Going back to the inlet manifold plastic/metal debate, back in the 80's Suzuki on their bikes came up with TSCC (Twin Swirl Combustion Chambers) Some of the best men in the tuning world took the heads off the first ones and smoothed out all the 'rough as S' intakes..

They then found they had less power, Suzuki advised that the start of the process begins as the mix left the carbs and was finished by the time the mix was compressed by the piston..By polishing out all the lumpy bits in the inlets the tuners had completely screwed up the twin swirl..

Smooth doesn't always mean better..
