all you need is the parts, metric socket drives, metric wrenchs, allen wrenchs,etc. and a torque wrench.
the cam is a drop in.
the rod will work with the 10:1, but you should check it to make sure the bearings are in good shape.
you will need to take the cylinder to a machine shop to get it bored and honed.
you MUST have a CLEAN place to do the work.
and get a manual so you can do the rebuild right.

I would recommend getting a clymers manual if you don't know what you are doing. It might save your motor and would be nearly as valueable as the cam and piston.
