Bike sat for 8+ months, wont run for more then a few seconds now
SO, I bought a Kawasaki Ninja 250 back in 2010. It was my first motorcycle, and I have pretty much zero mechanical expertise.
It ran fine for the first 2 years we had it, but, I'm military, and had to move to lovely Minot, North Dakota. If any of you know how military moves work, they want you to drain the fuel from the bike before they'll move it, for safety reasons I guess.
I drained it on my own by emptying the fuel from the tank ( i think, the drain i used was on the left side, right next to where you switch it from ON to PRIME ).
So, when we finally get moved in and our stuff arrives, so does winter. So we don't change the oil or put fuel in it or anything like that because, its fucking hella cold outside and theres no use trying to ride it like that anyway.
So, winter finally ended here about three weeks ago, so I decide to learn how to change the oil (which im pretty sure i did right) and put some fuel in it via gas can.
Tried starting it up, but the battery was dead. I tried jumping the battery from my car, but it wouldn't run for anything more then a few seconds, minutes at the most. I figured it had something to do with the battery being so dead, so I took it to a place to charge it overnight. Dude says batteries good, hook it back up, and it starts on it own now, but still dies after a few seconds.
What could be causing this? As I said, this is my first bike and im trying to become more familiar with it because, well, I need to be, right?
Any suggestions would be wonderful, and please forgive my ignorance =(
