| Saw the offending items today.
One with chrome worn right through, one with chrome almost through and one with a chip out of the edge but not on the contact area.
All exhaust openers two rear cylinder and one front.
The rears were the worst so the oil starvation looks the likely cause.
All the others are unmarked.
Ducati would be stupid to sell inferior replacements, so i'm confident they won't need doing again.
Haven't had the bill yet. |
