Hello everyone, I have an 09 Speedster 150 with a 215hp motor that has 78hrs on it. It was dealer serviced at 72hrs with an oil change, new plugs & general pre-season checkup. The motor runs smooth at idle (about 1,800rpm) and any speed above 2,500rpm with no hesitation going to WOT. However, it does have a surging problem when I move the throttle just off of idle (the motor will constantly surge between 1,800rpm and 2,400rpm). If I keep increasing the throttle the surging will stop at 2,500rpm and run smooth again. Has anyone had this problem or know what is causing it? Thanks for your help.
