The Testastretta engines have had significantly fewer problems for two reasons: the redesign shortened the oil galley passages to reduce the time it takes for the oil to reach the rockers (90 seconds for earlier bikes) and a 2001 redesign of the rockers themselves.
Here's Ducati's November 2001 press release:
We'd like to take advantage of the accessibility of the Internet to let you know that for Model Year 2001 (MY 2001) we have fitted new generation engine valve control rocker arms as standard parts in all our motorbikes. The new MY2001 rocker arms are entirely compatible with all earlier versions, starting from the first version of the Ducati 851 model, and are now the only ones supplied
With the introduction of these modified rocker arms, we believe that we have the answer to every possible problem relating to rapid wear of the engine valve control faces. We would however like to remind you of the possible causes of early rocker arm wear:
• Not carrying out checks, which include adjusting the engine valve clearance, as regularly as indicated in the routine maintenance schedule contained in the Ducati warranty booklet. *
• Engine valve clearance not adjusted to comply with the standards laid out in the Ducati workshop manual.
• Use of an engine lubricant that does not conform to specifications indicated in the Ducati use and maintenance manual.*
Since the problem does not affect the users' safety and would not indirectly damage other engine parts, Ducati will not carry out a preventative recall campaign. As always, Ducati is available to answer fully any questions you may have.
