Okay I got the bike back from the shop and my friend rode it home. After we got home we shut the bike off and later on tried to start the bike up again. It didnt start, we pushed start it a few times and it started right up. Shut the bike off again and it wouldnt start. We figured the battery. My lazy butt didnt get around to get a new battery until 3 weeks later. I put the new battery in and I would just hear the starter but the bike wouldnt turn over. My friend told me to shake the bike a little because there might not be any gas in the fuel pump. After I shook the bike a little it started up but once I let go of the throttle it dies out. I put the choke on but it still doesnt stay on. I highest it will rev to is 5k but the bike will still die. Im new to this bike scene anyone have a clue what the problem might be. Any help would be appreciated thanks.
