Ouch : some trouble… Why? :-x

Here are the problems:
The pistons were tight.
The camshaft carrier move.
The tappets have a mark more than 1 millimeter

How it happened ? Some assumptions :

I think it should not put the last segment on the pistons when the housing baffles on crankcase are in good state.

For the axes of camshaft. I think the exhaust valves are too long. Once when the spring is fully compressed background downforce refers to the axes.

If someone have an idea?

Harley JDH : Replacement of cylinders

The engine is on the bench.
I want to replace the cylinders which are 1927-1928 models by 1929 model.

But… It’s no so simple… 😡
