2000 HD FatBoy, carbureted, stock, 50K miles. If I get on it (coming down a ramp to the interstate) it will start cutting out at 60mph. If I slow down below 60 it runs fine. If I speed back up it will start cutting out at 60 again.
If it is sitting still and I rev the engine up, it runs fine until I get to the RPM that would have been 60 MPH. Am I starving the carburetor, fuel pressure, timing? After sitting for a while, it runs great – even above 60MPH. This seems to be an intermittent problem. But, if I get on it again, I have the same problem.
