Thanks Martin, I actually went through redrilling up by 50micron the pilot and the main jets due to big bore. In addition, I have reset the air screw to 2.0.I am checking the spark plugs and response (still have a slight gap so probably still too rich).Actually, I also went through buying a infra-red thermometer. Did anyone tried that?The idea is to measure the heat at the exhaust connection with the engine. I have set the air screws to get 180C but not sure if that is the right temp. I can see that it definitely reach the 220 which I am trying to avoid. I have actually noticed that despite having all the air screws at 2.0, one exhaust was running at 220C!I think the OEM book provides temp indication for the oil but not so much for the engine. In all case the temp measure is very quick and repeatable without having to open up the spark plugs which can on the long term also damage the alu threads. Any idea what should be the combution temp?Cheers,Marc
