PLZZZZ HELP I Just bought a 2009 Kawasaki Brute Force 750 and its not working the 1st TIME out! What do i do?

you said injectors .injectors need a fuel pump. loss of fuel pump pressure will lean it out and it will get real hot on the header pipes .run like stink also.need to find out what fuel pressure should be i guess 30psi.hope you didn't blow a head-gasket by overheating . you test fuel pump at output side or where it goes to injectors .might be electronic pump .follow line from tank see were it leads to .make sure it's not plugged up in the line, filter etc with some sort of junk. also lines shouldn't have screw type hose clamps for injector stuff.pressure makes them leak depends on how much pressure.
