This is a summary of Honda PA cylinders.
I know it's not much (Not nearly as complete as the Puch summary) but it's a start.
You can make this better by adding your own experiences, adding timings, port shapes etc. Look at the Puch wiki and be inspired.
50cc Stock Honda
By far the most reliable cylinder. But it's also by far the slowest.
Fast 50cc with bigger ports than stock cylinder. Pretty rare.
Good cast-iron cylinder. Out-performs the stock Honda cylinder, but just slightly.
