A new video was posted yesterday of the steam trike I'm hoping to model mine after. His is a three cylinder engine and mine is only 2, but I think my displacement will be about the same as his, assuming his to be 10mm bore and 20mm stroke. Also, his overall gear ratio is about 12 to 1 and mine will be more like 20 to 1, maybe higher.
