Here are some quick notes I made for all of you that dont know how to take apart a 4 stroke top end. This is the only way for sure you are gonna know what size engine you have. You can speculate all you want but the truth is only in the bore and stroke. This is a rx12 110cc engine, but the instructions will work on all single cylinder ohc 4 strokes.
Take apart your engine at your own risk, if you mess it up it is your fault.
Cam timing is very important, you do not want to screw it up.
