Default Spark Plug Question
Does anyone know which direction the plugs go in order of temperature? I currently run BR8ES NGK's but I'm running very rich, even at 50:1 (bel-ray mc-1) so I think I should upgrade to a hotter plug, but I dont know whether that would BR7ES or BR9ES. Anybody know?

BR7ES will be hotter. If that doesn't do it recheck the jetting.
