Well, I won't be bidding against you if you see tooling on ebay, as I luckily got a complete set of tooling. I have seen tooling from time to time, and there is a used machinery dealer near me that has a decent selection of these tools. They are usually about $25 each, and I bought a couple of the ones that I was missing there. Thier website is:

It's best to give them a call, and expalin exactly what you are looking for. They may even ship items, but I have never asked before.
I understand what you mean about ideas banging around in your head, I'm the same way.
Good luck with the motorcycle parts business. It seems like there is plenty of oppurtunity, especially if you have a safe product.
