Default Crank Pulley

I know that crank pulley does give a pretty good amount of gain but I remember in the past, someone told it is not a good idea to put a lightweight crank pulley on an engine that's being driven daily. It can do some serious damage to the motor. I forgot why though. Anyone here experience with crank pulley?

the 1.6 and larger engines use a harmonic balancer type crank pulley to reduce vibrations. a lightened crank pulley does not have this feature. so in the long run you may end up damaging your engine. now a 1.5 does not use a harmonic balancer, so you could use a light crank pulley but you 1.5 pully is already light weight due to no rubber damper.

I don't quite understand about this. I still don't understand how it would damage your engine. Can you explain it to me more about this? Thanks.

a harmonic balancer/damper dampens harmonics which cause vibrations. the 1.6 uses these as the vibrations can cause your #1 main bearing to absorb the vibrations thus causeing bearing damage.

Which other Honda comes with a harmonic balancer? Do you know if the H22A engine also comes with it?

Most engines made have harmonic balancers.. A lot of the time the pulley and balancer can be seperated.
