Not strictly welding but I thought there might be a few who would find my Condor interesting, and potentially a few who know a or two about Ducati engines .

were bikes built by for the Swiss military, however the are just re-badged Ducati drive 350 singles (no desmodromics. ). were in use until 2001, I am the first civilian owner of one. Registering it in the UK was a bit of a nightmare, but all was sorted and I had a few thousand miles of free riding. Well the (lack of) charging took getting used to, but I think is just what old bikes are Aside from that I had a time doing all the things one does with a bike;

Collecting produce from the

Transporting outboards and so on .

Anyway, I was back from a days on the van and the engine cut out a couple of times, for a few each. Sounded to me just it was running out of fuel, so I switched to the and carried on to see if I could make it Kept going for a few hundred then suddenly the engine seized. I managed to gather my and pull the clutch in, but I was already sideways on a muddy country by this point.

No damage to me (only going and modern bike gear is and the bike only has a bent and scratched pannier. However a engine is rather more and those Ducatis can be rather from what I hear!

I am at university now, and have the engine with me for when I get fed up of lab reports.

I am not entirely sure changes Condor have to the original engine. An external oil has been fitted, and the exhaust looks a little bodged if I am however I don’t know if is a Condor modification or a later The compression ratio is supposedly (8.5:1), but the head, piston and all look original Ducati to me, and are no particularly thick gaskets.

Anyway, I decided to tear it and see how bad the damage was.

Just had to and admire every now and again, it is a beautiful engine.

The head and slid off without a problem, in a way was worrying as a new piston / cylinder isn’t the end of the world, but a new con-rod for engine is over £600!

I carried on. I had loosened some of the looking nuts with the still in the frame, but I had missed the nut the output sprocket. Bearing in I had quite a good go at freeing the previously, rocking it backwards and in gear, trying to turn it with sockets and so on, imagine my when trying to undo nut and the piston poked its head out of the

An improvement for sure, but the big end was definitely the of the seizure, still very I have no idea why it decided to up then all of a sudden.

There’s the cover off, I am waiting for a puller to continue now, arrive early this some time. Hopefully I be able to see the full extent of the with the cases split. The had plenty of oil in when it seized, and I had frequently changing the oil, so I know what caused

The oil pathways split immediately the pump, some goes to the big end, and the remainder goes up to the so I don’t know if just the pathway got blocked by something, or if the oil failed. Hopefully further will answer that. to say, oil temp, oil pressure and CHT are going to be among the first to the rebuilt engine!

There is a covering of metal flakes the sump, presumably the remains of the big also presumably what has this scoring of the piston;

there’s the story so far. for the distinct lack of welding, but be sure to post plenty of if I do have to do any, and I hope people find this As ever, and advice / recommendations be greatly appreciated, I don’t have much of a clue I am doing
