Hello all I have a 1984 Honda Magna VF700 that when the rpm's under a load reach appx 5500 it starts to sputter and will not accelerate any further. I have cleaned the carbs,fuel tank and changed the fuel filter and still has the same problem. I checked the fuel cap vent and it seems to be fine. I had it running and noticed that there was fuel coming out of the fuel cap and after opening the cap it appears as if there were tiny air bubbles inside the tank fuel as well while running?? I would appreciate any help I can get on this one have never experienced this before.
