck in places, its very close anyway. So bent crank or maybe just that gear is bent? Should it be so close to the case?

Just try oiling the shells they won't turn bone dry.

Yes they are all fully oiled

Trigger:
The wheel on the flywheel does sit close. It is very hard to bend a 750 crank, are the crank case shells equally worn ?

I'll take bent crank please Eamon. I've bent a Triumph T140 crank, and they are positively agricultural in comparison. Amazing what hydraulic lock can do, its the irresistible force meeting the immovable object, but something has to give.
