Good luck.
I will leave it into the garage

Can we get uprated studs from Ducati? I presume should of been used from the outset

Are you saying that the broken stud is on the horizontal cylinder ?
If so, that could be seen as a less costly repair job because I'm assuming it can be fixed without taking the engine out of the frame (I'm also assuming that a broken stud in the vertical cylinder would require engine removal to fix).
As I said earlier, the weaker studs are shiny/silver while the stronger ones are black. Of course rust may have obscured which is which by now, but you could probably still tell with close inspection.
If you do have the weaker studs then I guess its your call as to whether you replace those in the vertical cylinder as well (as a preventive measure) or leave those as they are to keep the cost down.

What year is the bike ?

As utopia says, Ducati did produce stronger studs to eliminate this problem and they are identified by their colour. There may also be identifying letters stamped on the ends of the studs. Have a look here for some more information (posts #808 - #811):

Yes its in the horizontal cylinder behind the oil cooler (throttle side), they are all rusted so hard to tell

I will have them all replaced , its a 1997 bike ; 6K on the clock

Have the belts on the 748 to d too and insurance renewal this month ; expensive month ahead!

Monster just got fresh Motor tax, puncture , new tyres, 2nd puncture in new tyre fixed , oil change , new brake pads , new starter solenoid , new uprated power cables ...two spins in ,front head stud decided to go .. disaster , everything I take it out something breaks or I get a puncture lol

Had a look at the service manual last night with all this talk about spark plug gap ; OE is 0.6mm

I ordered some new Iridium plugs, preset to 0.8mm gap ; not too sure if I need to re-gap to 0.9mm/1mm

It appears it is a common issue people have with them , rear plug gets carbon deposits / fouls ; they run rich from factory , not too sure if you do anything to improve combustion

Personally I would be a little wary of fitting Iridium plugs to the old 2v motors particularly one that appears to be fouling them up as those little electrodes can soon become clogged and coupled with a bigger gap for the spark to jump you may find after a short while you’ll experience rough running, whereas the standard plugs with less of a gap are much more tolerant of it.

Bad luck on the broken stud, happened to my 900SS but it was a rear one, but I found out it was possible to replace them without motor out job despite what some 'experts' would have you believe. The front ones are much easier and cheaper to replace but less likely to break. If you can't get the Ducati ones and if ordering from Italy would likely be a logistical nightmare right now, Geoff Baines used to supply his own versions and that is what I fitted to mine. So might be worth checking Baines Racing if his outfit is still up and running?

I've been following this guy's Supersport rebuild and he's just got to the stage of reassembling the barrels and heads using the black studs.

At 18:25, he shows the special tool needed to tighten the head bolts and how to use it (at 90° to the torque wrench). Dimensions are also given if you want to make your own.

Interestingly, at 19:50, he quotes different torque settings for the silver and black studs (42Nm silver, 39Nm black).

By the way, if you watch the video through from the beginning, you'll see just how useful Richard's home-made circlip tool actually is. http://www.ukmonster.co.uk/monster/s...postcount=1070

Turned out a head stud was replaced in the same section , they only replaced 1 Stud and left the other 3 untouched ; strange to go to the bother and not replace the 4

I replaced the speedo drive but mechanic said I need a new Speedo Cable

Just OE or any other alternatives

Stein Dinse are listing one for 12.95 euros which I assume is a pattern one because they have also one for 35.70 euro. Not sure what DHL shipping would be though.
