I am a newby to this forum and hope someone can help.<br /><br />I have a Suzuki 1996 DT115 EFI that just cuts out after cruising @ 4000rpm for a few minutes. On restart(which take a few goes) it only runs on 3 cylinders but seems to run on all 4 for a brief time if the throttle is opend wide before cutting out again. It did cruise after stopping the first time OK @2800rpm to get me home.<br /><br />I have checked fuel supply - seems OK<br />Checked spark - seems OK<br /><br />Three spark plugs are the correct colour, the 4th is very grey with some white spots in the electrode. that is from # 3 cylinder.<br /><br />The motor is not overheating, the battery is new(checked it state of charge again), there were no warning buzzers.<br /><br />Motor has done an easy running 380 hours.<br /><br />I just don't know where to start but naturally am very worried. <br /><br />Can anyone help me?<br /><br />Tomsuzy
