How to helicoil?

[Beehive Bedlam]

How to helicoil a fucked spark plug hole? I've a vague idea but I've never done this task before.

Fucked hole.

Do I need a tap wrench for the tap to cut the new threads?

As you can see the cylinder walls are in the way so vice grips/mole grips won't work or can I simply flip the head and go in from the other side?

Did you strip it? If so, HA-HA.

No I didn't strip it there was no evidence of cross threading on the plug either. To my untrained eye the threads look worn out.

I've seen that video. I don't have a tap wrench so have nothing to grip the tap with and the cylinder walls won't allow me to use vice grips.

Can I flip the head to cut the new threads?And flip it back to fit the helicoil?

Also I've a couple of questions regarding the HG whilst I'm at it I know reusing one is like reusing a condom full of spunk but what if I cleaned off that spunk and gave it a squirt with this?

Halfords 1/4 rachet + 10' extension bar with a 10mm socket on the end was my handle.

I've been putting off doing this for the side stand on my track bike (previous owner put 10'ish mm bolts in 28mm bolt holes, in an ali frame, for a side stand...
Only noticed when it was leaning at 40 degree angle one day on the stand. Both holes shagged, Helicoil kit bought, hoping the holes are't to ovaled. Could a heli coil in a heli coil work?

Need to get the rear suspension out to get in there though :-\

I would have gone with a solid collar insert for a spark plug because you screw it onto the plug first then into the hole but fair play, you've done it the harder way so well done.

Well done Fazer - good job there. Helicoils are good but accuracy needed when tapping for them.
