Doubtful. I'd guess with the plug being lower in the button and maintaining the same head clearance you stand the chance of the engine burning the plugs out and also a risk of pre-det which will damage the piston, head and plug. I'd stick with the os plug as per manual or os plug equivalents. I run novarossi and so stick with nova plugs. Others may do something different but it's rarely a case of just changing one thing it's usually a combination of things.
