Spark Plug Threading all messed up

yes and heck if you wanted to have more depth you could maybe epoxy the hex head into a deep socket.

I know my redneck methods make people cringe but I would do that to a 30 dollar tool to get the reaach before shelling out more for the long ones.

KD tools makes long one I think

I don't mind destroying a tool that I have more than one of to make something work. Not really worried about the depth, I don't plan on having this bike past summer so maybe 2 more plug changes are in store.

thanks for the advice!
So first I should just try and re-tap , using one of these-http://www.denlorstools.com/home/dt1/page_15542_273/kd_tools_kd_3379_spark_plug_thread_tool_14mm.html

and if the threads are already to messed up i should use a thread repair kit?
To use a kit like this do you have first drill the spark plug?
How does a kit like this work, it says no-drilling required?

ok, that works exactly like mine did. the expanding/threading tool just threads down into the hole into the old threads as much as possible. then when you are twisting it down in, the remaining threads will pull it down into the hole and it will cut out a larger hole and then thread the new diameter all at once. Just turn it in some until it binds a little, back off, turn in more, back off, it's easy. Put a little grease on it to catch the shavings. Then once your hole is threaded properly to the larger size, check which insert to use and test fit it. Then put some locktite on it and thread it into place. Then use the expanding tool (it goes in the unthreaded end of the insert and you give it a solid smack with a hammer to expand it into place so it locks it's self in) and you're all done. Wait a full 24 hours for the locktite to cure before firing the bike up. Also put a little never seize or antiseize on your plugs prior to putting them in. The copper based is the best for hot places like that if I remember correctly. (it has a copper colored tint to it instead of silver) Then you're all done.

that makes it clearer, thanks!

Yeah, don't worry about it. It's an easy fix and you'll never have to worry about it again.
