Two stroke or four?[edit]

Some additional info about basic things like whether it was a 2 stroke or 4 stroke engine would be useful. When it doesn't say otherwise one usually assumes a four stroke, but then when one sees "one valve per cylinder" without any further explanation, it makes one wonder. I have never heard of a 4 stroke that didn't have at least two valves. Sleeve valves, ports, these are all things. 2600:1000:B158:BAFB:0:5D:244:B101 (talk) 18:07, 25 December 2022 (UTC)[reply]
