If you have a scissor jack put it between engine and exhaust (use wood or rags as protection) and apply pressure, then leave over night whilst spraying header collar with wd40 (other products available) but be patient.

Had to do it on my gs750 when we originally stripped it down.

the jack sounds like an idea im using a ratchet strap around pipe and a fence post i will try a jack
cheers dave

its more likely to come out if you twist it rather than pulling or jacking it out. beware, too much force might damage the ally of the head before it damages the steel of the exhaust.
