Engine Armageddon....
 

Just spoken to uncle Nelly who's managed to unearth the root of the problem with my DD engine.

Turns out the generator was loose, creating enough heat to boil the oil and melt any aluminium components within range of the magnets/windings. Apparently it's a real horror story, with that side of the engine full of molten blobs of alloy and burnt oil ("looks like armageddon in there, worst case I've ever seen"!). :o

This would explain the heat being generated in the bores as the oil wouldn't be up to the job of lubricating at the time the engine needs it most. It'd also explain the nasty, nasty noises the engine was making when I tried to start it up again.

Not sure what we're going to do but Nelly's investigating a reasonable-cost option to put it back together and see if it holds.

Ho-hum.

Oh dear!

Mate, I hope you get it sorted out and back on the track quickly.

:o blimey Ali - hope his worship can fix for you mate

C

oh mate .. he did say the oil had been heated up to the extent it now smelt like gearbox oil ......

front cylinder looked ok.

That's about as bad as it's possible to be, isn't it Ali? How long is it going to take to fix? I'm sure in Nelly's capable hands it'll get sorted as soon as is superhumanly possible, though.

And failing that, if you need to raise money ...

I may know someone who might buy your Superlight if you need to sell it to keep the DD bike on the road:devil:

I'm sorry, I'll get my coat ;)

Christ, that's not the news you wanted!

Has Phil got any bits left over you could come to some arrangement over?

:lol::lol::lol:. No.

It looks like the bottom end isn't too bad, so I won't be looking for a new engine just yet. We'll just have to put it back together with new parts where necessary and see if it holds under duress. There is some wear on the back cylinder but Nelly thinks it'll hold up. Shows how good nicasil plating is, a steel bore would've welded itself to the rings a long time ago. The reality is it could've gone at anytime since I bought the bike, and I had noticed the oil getting a bit 'foamy', just didn't know enough to tell whether there was something seriously wrong or not.

So to all other DD big-bore riders, fear not, the kit is fine and you don't need to be too gentle with it, just make sure the rest of the engine's bolted together properly!

Cheers,

Cheers mate, but it's exactly the same lump of metal that had been welded on yours that I'm looking for! Nelly's on the case and sounds like he can source the bits over the next few days.

Cheers,
