You can use a dremel with a small carbide bit/rotary file and start carefully grinding away at it. Take your time, so as to not mess the hole up anymore. Now this statement doesn't apply to 100% of broken easy outs, but most cases I have seen of them breaking is due to the hole being drilled off center and getting into the base material, or using too small of an easy out on a very corroded or rusty bolt, like an exhaust stud or bolt. Good luck.

Great advice! I can speak from my own experience as a biker who likes to save $$ and my experience in a previous life as a machinist. Any tool that is supposed to remove a broken bolt or stud is extremely hard and can not be drilled out with a regular drill bit. Break it off in a hole you have drilled using any hand drill is more trouble than you want. The most important thing and probably the only real chance of getting it out is drilling a hole exactly in the center of the hole with the broken bolt or stud. A milling machine so you have a ridged set up the the ability to get it centered properly and a carbide end mill is the way to go. Yes it will cost you some $ to get it done correctly but most of the time it is still a lot cheaper than a new head, primary or whatever you have the problem with. It sucks to shell out the $$ for a professional but still a lot cheaper most of the time than a new one. Also gives you some time to decompress with a cold beer and check out other things on your sled. Like I said the professionals at the machine shop will have a solution most of the time and save you some $$. Most of us can't ride right now anyway.

Huh?
You're bolting the outer primary cover back on, and broke off three of the mounting screws?
One? Chit happens.
Two? The universe is sending you a message.
Three? You're not listening.
Maybe I've misunderstood what you're saying here, and if I have, my bad.
But honestly, if you broke off three of those, you're doing something majorly wrong.
Where's this sit now? I'm reading that the outer primary us off, and you've got three broken off screws in the inner primary. Is that right?

Time to call a machinist. And buy a torque wrench.

Just my two cents, from a past machinist point of view this. Removal of the inner primary housing at this stage is a given. As recommended if a shop equipped and able to remove broken items could be your cheapest option. Get a quote from them first. It’ll likely be by the hour type of job. Compare that to just picking up a replacement inner housing.

Yes, this option unless there is enough of the broken bolt available to weld a nut to. If you can have someone weld a nut to the remains it will typically spin right out do to the heat of welding expanding the bolt. As it cools it retracts away from the threads thus freeing it up.
