This kit uses a lightened fly wheel and unlike most other kits it comes with
a crank shaft balancer which must be used for best performance.
This set up will allow your 4 stroke engine to rev quicker and higher.
Inner rotor (stator plate)
Lightened flywheel
Mapped CDI unit (more torque and longer reving)
Balancing plate (for behind the clutch plates for weight distribution)

To be fitted by a confident mechanic !!
