Has anyone got any advice on the best plugs to run on a modified engine? I' m currently running NGK BP6HS. These make the engine easy to start but seem to be down on power at high rpm, compared to the champion plugs I use before, which kept breaking down. It has been suggested that increasing the heat rating (cooler running plug) would give better top end pull.
Anyone already played about with this, as changing the plugs is a pain, so only doing once more would be good.
This is my 10th post, in to double figures now; I can tell you' re impressed.
