it would hit high RPMs and then settle back down, but was irratic and loud.. I shot it with WD-40 and it idles perfect, it seemed to be an air leak around the pipes going from the far left carbereutor
What pipes are you speaking of? The intake manifolds? What did you spray with WD-40?
Can you post a picture or diagram from buykawasaki.com?
About the noise, have you had the exhaust pipes off the bike? Maybe one pipe isn't sealed right at the head, or an exhaust gasket at the junctions is blown.
Look at Timeserts instead of Helicoil. Search the forum about it, some guys think they are better then a Helicoil. Might be cheaper, I don't know.

However if its only the top 3 threads then you may be able to restore it as suggested with a tap. However these tools are quite expensive for a one off job so maybe get a shop to do it or lend hire you the tap.
I have used old spark plugs to clean up spark plug threads. This involves breaking out the centre electrode and cutting slots down the threaded portion with a hacksaw. The problem will be starting it as unlike the proper tap it will not be tapered, so real care will be required not to make the cross threading worse.

What else could cause the bike to be louder? It just sounds deeper, I also had put some seafoam through it beforehand, could that cause it?
Thanks,

I recently fixed a couple of stripped plugs with Timeserts, but I was lucky that had a friend with the kit already. He let me borrow it, and I went ahead and ordered six more Timeserts from fleabay.
Orielly's auto parts has a plug hole repair kit that looked like it would work pretty good, and it wasn't as expensive as a Timesert kit. The one at Orielly's had a couple inserts, a tap, and a swaging tool that swelled the inserts pyramid shaped serrations into the head after you tap the hole and thread the insert in.
I'd recommend using some red Loktite on the insert.
Just don't do what the previous owner did to my bike and JBWeld the plugs in, or the next owner of your bike will make a Voodoo doll of you and stab it with pins and put cigarette butts out in its eyes.
