Pretty normal for a bike if it sits too long.
Pull the float bowl cover and inspect for any white, brown, or green corrosion.
White is water, brown is old fuel, and green is ethanol and water.
At the very least you will need to replace the pilot jet and spark plug, and do a vavle clearance adjustment.
These bikes come set up very poorly from the factory, and if you want it to run smooth and consistently, you will need to do some reading up on the uncorking and rejetting, and possibly the dissconnection of your TPS and ACV systems.
