[QUOTE="Donal, post: 1108486, member: 20675"] This is a recurring theme. It has often been described as a 'semi flooded' syndrome because that is just what it acts like. It usually occurs if the bike has not been allowed to warm up after a longish shut down. However, this condition seems to persist for weeks or even months after the initial short run. I am beginning to think it's something in the ECU. My SWAG is the ECU is programmed to overfuel during the initial cranking period. Something tells the ECU that a satisfactory start has been achieved (who knows what that is), and then the ECU is reset. If the bike doesn't run long enough to 'reset' this condition then it remains in static memory until the next attempt. It may even accumulate an additional overfuel signal (some sort of stack memory)? I have no idea how to verify or eliminate this idea but I do believe it is electronic............................... Oh! and just in case anyone thinks altering the ECU to eliminate this annoying problem is easy, have a look at the first post in [URL="https://www.rswarrior.com/forums/13-technical-discussion/151881-mitsubishi-ecu-warrior.html"]this link[/URL] [/QUOTE]
