not recommended- this will wear the alloy thread after a while. If you think about it Innocenti had studs everywhere rather than screw in bolts for that very reason.

I assumed that the chaincase cover had been removed ? if the stud is sheared off why will the cover not come off so you can get some stilsons or a stud extractor on the stud and do the job properly without damaging anything .
This is where a simple image in the first place can help explain a thousand wasted words

Great bit of kit , but will it work with chain case still attached
No, you'll need to take the chain case off. Don't spoil the ship for a ha'porth of tar. That's how things get bodged in the first place by people cutting corners. Get the correct tools for the job, they can always be sold on to recoup the outlay. Not sure who sells patience though.

very true C but its easy for me to say now that I don't have any commitments like a family and I don't have to be so careful with money
A pair of stilsons will do the job very well and you should be able to borrow a pair off any friendly neighbourhood plumber or C Heating engineer for free. Stilsons work on exactly the same principle as a stud extractor but have a more direct connection with the stud.
If the Po was anywhere near another member I'm sure they would offer to pop round and extract the stud.
The worst thing you could do is use a Mole wrench which will simply slip and chew the stud to bits leaving no option but to drill and helicoil.

by the time you've posted on here half a dozen times, you could have had the chaincase side off, studs out, new gasket on and case back together.

Cut or file a slot on the top and use a screwdriver?

It's a £8 tool on a £4000 scooter.

on any of these methods of stud extraction i would strongly recommend the use of a blow torch for heat,if studs have been loctited in you will certainly tear the threads and then need helicoils!
if the stud is not damaged just too short i would strongly recommend the long nuts as a spacer which can be wired together and then bolt the endcan bracket onto them,
this age old problem of tailpipe studs stripping i would have thought pipe designers would be using tougher mounting points that will not give any trouble like the bottom damper mount and rear jacking hole and clamping round the engine mount,
