I would assume that your starter clutch (located behind the flywheel) is bad.

Dont ride your bike untill you get this fixed!!! My 03 did the same thing and I was lucky to get it before it came apart. The flywheel can be pulled off with several pullers, use the Yamaha one. The flywheel was Loctited on and you will need heat to break the bond. I use a propane torch to heat the flywheel center only, it will be hot. Check your owners manual and good luck.

I think it is the starter clutch....doesnt look like a big deal to replace.
