Default Help Please?

So, I figured out that there needs to be a bearing replaced in my 99 RM 125. How do I open up the crank by myself and replace the bearings? It will cost $1K to get it done through a mechanic. Does anyone know step by step instructions? I've fried 4 stators and spark plugs not knowing what the problem is and a bad bearing seems to be the only reason. My bike runs good for like an hour and a half and then shuts off : \ Can anyone help me out? Thanks in advance!
