No no no.

If you just plugged the wires together, it isn't going to start. There is a diode in the ignition that ya need. Without it, the fuel pump won't prime. It is a security thing.

Get a stock ignition, and you will be good to go.

Gauranteed.

But the diode might be bad. If ya cant hear the fuel pump prime, I would bet you have a bad diode. Mine went bad, and the bike had about 10k on it, and it did what you are describing.

And from what I see, it is quite common.
