Morning all
Is the flaking rocker arm a problem in the 996 ST4s engine?

[nelly]

Possibly. Generally any of the 4 valve motors are prone to it, although the newer the bike the more likely it will have the "new" spec rockers in.
These still go but far less frequently.

Cheers mate ...what do you consider newer? ...mines a 2001

[nelly]

Can't really tell witout the original part numbers to be honest.
Ducati have issued three or four new numbers for these parts now and there's no way to tell them apart visually.
It all depends what was in the parts bin when the bike was assembled. Assuming you haven't had any changed already.

Thanks mate ...well at present the bikes in a container winging its way to NZ ....should actually be there now !... so I will have to check them out at the 6000 service ...i had to drop the oil to ship it and there was no sign of metal flake so fingers crossed they had there hands in the right bin !!!
