I am having a problem with the new bike. When I try to take off the bike dies unless you give the bike a ton of gas and let the clutch out really slow. One it takes off it has power and runs great but I'm stumped the clutch isn't slipping but is kind of hard to pull. I don't think it needs to be replaced but what can I do to fix it's take offs. When I nail it off the start it spins the tire a little then boggs and dies. I can't figure out what's wrong.
