What is your bike doing if you are not trying to jump it. Does it turn over at all if you are not jumping it? Could be bad gas for sitting over a year. Charge your battery to full before you try again also check the bowl drains on both side of the carb and see if you have gas in there. I had a vaccum tube blockage once and caused the fuel to not get to the carbs. Just thinking of little things, I'm sure someone smarter than me will chime in any minute.
Don't worry!!, It's just a bump in the road.
