HELP???
It more than likely is because your bike is jetted just right for having the lid on.... Taking it off decreases the resistance to air flow, meaning more air which in turn means less fuel which spells "Lean".
I know nothing about Raptors, but if the hose is what I think it is, it comes from the motor.. it is a breather hose that allows backpressure - any pressure in the crankcase to vent to the airbox.. plugging it will cause pressure in your motor and potentially blow seals.... DO NOT PLUG IT.
