Re: weird idle problem f4i

does your FI light come on when this happens?

Do you still have your STOCK idle cable hooked up? What happens if you turn your aftermarket idle cable all the way down, does the bike idle properly at 1100-1500?

Is your battery good and charged? NO push starting!

Re: weird idle problem f4i

where would the fuel filter be and i dont think its a fuel pump cause it revs fine at high rpms and that usually where you notice a fuel pump goin out
