Does anyone know how the different plugs would affect performance, idling, etc. As you know there are 2 plugs recommended for the Grom...one is for normal riding and the second is for high speed riding. I definitely need the latter and in fact, have replaced the standard with it, but I can't say I've noticed any difference. Other than the plug firing from a smaller area of the plug, what is the difference?
