Expansion chambers for two-stroke engines are another very interesting subject for some of us here, so I got a question :I have seen several software programs that can calculate two-stroke engines from 50cc and up, but never any for smaller engines - so do you calculate your own or is there a program I haven't seen ?By the way - very nice looking system you are building in the pictures above.
