5K Ohms Resistor Plug Cap ?

Featured Replies

Is it better to have a plug cap with 5 ohm resistance or one without, bike is a Cub with PVL ignition.

Yea, well what did you take off? A few systems seem to prefer a resistor due to the electrics, but for the most, this is for RF noise suppression.

When I built the bike the system came without a plug cap so I used a NGK hard plastic type without a resistor but I was now thinking of fitting a rubber type bit more P65ish so wondered if my earlier choice or no resistor was correct.

Resistors do 2 things

One is RF interference and the other is to produce a spark that is shorter in duration and more intense

Resistors are good things

Normal to use a resistor type plug cap with a CDI ignition - you should use one on your PVL.

Don't combine a resistor cap with internal resistor plugs. This doubles the resistance and may give problems especially with starting.

Plugs with resistors usually have a prominent 'R' in the manufacturers code.
