Once the rings are installed, insert the piston into the cylinder. I use a nylon trim tool but everybody has their own methods here.

Next, install the counterbalance weight onto the crankshaft. This one the link rods are tight so I did not replace those bushings, maybe I'll do another write up on that next time :)

Once the counterbalance weight is installed, install the crankshaft into the motor case.

Then, install the counterbalance weight shaft in the bottom of the motor. It seals with an o ring into the block, replace if necessary.
