Crankshaft size on 1954 Morini 175 Turismo

[MarkZ]

Hello
New to the forum, I recently rode the 1954 Morini 175 in the MiTa this year and now it needs some work.
I want to overhaul the engine and am wondering about the size of the crankshaft, also the numbers for bearings in the crankcase and may need piston and rings.
Also any shop manuals, that would show splitting the cases, the bike has a tendency to go into false neutrals. I have the owners manuals, thank you.

Hello Mark,

I do know a parts catalogue exists, but not a workshop manual.
You could contact Cesare Resta in Italy (excellent English) for such a catalogue. If anyone, he should have it.
