@afiq: Next weekend I'll try that too... great explanation.. I think I need a pitman PICCO graduated... lol

@burrito: "If engine feels great for the first 2mins already, you're definitely too lean and this may turn into a problem after 15mins or so" ... I had this feeling...may this was the problem...
