ethanol sucks and is probably the culprit. from what i understand the tanks were supposed to be cleaned before the new ethanol mix was brought in. so how likely does it sound for that to be done? i had issues when it was first introduced last year. now i make sure i go to bigger type stations that i know, or seem to have had new tanks recently.

also try the cleaner that yamaha makes. its called piston cleaner or somthing like that. im sure if you were looking at all the fluids at a bike shop you could figure it out. any way you use about 2oz regularly to keep it clean. or like 10oz in one tank and then you have to change your oil after that tank

also you can set your idle speed higher. mine is at about 1500-1700rpm
