Would a single common & low volume plenum work with such very short primary lengths?

Not really. That common plenum would act like a Honda ATAC volume. In the Honda system this volume is closed when it is not needed; in your situation it will always be open, weaking all pulses all the time.
What you'd need is some rotating device that couples an exhaust port that is just opening with an exhaust port that is about to close, while the third exhaust port is open to the atmosphere via a sucking (loud!) megaphone.

The only benefit I saw on the GT750 3into1 chambers was reduced weight. It was still a pig.
As we also had RDs, we spent the bulk of our time working on them as proven modifications and parts existed.
When the watercooled RZs came out the RDs were relegated to errands.

I am unable to upload any pictures. But I had an interesting bike on the DynoJet dyno today.

An AG100 farm bike. Single cylinder two stroke with twin expansion chambers that made 27 rear wheel hp at something like 11,000 rpm.

10 carrots, it's not you Rob, its KB. or at least an interaction.

Curious....

Do you mind sharing the ignition curve you are running?

Not at all, if I could only post puctures.

This is a workaround I have been using;

Upload the image here: https://imgbb.com/

Then post the resulting link within your post, like this:

And it looks like I can do the work around ApolloMotoMoto suggested. But you have to click on the link to see the image.

There is possibly a KiwiBiker work around too. https://www.kiwibiker.co.nz/forums/m...bbcode#imgcode

The shape of that curve plus AG100 handling should make for an exciting ride.

I'm assuming that's the pre-powervalve cylinder.

Is is still 100cc? Seems like an awful lot of HP.

[Flettner]

127cc, rubbish 48 x 58 , stroke and bore.

Hence the broken foot.
Yes, still my orginal air cooled home cast none powervalve cylinder.
Water cooled powervalve one got held up at NZ Cylinders before Christmas, wont see it until after the 13th.
