We have swapped servers recently. Is it working for you now Ranburetta?

The megaphone exhaust is interesting, I think. The Vespa race scoots have them as well. They were the performance exhaust of the time.
Then someone decided to quieten the exhaust down by adding a smaller pipe on the end of the megaphone, effectively adding a second cone and accidentally inventing the expansion exhaust.
Imagine the conversation: "Yeah, it's quieter, but it goes like the bloody clappers".
I wonder if an expansion on this would have made a significant difference?

1951 was probably the first year expansion chambers were seen in the racing world introduced by ze germans, but they were very much at the head scratching stage until Walter Kaaden came along. This guy revolutionised 2 stroke exhaust dynamics from 1954 right up until 1976. Much of his work was an iron curtain secret until it was revealed in 1961, I think, and that's when Suzuki got involved.
The Suluro used brute force supplied by a Supercharger to fill its little combustion chamber with highly volatile fuel......Exhaust dynamics didn't matter really.
It would be interesting to see what a custom designed chamber would do for it now with the right carb though?
