Alright I have a question.. So has anyone with a gs400 use an aftermarket coil pack or know of which ones fit for an upgrade. I work at oreillys and seen some accel coilpacks. They say the add about 10hp that would be good too but I am looking for a better spark. I was thinking of modifying my coil pack plugs to accept these. has anyone done this?
