    Backfiring and dying after bird warms up

    Hey guys! I've got a troublesome 2000 Blackbird. I bought it used a few months ago and it ran beautifully. A couple of weeks ago, I was riding and everything was fine. Out of nowhere, my bike lost all its power, and wouldn't rev. It started backfiring and died. I pulled over, started it again, and it started right up. Idled fine, revved all the way up to 12k, so I tried to keep riding. About a quarter mile later, the same thing happened. Whenever my bike gets warm, it happens. I'm absolutely baffled. I had a bad fpr, and replaced it. Still happening. Plugs and plug wires are good. I even did the wire loom fix. Does anyone have any idea of what it could be?

    sounds like fuel starvation if you have no other warning lights etc, here's a hunch

    look inside the petrol tank for rust/corrosion, if so then the fuel pump filter is blocked, if not then I would still be looking at the pump/fuel delivery as the source - when you have the issue put your ear on the tank and listen to the pump

    if the filter is blocked you can blow fuel back through it to clear it temporarily but will block again if the tank is rusty/corroded inside, it happens if fuel is left in there for a long period and unused

    Agree with Geoff it does sound like fuel starvation, another one to check would be breather for the tank, not sure on the blackbird weather its in the cap or not?

    Ride with the fuel cap open a couple of miles. If it behaves it’s likely the breather is shot / blocked

    be careful if your gonna attempt this, you might coat your bike in petrol.

    Or next time it cuts out slowly lift the cap see if you can hear a hiss, the vacuum letting air in.
