Score one for the home team! I'm from east central oklahoma.
Pistons, stock head, and obviously the crank is all trash. Mic the cylinders and see what you come up with. Depending on what your budget, you can get as wild and crazy as you want with these bikes.
If your wanting to just keep it stock and get it running again it won't hurt your wallet as bad. You can find a lot of great deals in the for-sale section on here.
You can also call and ask questions to any of our site sponsors. They would be glad to help you. I would personally recommend FAST Racing or Redline Racing.
