Over the holiday period I've been carrying out the 6,000 mile service on my ST4s. As well as measuring the valve clearances I decided to take all of the shims out whether they were out of spec or not so that I would have all the baseline measurements to work from the next time.
Just as well I did. As it turns out the horizontal left exhaust opening rocker is showing signs of the hardening flaking off
and the clearance for this one was well within spec.
If I had had a dealer do the service they would probably only have measured the clearance and left it at that since it didn't need adjusting, although that would depend on the dealer I guess.
Anyway, before I go off ordering another rocker from Ducati does anyone know if there are any specialists in the UK who re-face Ducati rockers, preferably on an exchange basis.
