Thank you for your help briano (& everyone else of course). Problem Solved. I looked at an original head on ebay & the plug hole is flush. Mine is raised up from the head, which would indicate that it has in fact been repaired (crappily) with some sort of sleeve at some point & makes the plug sit too high to thread in.

Hello Kormos_93
Hello I actually did all the testing on these when I ran the ATV R and D dept for Kawi so I’m kind of fond of them.
Your photo is blurry so here’s what I suggest, I have done many of these. To determine if it is an insert do the following.
1. Take a magnet and see if it sticks. All inserts are steel and your head is aluminum. A magnet will only stick to steel.
2. If it does not stick remove head and install timesert, hole looks is too worn for helicoil. If it sticks proceed to next step if you want to repair without removing head..
3. Buy spiral tip screw extractor of proper size. They are available at industrial hardware supply stores maybe home depot tool section.
4. Simply screw extractor into hole and while applying slight downward pressure slowly turn counter clockwise. If extractor spins freely in hole then you must remove head to properly repair.
5. If insert removes then take small thin rubber hose as large as will fit through hole, tape it to a vacuum then vacuum any metal debris out that might have gotten in from removing it.
6. Get right size timesert and installation tool and install.
Scroll down to screw extractor to see what they look like.

Hope this info helps.
Hello
I forgot to mention "you can replace it with a timesert providing the timesert threads match the existing ones once the existing insert is removed if there is one". If they don't match you may be able to get a "thick wall" timesert or just reweld and timesert or helicoil it. Either one will require head removal.
