my 500cc 1955 bmw bike (boxer 2) doesn't have a crank balancer, and the 600cc model from the same era didn't, but the 600cc sport model from then did. slightly different valve and ignition timing, slightly different stroke maybe, higher compression. higher rpm? dunno, they didn't have tachs back then.

Ola posted:So much interesting stuff! But this one: that is seriously disturbing. but i can't help wanting to know...scavenge air receiver? does that mean the 2-stroke transfer ports?

Splizwarf posted:I blew up the photo and it's the air chamber on the exit side of the scavenging operation. Reads like he was knocked out/killed by fumes before he could have been pressurized/burned. right, but "scavenge"? i've only heard that term used in the context of 4-strokes. is this another word for something else or is it a function unique to these marine engines?

that was most certainly not a mechanical failure, though

If that video is any indicator though, the Dutch are a little behind us in tractor awesomeness. I mean, a single i6 engine? Ours have like multiple v8s on every tractor. Get your poo poo together, Europe.

KozmoNaut posted:I don't think any motorcycles since the 1950s have called for straight-weight oil, shared-sump gearbox or not. And my understanding on why they use straight weight oils is that they lack rubber seals on their valve guides, so multiweight (lighter when cold) oil would leak past the guides.

I thought only motorcycles could do that. Is that an alignment issue or what?

Heard a motorcycle tire explode once from overinflation, I couldn't believe how loud it was. Sounded like a 12 gauge.

That truck rolled? And only minor injuries? drat, that's a nice outcome. And you took out a PT cruiser, too, I'd say that was a pretty good day overall.

Why would you ever want only half the water jacket filled with cement? You're blocking all the coolant passages either way, why not fill it up and get more rigidity?
