Question about CDI box

[riverview]

Is is possible for a CDI box to work correctly at low RPM but not work properly at higher RPM.

Thanks

Re: Question about CDI box

All depends on the motor you are talking about , some have low speed and different high speed charge coils

Have you put a timing light on it to see if the timing advance is working at higher RPM?
