I just bought a f4i that cranks over but does not run. Has no spark and no fuel but my fuel pump does turn on when i jump out the relay so i know my fuel pump is good.
The guy before me had a ebay streetfighter headlight on it that he said started smoking from the headlight wires so he ripped the headlight the bike at the stunt spot an it has not ran since. My question is how can i bypass the bank sensor from the grey plug were the whole front headlight harness is supposed to plug into. EVeryone says to just cap off the white wire and connect the red and green but i dont see those 3 colored wired anywere at the front of my bike. Someone help me out please
