snapped bolt on ignition coil

The bottom part of the bolt should come out easily once the top is broken off, get a bolt extractor kit if you can't get it out by hand or with a small drill bit in reverse. Looks like you have a little nub sticking up, try to get a pair of piers on it to spin it out. If not then extract it. Then just buy a new bolt - 6mm x 1mm , not sure of the length, but you can measure the two pieces.
I doubt the threads are damaged so you should find the threads to be okay if you can extract the old bolt.

What those guys said. Be sure to cover your spark plug hole before you start working. I also drill a hole into the corner of the bolt and use a punch to turn it. Good luck.

I agree with eastcoastbumps: that picture looks like you could cut a slot in the stub that's sticking up and use a flat-blade screwdriver. A Dremel with small cutoff wheel is the tool of choice; a hacksaw might work in a pinch.
A left-hand drill bit and a reversible drill is another possibility. The bolt should spin out as soon as the drill bit starts to bite into it. You shouldn't need an extractor, but that's a possibility if the other courses of action fail.

in order to provide an ending to this thread the OP has repaired his valvecover.

If its really stuck take the cover to someone with a welder and weld a dag off the top of the broken bolt. You can then grab this with side cutters and remove the stub.
Take it easy when reinstalling as you could start a perpetual loop if you snap another one.

Just look at the replacement bolt size for the OEM bolt on majestic. the bolt extractor kits will tell you what sizes are in them

you have enough to grip with vise grips or small chisel and hammer. worse case have someone weld a nut but use a welders blanket to cover everything the sparks will leave burn marks. pls don't drill this you will f up the cover and not so tight next time lol.
