Install the cylinder guide pins (A). Install a new cylinder base gasket.



Installing the Piston

Place a wristpin circlip into the left side of the piston.
Lubricate the piston rings and the skirts of the piston with motor oil.

Place the cylinder upside down on the workbench, and install the piston in the bottom of the cylinder by compressing the piston rings in succession. Make sure the mark on the top of the piston is facing the front (exhaust) side of the cylinder.

Installing the Cylinder

Pull the zip tie on the cam chain up through the timing hole in the cylinder, and also place the cam tension lever through the timing hole.

Lower the cylinder/piston over the cylinder bolts, and align the hole in the piston with the hole in the connecting rod.

Lubricate the piston pin with motor oil, and push the piston pin through the piston and the connecting rod.

Stuff a rag into the hole surrounding the connecting rod to prevent dropping the wristpin circlip into the engine.

Install the remaining wristpin circlip.

Remove the rag from the engine, and lower the cylinder until is is fully seated on the engine crankcase.
