4age Bigport - Twin Sidedraughts

[Philbo]

Hey people,

Just wondering about the effects of removing TVIS from a bigport; it's supposed to make it doughy in the low end due to reduction in air velocity right? So can anyone tell me if this is evident while running twin side draughts?

Thanks,

Phil

When you put carbies on the air velocity is different, What i did was put a tvis plate on that had the butterflies removed, Removing tvis from a 4age does not have a major effect on the engine anyway.
