Carby Foaming from vibration

yes the engine vibration can cause the gas in the float bowl to foam. You can lessen vibration to the frame with rubber between the engine and the frame but that doesn't stop the engine vibration. And a solid mount to the frame causes the frame to absorb all the vibration till sometimes they crack. The best solution is to drill extra balance holes in the crank wheels: www.dragonfly75.com/motorbike/vibes.html
