Bike won't shift into gear and run

Hey folks,
I have a 02 1800C that i took for a short ride last night with no problems. When I got back to put the bike away i had it in idle and went to open the shop. When i went to put it into gear and pull it in it was like i hit the kill switch. Now it won't go into gear without cutting the motor. I've tried going into first and second and no luck, I'm baffled. The motor will start and idle great in neutral but once you try to go into gear it's dead. If you know what i need to do PLEASE help out.
Thanks in advance.
Greg
