After a bit of research and contacting NGKs tech help department, I thought I'd fit an Iridium plug to my bike and squeeze out a little bit more power from my 400cc single (as I had done with my previous 500 twin). Straight away the tick over has gone up slightly showing better combustion and the rides slightly smoother too!
