Well to make matters worse,as my bike is a very early one, although the studs are 8mm, the nuts could be either 12 or 13mm spanner wise. They're not in a good way so have got a set of hammer on nut extractors from Screwfix. Yes, definately remove the rad as hammers and motorbikes are not a good combination. Got some decorating to get finished, then this task will have my undivided attention. The photos would be helpful if it's not a problem. Thanks :thumbup . What make of stud extractor did you use?
