I was not at home when I posted the first measurements, they were from memory and were
correct, it's good to see I'm not gone completely senile....
Anyway, a few more:
- Center hole ( to steer towards crankshaft ): 42.02 mm
- Starter ring placement: 14.0 mm up from the crankshaft plane and 272.02 mm diameter.
- Max diameter before the starter will hit the flywheel ( behind the starter ring ): 294.0 mm
The rest is personal preference
