I agree on Naraku being a good company. I'm confused also but the dealer did originally put in an unrestricted CDI (power kit purchased from Racing Planet) and the scooter did not run well at all. That's why he reinstalled the OEM Kymco CDI (which is restricted) and the scooter runs great. But the top end is only about 33 MPH on flats even with the derestrictions he did for me which was installing a smooth variator boss, removing the intake restrictor, insatlling 5.5g slider weights and rejetting the carb.
If I can get a unrestricted CDI to work I'm hoping for at least a 5 MPH increase.
