Those pictures are porn.
plain and simple.
please post more.

Wow - total internal carnage.

Given the bike history outlined in the first post, any theories about the failure mode?

I haven't followed this thread, and had my first look right now. Sympathy, never fun, but things beeing what they are, thanks for sharing. Can't find a "smiley" to suit the occasion ....

[jaxduc]

what ever happened?

[Novelo]

Mother of Pearl! You are sure the timing was right? Only thing I could think to cause this unless the guide failed so much to allow it to fall into the head along with the valve. Sheet loads of fun.

Maybe a piece of the guide broke off and jammed between the valve and the seat holding the valve open. Piston comes flying up and BAM.

Good idea sticking with the same motor, gives you some spare parts from your original engine in the unlikely event you need clutch, gearbox, 2nd cyl head etc.

Well it's been quite a while, but I finally got the time to work on the bike.  Here's an update:

Got the new engine fitted to the frame.  Now I'm attaching the swingarm where I have hit my first snag. (Need more shim washers. No idea where to get them).

[jerryz]

dealers should have stock of swing arm shims

This thread is interesting.  All the best.  My engine is dying and wish I had the knowledge to do what you are doing.  My mechanic no longer wrenches.  Trying to have the guts to learn. This thread is encouraging.

The maintenance manual for your bike plus this forum are perfect! Trust me, I knew nothing about wrenching on bikes before this project - and I'm still learning a ton as I go!  I highly encourage you try it! There's nothing you can't overcome with the help of this forum behind you!

Here's an update of my (slow) progress!  I just got the throttle bodies, sprocket, chain, rear wheel, brake, crank case breather, voltage regulator, and various engine electrical controls reattached.  Next I'm refreshing the oil, filter, and spark plugs, then going to put on the exhaust, battery, and air box.  Should be almost ready to run after that!!!



I need some help:  the manual is very ambiguous about the torque specified for the oil mesh filter and the plug that goes over it.  As a result I just made them pretty 'good n' tight.'  Any problems anyone foresees with this approach?  Thanks!!

[Howie]

42 Nm.   'good n' tight.' works if you have the feel.

For both the mesh filter and the plug over it?  I wasn't sure because the mesh filter was barely hand tight when I removed it.

[BK_856er]

Yep, Ducati made it easy here - 42Nm for the oil drain plug, the cap to the mesh filter and mesh filter itself.
