Hi, For few month now I have the following issue, and no mechanic in Hong Kong are able to find the problem. Ridding the bike, when I close the throttle, using engine break, and my RPM goes bellow 2.500, suddenly there is huge back fire from the exhaust (obviously). Watching the display set on consumption (Liter/100km), i can see figures that are moving from 2,5 up to 20 (injection still on ??)... It will stop when the bike is stopped, or if I open the throttle again ... I seems that it happens when it is humid or raining ... Any clue to save my bike ? Thanks
