Right so as promised a table highlighting several concepts for Bore and Stroke with a 1mm incremental scale on the stroke size. We can quickly narrow down our potential bore and stroke sizes as anything smaller than a 40mm stroke is illegal with regards bore size and anything above 45mm creates an unrealistic mean piston speed. n.b. remember the cylinder capacity is relatively small on these engines so we will need to rev them to create power so reducing the RPM to a reasonable mean piston speed is not necessarily the answer. But again it's all a compromise.
You could now check sizes in between the strokes given to optimise your design but I'm going to leave it there as there is so much to go through regards port, head, camshaft design etc.
