Could be that the starter sprag clutch was jammed so trying to turn the starter motor (from mechanical means) all the time.
Could try removing the starter motor and see what you get.
As Graham says, it's not adding up so something we're missing somewhere.
PJM47:
It's not making sense to me either. The basket rotates if the engine is turned using the alternator bolt so that must be free. The kickstart rotates if the basket is not fitted so that must be free. All gears select ok and the rear wheel turns in any gear without the basket fitted. But with the basket fitted the kickstart will not move and nor will the rear wheel.
I'll have a look a the starter next. Is it easy enough to remove?
Trigger:
The part that i have indicated Blue pointer is the basket mount and will move when you turn the crank. The part indicated Red pointer is to the gear cogs and should only move when in gear.

If the alternator housing is off, all you need to do is remove the small cog that connects the flywheel to the starter motor so, no need to remove the starter ;)
Primus:
Sorry, I don't have any technical input to offer but I am enjoying this thread (in a perverse sort of way!). I really hope there is a successful conclusion to PJM47's issue. It gives me the confidence should I encounter a serious issue that I can't resolve, that there is help out there. I'll continue to watch from the sidelines.
