Was your 450 running when you jumped the other battery? If not the low battery could draw down the good battery, as indicated by the hot jumper cable. Try jumping from a car battery with the motor running.
With the plug out, turn it over several revolutions with the starter to clear any gas in the cylinder.
When bump starting if the tires don't roll try a higher gear, and just as you engage the clutch, bounce down on the seat with your butt.
