[QUOTE="Cowabunga, post: 7478386, member: 718"] The idea that four cylinder engines are not as smooth as six is a load of twaddle. There are out of balance forces in both. Both use different kinds of balancers to ensure smoothness as all revs and loads. Four cylinder engines are commonly fitted with two balancer shaft running at twice engine revs to counteract the secondary forces that occur at every 180 degrees of crank throw. Six cylinder engines almost universally need dynamic balancers on the nose of the crank to counteract destructive torsional vibration of the crankshaft even though both primary and secondary forces should be balanced. If either type of engine was not balanced they would not last long and would sound like a bag of rocks inside a washing machine. [/QUOTE]
