Ok if building a good street/performance motor and have a respectively light flywheel do you need counter weights? most people add weights to smooth out vibrations caused by weight of stock flywheel on crank/flex and main bearing stress, but if weight is greatly reduced from flywheel you gain smoother rotation forces? plus with no weights on crank less stress and force?energy/Horse Power from pistons.



Yes everything balanced individually then as one mass. pressure plat,flywheel,crank,pulley so if balanced properly do we need counter weights?



cheers guys
