Im pretty sure your bike is fuel injected. You need to look between the throttle bodies and the intake manifolds to the cylinders. If you spray the area with WD40 while the engine is idling, and the idle speed changes, then the spray has hit an intake (vacuum) leak and sucked the fluid in like fuel.
check any hoses in that area, and the caps on the short tubes you would normally attach a vacuum gauge to. Sometimes those crack or fall off.
