How far have you got so far? Some pictures would be a great help, but remember to downsize them using Shrinkpic (instructions at top of menu).

The BSA E and G engines are 420cc, looking at the diagram in the parts list it looks as if pulley is held on by large nut on end of crankshaft. Instruction manual does not sat anything about removal.

Just a thought, could it be left hand thread??

Thanks guys, no large nut , obviously threaded end thinking left hand thread is probably it. Thanks hortiman. Will give it a try and see.

Anyone know the best place to get the magnito repaired. Never done one and don’t want to trash it.
