ok I have a 79 jag 340 I have restored most of the sled It boggs down when i have the head light plugged in. When i unplug the headlight I have great throttle responce and my plugs keep fouling out. It also has a hard time idleing it is oil injected i have cleaned the carb it is a mikuni and i have rebuilt the fuel filter. I know the voltage reg works its new I have also checked the voltage and it is around 12 volts I am pretty much lost from here on in so any info would help a great deal
thanks mike
