Introduction: Splitting Crankcase on Small Honda Dirtbike (XR80 Etc)

The 1998 Honda XR80R used in this example will be extremely similar to the XR100, CRF80, CRF100 and more. Don't ever be afraid to work on a simple little motor like this.

Please be aware that this is a 4 stroke, a similar video on a 2 stroke would be much different as the smallest leak in the crankcase is a much bigger deal. Therefore I do not talk about the seals etc.

This is my first post here so please forgive the lack of detailed "instruction" in my wording.
