Don't normally need hot air gun for Bultaco unless someone has used sealant on the centre gasket.

gearbox output sprocket and seal spacer

cylinder

shift drum external mechanism

shift drum indexing plunger

all the nuts and screws - one screw is tricky to see

You also need to remove the primary drive and the clutch. Basically everything on the primary side. David forgot to mention that. Don`t lose the small washer on the kickstart gear inside the center cases.
