My turn - crash - glass half full...

[stopintime]

Thanks 

After all the mods my bike is quite suited for the track and I'm not sure the total would be better if I had to buy, maintain and sometimes repair another, track only, bike.

[stopintime]

Parts still at several places for repair/upgrades/paint a.s.o. 

Cylinders needed new coating after 80,000 km. Because of some rough running and lack of throttle response, I asked to have the heads checked too.

There was an undiagnosed whining noise after the crash (yes, I shouldn't have let that go unattended) and maybe this is why (picture). Never easy to say for sure, but the bike was on it's side, still running for ~30-60 seconds and I have vertical head external oil feed from the oil pressure outlet.... maybe that feed isn't any good with the bike on it's side

I hate to say this my friend...

but if you toasted a cam and rocker due to a lack of oil pressure you should be looking closely at rod bearings.

I don't think that was the case with the cam and rocker, but I'd still talk to your engine builder about the rod bearing issue.

What side was it laying on?

[stopintime]

On it's right side.

I was suggesting/hoping that my external oil feed was starved without a complete loss of oil pressure, but I don't know how that would happen. I don't know how the circumstances affected the oil flow.

Well...the pickup and pump are on the right side. I don't know if there is enough oil in the cases to feed the pump in that scenario. Maybe Nick knows, or Eric. 2V rockers and cams do occaisionally fail, although nowhere near the rate of Desmoquattro rockers. I'd think that if that pressure fed circuit lost pressure then the entire system would have lost pressure. The rod bearings are far more sensitive to pressure loss than the top end in a 30-60 second time frame.

 When my BMW K1200RS lost oil pressure due to running while  on its side, it took about 5k miles before it spit a rod through the side of the motor. I suppose that is a problem with wet sump engines. Here is hoping that is not the case with yours, but it might be a good idea to check the rod bearings!

glad you're ok

If I close my eyes, cover my ears and hum loudly.... will the worry go away?

If the rod bearings are more sensitive, it's possible that they are damaged even though nothing else is. On the other hand, if nothing else is damaged, maybe the rod bearings are ok too. If the whining noise goes away with a new cam and rocker, there's a better chance the rod bearings are ok. If ifs and buts were candy and nuts.....

These kind of things are never convenient. I see busy mechanics presented with a request for new rod bearings in April/May  Not exactly cheap either. Bright side: rebuilt cylinders and heads go well with a fresh bottom end.

TBC (surely)

~~~SNIP~~~

That's out of he vertical head?

I didn't take the picture, but yes, that's what they said.

80,000kms Lars.

And the news just keeps getting.... ever more condemning 

You know I want to see you succeed here and so I really do hate to say this but......







maybe it's time to cut your losses?

I have thought about that. More than once.

If the rod bearings, and/or more, really are damaged AND I knew that before starting the cylinder/head work - it would have been an easier decision.

At the moment I have commited to the 'new' cylinders and heads, so it's not obvious that a change of direction is smarter. Larger engine with a lower tuning character sounds smarter, but such a direction won't be cheap or maintenance free either.

Just offering a moment's.... sobriety.

Whichever way you choose to attack it....  you'll make it work  

[koko64]

Fingers crossed.

[stopintime]

Sobriety....

With the engine just hanging from the engine bolts, everything disconnected, heads and cylinders off - combined with 80,000km on these rod bearings - it's worth while to split it and inspect + replace the rod bearings and main bearings. Hopefully a waste of time and money, but about time anyway and better safe than sorry...

This clutch started slipping after just 6-7-8,000 km. My usual 30-40 has been with the APTC. Stack height 43,5 mm if I measured correctly. Maybe this standard small wet clutch isn't up to the 'slightly' heavier load... Trying heavier springs or preload with washers. What do you think?

These cases are supposedly from a 2002ss. Searched the part numbers, but couldn't find anything. I guess Ducati only sell complete cases - a pair of halves....
