Thats what happens when spark plugs are over-tightened =) good job on the repair! I used to heli-coil aircraft cylinder heads, and I can say a good helicoil job will withstand anything you throw at it!

Just a follow-up:

According to NKG (the spark plug people), and echo'd by Suzuki, the following spark plug install install advice applies (the stuff at the top I added):
========
The block is made of aluminum, while the threads of the spark plug are made of steel. The potential for damage to the block's threads from mis-threading spark plugs or over-torquing them is extremely high.
Coating the threads of the plugs with a light coating of high-temp anti-seize compound is highly recommended.

Installing Brand New Spark Plugs:
Using a spark plug socket, turn by hand in reverse (counter-clockwise) to line-up the threads, then turn clockwise by hand until snug.
Using a Torque Wrench per the Suzuki factory service manual (torque wrench highly recommended!), set wrench to 8.0 lb-ft (aka 11 N•m, aka 1.1 kg-m, aka 72.0 lb-inches) and torque to spec.
Without a torque wrench, per the Katana owner's manual, once snug to the hand, turn 1/2-turn for brand new spark plugs.

Reinstalling Used Spark Plugs (NOT THE SAME IF NOT USING TORQUE WRENCH!):
Using a spark plug socket, turn by hand in reverse (counter-clockwise) to line-up the threads, then turn clockwise by hand until snug.
Using a Torque Wrench per the Suzuki factory service manual (torque wrench highly recommended!), set wrench to 8.0 lb-ft (aka 11 N•m, aka 1.1 kg-m, aka 72.0 lb-inches) and torque to spec.
Without a torque wrench, per the Katana owner's manual, once snug to the hand, turn 1/8th-turn for used spark plugs.

Thaz, I was going to replace the other three plugs when I got the bike from you on Friday because the tank was already off, but then I decided not to because I keep hearing about the over-tightening issue and I didn't want to screw anything up because it was already running smooth. Maybe one day I can ride(not trailer her ) her back down your way and have you to install the other three plugs for me?

[ThAzKat]

OK, just something I do personally, I pulled those and they look good to me! I also checked gap, you are good to go!
Now that I get to see your bike with all the fairings on it awesome bike catcha!

Thx Thaz! You should feel special now, I don't normally allow guys to see my gurl naked like that. Not only did you see her naked, you felt her up pretty good....

[ThAzKat]

even got in her heart
You are welcome bro!

[Catcha23]

I have done this before and trust all will be good and I back my work cyber. If catcha23 has any issues with this, I will cover it and do him right. As I do all my customers.
Have you been riding Catcha? how is it doing?

Thaz, I took her for a spin up to Hocking Hills/Old Man's Cave yesterday evening for a spin. She did fine on the highway and great in the twisties! I kept her under 72 on the highway. I didn't try to work her too hard. She held up like a champ, thx again.

There were plenty of deer in the middle of the road up there last night around sunset. They would be standing right in the middle of a blind curve to. It was a great evening to ride!

[ThAzKat]

Oh sure, rub it in that you went to hocking hills
The wife and I are going to head that way one saturday!
