sounds like you for a fuel problem like floosing crankcase with fuel, is it FI or carb

Sounds like bad gas or water in the gas. Could be needing rebuild in the carbs. Start by trying some sea foam in your gas tank.

no! take it back to the dealer

Sounds like it's idling to fast! there is a knob on the right side under the gas tank to adjust the idle.

You need to take off your carburetor , disassemble it, and clean the jets (specifically the slow jet) and the passageways in the carburetor body that feed the gas to the carburetor throat. Carefully set your air screw setting back to stock setting. and reassemble. Inspect the intake manifold and air box tubes for cracks and separations. That should get you idling again.

you need to reset the computer its under your seat there are 2 plugs by your fuse panal just unplug them and plug them togather turn key on wait 7 seconds them plug them back up right
