The brakes are not stuck. Tires are stock size. The front drive shaft does spin but will not move the bike. The back does not seem to have any power at all. I've been away from my computer. Thanks for your help
The front axle popped 3 or 4 times, then the bike quit pulling itself. The left front axle inner joint had come apart. Just about a quarter inch of the splines were catching. I removed it put the joint back together and it seems to be fine now. The back wheels are still not pulling. I don't know when it started, there has been no problems until this with the front. I jacked up the rearend and spun the wheels. There is a slight bumping noise that sounds like it is coming from the gear case. I pulled the boot back and the rear drive shaft is turning.
