About 2 months ago I was pulling up in my yard and my exhaust broke and fell off and it broke a chunk of my right side crank cover off that the exhaust bolts to. Now I have looked for videos and other visual repair to replace this part but alas I can not find anything for a 139QMB other than to change the stator. I do not want to break anything as this is my first time replacing this part. If anyone could show me a video or lead me into the right direction for visual that would be great.

I have been looking for a rebuild kit for my 49cc Jonway. What I have found are BBK upgrade kits that are cheaper than that 49cc rebuild kits. So is it worth rebuilding to a 100cc BBK? My 49cc is burning oil like crazy and I don't want it to seize up on me being I ride it out of town quite a bit.
I have a few BBKs on watch on ebay ranging from 40 to 150 dollars.
I also have questions about changing the oil pump on this as well being I cant find a video of changing the oil pump at all.
