Putting the puzzle back together

Now that all the parts are clean, it is time to put that engine back together, first I heated the block and using a new bearing, installed the bearing and sealed it. The new bearing is a double-sealed so it won't need lubrication unlike the old one on this picture

New set of gaskets will find their way on the engine block

The block gets the crank shaft and side plates that attach the engine to the bike frame:

Piston is installed and the cylinder for fitting before closing the case with the oiled gasket

Here it is with the engine top end and gaskets secured

View from the other side with the rolled installed, the long screw is preventing the crank from turning when tightening the bolts securing the roller and the clutch

And here is the clutch
