    Fatboy 08 stalling at lights when dethrottle ????

    Hi All

    My fatboy 08 has begun stalling or beginning to splutter and stall when I slow down to stop.

    Can anyone help?

    try putting a bottle of redex in tank and ride a fair distance to clean injectors and sensors if bike is stood a lot modern fuels go off and leave a residue in fuel system as petrol has a limited shelf life

    Thanks, some people have mentioned the throttle body or the engine temp sensor?

    What will redex do? Is It just poured into tank

    redex cleans the fuel system as it runs through mixed with the petrol after putting it in the tank it cleans the sensors injectors lines manifold ect there is a noticable difference

    Thanks I took your advise on the redex and cleaned out the air intake, it definitely made a difference. When I cleaned out the air intake fap (not sure term) there was oil on the out side of the flap.. Took it to harley Chester and they said may be mushroom / seal which is in the top of the head of engine.. Does thatsound familiar?
    Thanks Gareth

    stick another bottle in and run another tank should feel different again did my mates heritage this way worked ok after that you often get traces of breather oil on older bikes as harley insist on venting heads into air cleaner adding oil mist to fresh incoming air to to remix and bring emissions down i tend to divert breathers on my bikes
