Snowmobile bogs down at full throttle?

I have a 1996 Yamaha Vmax 600, it moves along just fine until i go to give it full throttle. I could be moving along giving it 3/4 throttle and as soon as i pin the throttle to the handlebars, the rpms drop until i let off the throttle. It operates perfectly at less than full throttle. What is causing this?
