This may be some help to you.

I have repaired a few Spark Plug threads using a similar kit as in the picture, no drilling required as the tap has the original thread size then steps up to the coil size to help guide the tap square in the old plug hole.

Correct just google [ time-sert thread repair kit ]  and it will bring up options. I thought I posted a picture of the kit but obviously I didn't.

The steel inserts should be available as a kit that will have the proper reamer instead of a drill bit.  It will also have the correct tap and an install tool.  I have done many Northstar engine blocks with this method.

I use Time-Serts, a solid thread insert,    I put grease on the thread cutter to collect the majority of the aluminum as it c8ts the oversized hole, never had a return do to the insert coming back out.
The option with the head removed is similar but more like a rivet style that is pressed into the head.

Cheers  Joel,
What size drill bit do you use before you use the thread tap?

 Anyone  know what can be done about a fix to this dilemma.

The plug felt tight so i  gave it some WD40 took my time removing it.  I had put copper anti seize on the plug when i installed it like i do each time i change the plugs. Don't know why this time it ripped the threads.

Anyway,  can this be fixed.  Im starting to pull the head now.

Had to dig up an oldy moldy to get my switch out. Endless base of knowledge here. Thank you.

Just bought the 2023 CVO road glide and got pro street tuner and vance and hines big radius as part of the deal. I now want to add the extreme air cleaner. Will I need to retune the bike and if so, will I have to start over on the tuning process.
Thank you for any help.

That sounds like the Harley tuner.  It only has a couple of maps.  Your not so much as tuning it, but more like down loading a map to fit the things you have added.  High flow air cleaner and high flow exhaust.  It can't handle any other changes.

I have the Tab Bam stick mufflers and the Extreme heavy breather on my 23.5 CVO Road Glide.  I do not have a tuner.

Any good auto paint supplier should be able to match it and can provide it in a rattle can.

Ditto on above.... the paint supplier will have a device/camera that can be put on the painted surface you want paint for, and it will provide them with the formula to mix up matching paint. I've had it done before. purchased the paint, then had a painter apply it with great/matching results.
