I think Walenut makes a valid point here. Although statistically I'm in the "had rockers fail" camp, I think one rocker in 40000 miles is pretty acceptable! Especially compared to some other posters' experience.

Rightly or wrongly, I've always felt that it's largely because my bike is used (almost) every day, whereas I guess many Ducatis go weeks, or even months without being started, especially in the winter. Surely this ties in with the "oil maintaining a film on the rockers from the last use" theory? [/quote]
Well the proof does seem to be in the pudding, regular use and only one rocker in 40,000 miles.
