Talk:Poppet valve

From Wikipedia, the free encyclopedia

I'm not sure about auto racing engines, but the previous edit may have made it sound like the highest speed (or most, or even many) motorcycle engines used desmodromic valves, when in fact most of them do not (anymore, at least). Ducati certainly uses them, but equally or higher speed engines from Honda, Suzuki, Yamaha, Kawasaki, etc. do not use desmodromic valves. My edit changed "very high speed" to "some high speed". Shiny side up. -- Ds13 06:54, 2004 Apr 9 (UTC)

[edit] Flat Top

The Chuck Berry song,"You Can't Catch Me", contains the reference to a competing vehicle, as in: "Here comes a flattop, he's movin up with me".This line is changed a bit in the John Lennon version of the song, which is to the same,slower tempo as the Beatle's "Come Together" line, 'Here come 'ol flattop, he come groovin up slowly'.
