I have a pgo big max 90 (I believe). Top end destroyed. It seems it is a minarelli 90 horizontal. Can anyone confirm if any of the millions of cylinder kits will fit directly. Exhaust port orientation different to all(slants right to left). Piston is 50mmdiam and12 mm gudgeon.cylinder studs just over 70mm.
