Busted Fazer - what are my options?

[Farjo]

We get 3 or 4 breaks through the day so it's not so bad, and it means we work fewer days for the same number of hours.

"The more you can do to get it ready to pull out the better ie removing as much as possible" - as shown in the pics the downpipes are still on - shall I have a go with the other studs? How much time and effort is it to fix each snapped stud i.e. do I have to be super carefull to get the last of the nuts off?

I assume I'll need more studs - if so I'll get stainless ones off of ebay.
