Stage6 racing cylinder is 10mm and 12mm pin. (2 types)
Hebo Manston replica is only 10mm pin.
If you will fit these cylinder , I would recommend 10mm pin crankshaft.
RMS racing crankshaft (10mm pin) is very cheap and good quality.
You can get RMS racing crankshaft and Stage 6 racing cylinder in 250 euros.
