My post re the Vncent was deleted but there are all sorts of posts re other bikes that are not Commando (I have owned several Ducks). So what did I do that made folks mad?

frankdamp said:So am I, Mike, but for a different reason. In the thread on the Ducati 450 Desmo rebuild, someone asked wht type valve springs it had. As far as I was aware, "Desmo" is an abbreviation for "desmodromic", a valve actuation system that uses cams to both open and close the valves - no springs.
Did I mis-interpret the question or did Ducati use the name with a little bit of mechanical artistic license? They DID make a true desmodromic engine, a 250 if memory serves, but not very many were made.
L.A.B. said:Norton also experimented with desmodromic valve gear on a Manx engine, obviously their system couldn't have been very successful?
