Drain the oil and see if any teeth fall out. That will give you an idea whats wrong.
If there are no teeth  it my be a loose selector drum.

Your RM has a constant mesh transmission and I'll bet that both the shift fork,third gear and the other gear that the shift fork moves over to engage 3rd gear are all toast. Time to split the cases and spend some money. :-X
