I bought a 1/2" drive impact driver from Halfords (I couldn't wait ) and an impact stud remover set from Amazon here; http://www.amazon.co.uk/gp/product/B001D...00_s00_i00

Most of the larger 1/2" drive extractors range from 6mm up and since the studs are 6mm I wasn't confident that it could get a significant grip. This is why I bought the set which included the 2mm-8mm extractor which worked pretty well. On one of them I almost couldn't get the extractor to let go of the stud once I'd removed it  :lol

After several wacks from a hammer, they all (bar one) began to shift and allowed me to use a socket wrench to remove them without sheering them off any further.

For those who may be interested, the machine shop (Star Engineers in Broomfield) were very helpful and it ended up costing me £40. Since this was for two studs (drilled out, re-tapped and heli-coiled) I didn't think the price was too bad

As much as this worked really well for me (they were all very very badly corroded) I did remove the engine to get decent access. I reckon I could have gotten all 8 out without too much issue if I'd been a little more patient with them.

Taking the engine out is a huge deal but it does take a while - took me a day to remove and a day to replace and this was in winter (early Feb 2013) where the days were short and damn cold. I also didn't have a garage or anything so this was done outside but it worked and saved me a hell of a lot of money. If you only have one to remove, then leaving the engine in situ to attempt a repair is a better idea but access is a bit harder and you need to be more careful with the balance of the bike and how much force you are putting in which direction... I could whack the hell out of my impact driver as the engine was out and resting on gravel
