You need to start over. Empty your gas out and replace your spark plug.
When breaking in a new motor you should never use full synthetic. We break all our bikes in with castor bean oil and gas in a 35:1 oil:fuel ratio. In 3.5 years we've never had a problem with our break ins. Nothing over 91 octane is really necessary but don't go under that either. After one or two tanks (personal preference) then we bump up to a 50:1 synthetic blend. Once you're through with the breakin gas you'll notice a difference in power, for the better.
Ratio Rite is your friend. I hope your bike didn't partially seize.
