I suppose the only place is a local bike shop....wonder what that might cost?

approx $80/hr. My advice seek a used engine as the cost of repairs will quickly exceed the value of the bike.

Wow.......... over here it's the equivalent of $27.70 per hour.

$90 to $100 here at dealers.

Shavings in the cylinder doesn't sound good. You might want to tear it down just to see how bad it really is. More than likely some material has found it's way between the piston and cylinder wall with scoring and some gouging as a result. A new piston, rings and luckily just honing might be cost effective if you can find some one in a smaller shop to do the job. Worst case scenario is a used engine. A complete rebuild is apparently not cost effective to my knowledge and I have never heard of Suzuki selling new engines.

Locally our shops get $65 an hour at $40 hours to take it down and put it back together. $2600...I have seen some pretty nice bikes in local shops for that kind of money, which I don't have.

40 hours on a GZ would be entirely unrealistic in my opinion. If you can pull off the head yourself for a peek a boo it will help you decide. A used engine may be most cost effective. Haven't tried it but maybe there is a chance to sneek a peek into the spark plug hole. Any visible damage might help decide.

If you or your mechanic can get access to a fiberoptic 'scope, you can get a good look into the cylinder and see if there's any damage in there.
I would guess a compression check wouldn't tell you much, if anything.

Results, Monday we are pulling the head off the bike. Having an insert put into the plug hole by a machine shop. I don't expect to hear air pushed out of the hole anymore. The origin of the problem is that the plug had been in since 2000 and when pulled out had aluminum threads in the plug. Bonded together as one. So I the novice re-tapped the hole but it was not going to be the same. The PSI of the engine was just too strong for the plug hold. I want it to be done right so I'm having it done in the shop at $80-100. If I were to have them take the head off and put it back on as well I would be looking at $500-600.

Hopefully you'll get lucky and find no damage to the cylinder, rings, piston, and that your problem was loss of compression to a badly fitting spark plug. Then you can get back on the road quickly.
Was it running poorly before you decided to change the plug? What did the old plug look like? Not one of those if it ain't broke don't fix it things I hope, that's what gets people in trouble.
