Listening your flywheel will give better pickup...can wheel spin in 2nd gear also...BUT when up hill or top end you will suffer...something increase, something need to decrease as well....think twice.
If you listen to your flywheel I don't think you get pickup. hahaha.. but if you lighten it yeah.. but you will lose top speed because the momentum can't keep up due to the light flywheel. Sacrifices sacrifices...
