It’s relatively straightforward to fix with the head off, not so easy with the head on. Have you a pic?

easy enough fix for a good welder
Re: Rev counter securing post snapped off
Maybe worth trying supafix?

I've used it a couple of times and it worked a treat, been used in a couple of fixes in CMM magazine too.

Lots of liquid metals out there, I have used Locktite before with some success.
Theres looks to be a bit if the hole in the head still left? is it threaded? have you tried a longer bolt, or maybe a combination of both liquid metal and a longer bolt to catch the last couple of threads.
Best way is to take it of and get it welded tho

Don't do the liquid metal and longer bolt at same time, stick it first wait for it to dry the clean the threads and fit the longer bolt, otherwise it'll be there for good and you'll never get it out without breaking it off again

Re: Rev counter securing post snapped off
If you glue it you will be doing it again at some time, as it heats up and is also flexed by the cable during handlebar movement, only one way to do this job and that is correctly.
Re: Rev counter securing post snapped off
looks like reason it broke is the use of a chisel or similar to try to remove the screw ( see witness mark in the side of the screw head ) - anyway that aside - suggest remove cam cover to evaluate the thickness of the casting where the screw was and how much material is left - if you have around 6 mm or more - remove the stump that broke off and find a drill that slides in to it ( tapping drill size ) - using the stump and metal bracket as a guide carefully drill deeper into the head casting about 5 mm - tap the hole with a suitable tap ( taper first then Plug ) drill out teh stump to a clearance hole size 0 and use this as a spacer with a longer retaining screw - if casting insufficiently thick will have to be welded - a good tig welder should do this easy enough
whoosh im gone
