Well, yesterday I was happy riding my Corsaro, having just fitted the Moto Morini gel seat. The seat is great, a bit taller and narrower than the standard item, and looks great with the red stitching like on the Granpasso. However, as I parked the bike it smelled of burnt oil...
I noticed my left foot was well sprayed with oil, and the rear tire was also covered. Since I had not noticed anything while riding, I can only assume the leak must have happened just before I stopped.
On closer inspection I found that it was one of the pipes that goes from the crankcase to the oil cooler that had ruptured from rubbing against the crankcase! Starting the engine saw oil pulsating out of the breach.
A friend with another Corsaro came over and we looked on his, and found that his pipe is also rubbing against the crankcase, and probably risks the same issue. So, now I need to replace the tube, and find a solution so that it is not against the engine.
Has anybody else experienced this problem?
Serious Oil Leak
I was looking at the oil cooler recently and was surprised how amateurish the fitting of it is.
The whole thing pivots too easily for my liking.
Doesn't seem to be fixed securely at all.

I am not so much bothered by how the cooler is fitted. Actually, the fact that it does pivot as easily as it does probably saves it because of the vibreation it would suffer being more rigidly attached to the engine.
The problem I have is with the hoses. They are attached up against the crankcase, and the obvious rubbing has led to the repture. It was similar to how the brake and clutch hoses were attached up against the head stock when I got the bike. This not only dents the hoses, but would also probably lead to a breach at some point. I had those two moved away from the head stock right away, but unfortunately I did not really pay attention to the oil hoses...
Since I am planning a long ride over the up-coming long weekend I am a bit bummed now. I must get this fixed this week, and would prefer to get some steel braided hoses in place. Then I know I will be worrying about this all through my up coming tour...
Oh well.

Henrik,
Sorry to hear of your problems I have a Veloce and will see if the same problem applies, as you say the oil cooler is very flexible due to being mounted only on diagonal supports, braided or silicone hoses are the way forward, did you know that you can buy the stainless steel braid to go over stock hoses and they supply special enclosed jubilee clips (anodised in different colours) to secure and tidy the ends.
I am going to see what Samco hoses do in their silicone range and will post my findings.

Looking at the pictures, I realize there is more than one design flaw here. The plastic clamp seems to have also chewed its way well in to the other hose, and I would say it might need replacement soon as well.
If the metal 90 degree bend seen in the foreground was actually more like 70 degrees, it would bring the hose away from the engine and also avoid the plastic clamp rubbing the other hose. This all will require a re-think.
Now the really bad news is that I can't get a replacement until next week, so my tour through the Alps to Lugano and back seems to be cancelled. I guess I can spend the time to try and find a better solution, probably using some steel braided hoses.

Henrik;
Glad that you've been able to sort your leaky pipes out!
I had a similar problem with my Dart back in the 90s - the pipes were partially hidden by the fairing and rubbed against the corner of the crank. It seems that this is one small part of the design where Lambertini and colleagues have not learnt from past experience (or is that herasy?). One for other Dart riders to look out for too, as loss of oil is never a good idea!
Having had that experience I have very slightly modified the pipe routing on the Corsaro to ensure that the pipes clear the crank - moving the plastic clip upwards also helps stop the chafing of the pipe at the union as shown in your picture. I understand that later machines have had a small modification in this area?
I'd look to post a picture, but currently the Corsaro is at the dealers having a chipped valve - resulting in a loss of compression - replaced under warrenty...
Have a good run through the Alps and let us hear about the trip,
Good riding,
CC
