Michael888,just a thought.You are not running the stock air filter I hope.If so you are are too RICH on the fuel.I know dumb question,but you never know. That stock air filter is like a piece of cardboard.I'am surprised they even run with the stock air filters and catalctic converter

mufflers.Maybe they come different down under than in the the USA.Good luck.Your fuel is problably better down there too than here.They have us running this gas that's suppose to help clean the air in the southwest desert.Later.Good luck.
