Oh, PGkelly I actually forgot to note, do you know what the maintenance on a Ducati is like? Ouch. Something like every 3,000mi the valves need to be checked because of their unique valve closing properties. Although it's rare to see them out of adjustment at that point, it's been seen before.
While I personally think it's a really cool system in theory and to talk about, I don't really think it's practical in high mileage engines you find in cars. They would need to come up with a much less variable system before it could work. Actually Ducati's are on the wee bit side of finicky too. Like actually on the way bit side of finicky when it comes to adjustments in their valvetrains. The maintenance costs with the current system exclude this technology when the current systems in place already perform adaquately, if not good.
