Last night i tried to start my bike and it wouldnt crank. So i took it apart and the plugs were fouled. my bike is a 2001 cbr600 f4i i know its fuel injected why would it be fouling? so anyways i cleaned the plugs off and put them in and it hessitated cranking and when it did it ran like junk. it was back fireing and hesitateing. yall have any suggestion to what might have happened? thanks

 

Has it been sitting for awhile? How old is the fuel?

 

its been sitting without running for maybe 4-5 days...and the gas i have been riding on for atleast a month maybe 2
