When I worked for toyota I once sold a fog light where the part name on the packaging said FOGRANPU.

In BMW manuals, allen head bolts are called fillister head screws.

Honestly though, look at that bolt. No rust or nothin on the threads, nice and clean. And it was big enough to get a big ezout in it. Commie ain't all that.

I think we saw that once on an XS750. If I recall, we tapped out what was left of the old B plug and installed a D plug inside it. Worked like a charm.

Haven't had one burn out yet on my '68 or my '65 Mercury in 6 combined years. Ford's headlight circuit breaker headlight switch tripped all the time, though, until I put relays in. It was not designed for halogens.

I dunno what's going on with those cars but I see them blown out on old bikes all the time. Except they're not blown out from any excess current, and you can't see that they're blown out, because they're disconnected inside the metal end caps for unknown reasons. And the socket connectors they snap into frequently break.

Warranty flat rate time ?

Back when I was in BMW bike school there was a warranty recall on some of the new S1000RR bikes where someone at the factory forgot to put loc-tite on the con rod bolts. The tech bulletin said BMW would pay the dealers for 7 hours of labor to fix that. A 100% motor teardown and reassemble on one of the more complicated bikes out there.

That carb fix was loving genius. What an awesome way to save $8 in parts by spending the entire day messing with a stick of wood and getting covered in gas.

Well when you live in Alabama and there's no retail outlets or infrastructure to transport retail items around nor communications system to support mail order parts supply, it makes sense? I guess?

Weight saving, most probably. You still need the bottom of the piston to stop it from rocking or even tumbling, but everything in between which is not required for strength is dead weight. And since they went to all the aforementioned trouble to create the cavity in the top I'm going to guess that's what it's for.

That makes sense but why not just use a slipper skirt like high performance gas engines do?

They rebuild the engine on-car in 90 minutes. Both heads off simultaneously, then one poor bastard lays underneath and has the pistons + rods fall into his 'hands'. The pistons are looked at to see how the engine is running; they don't get re-used, you just put new pistons and rings in. Not so sure about the valvetrain side of things. The gaskets get covered in copper spray.

They're an extremely simple engine; having no cooling system and no accessories besides the fuel pump and magnetos makes things a lot easier and quicker, and unlike factory engines they're intended to be taken apart quickly.

I watched a guy in the pits taking apart the clutch after a run and measuring each of the massive plates with a caliper. He had huge silver oven mitts on and they smoked all over the place when he touched a plate.

And the fuel system is literally just a pump, no injectors. It just spews fuel into the intake all the time.

I'm the monkey on a vintage racing sidecar. My biggest fear is getting stabbed in the head from behind while I'm leaned out by another rig that lost its brakes coming into a righthand hairpin after a straight. Or rolling over, maybe.

Arc flash, the poor bastard. Something in that unit arced, and the resulting explosion turned him into chunky salsa from the resulting heat and explosive pressure wave as the copper went nearly instantly from solid to gaseous state.

It's one of the things they terrified us with in my electrical training courses, because it doesn't really have any warning signs, you just screw up and explode.

What was the guy doing when it happened, though? It looked an awful lot like he was sawing something by hand.

I am sitting in the pub giggling like a maniac. This is beautiful.

Some great stuff in there.

quote:

Every time you remove a piston, you need some way of blocking the flow of oil to that journal on the crank. Strips from a pop can and a hose clamp around the journal works fine.

When the engine is distributorless, you can't just leave the spark plugs unattached, lest you burn up the coil packs, so we had the plugs still in the head firing into empty cylinders. The second time we oiled the track, we figured it out. We were igniting crackcase gasses, and blowing out the oil pan gasket. Welding some spare plugs into the trunk we could keep the proper resistive load to the coil without having an ignition source in the crankcase.

When we first fired it up on 2 cylinders, the throttle body was still trying to feed enough fuel for 4 cylinders, and we were running RICH. Cracking open the pressure regulator, and cutting a coil out of the spring seemed to drop the fuel pressure sufficiently, and the black smoke settled down, at the expense of proper fuel atomization.

I seem to recall someone going off-roading in the US, Moab, maybe? They were bimbling along in low second or first, and came to a nice, wide run down a slope, so just dipped the clutch and rolled down it, getting up to a reasonable speed and modulating with the footbrake.

The clutch disc, being attached to the input shaft of the gearbox and therby driven regardless of the pedal being dipped, did not like seeing what was later calculated as nearly 20,000rpm, and made its escape in exactly the way you would expect.

They told us about this in Dyno class at MMI. You might be tempted absentmindedly to clutch in and shift down into 1st while the dyno just whines away after doing a 4th gear pull up to something like 120mph, but don't. It's bad.

In my professional opinion, I think that you could probably chalk that up to Bosch plugs being very bad.

New Royal Enfields come from India with Bosch plugs and most of them foul up for no apparent reason in the first thousand miles or so. We replace them with NGK and never hear from them again.

On the other hand the scooter/dirt bike/atv markets have indeed been absolutely flooded.

From experience I can tell you that these things are as badly made as the SUVs. Unreliable deathtraps. My favorite is the ones -- quite a lot of them -- that say "ABS" on the front brakes. This is outright fraud, there's no such thing as ABS on any Chinese bike, and I cannot believe the attorney general doesn't crack down on these things. ABS is a genuine lifesaving feature on a bike, and lying to people about the presence of that feature should be a criminal offense. Worse than printing "AIRBAG" on a car steering wheel when there's no airbag in it.

A tank bursting is one of my greatest fears when I'm on a dive trip, especially if you're on a boat in the red sea or mediterranean where people have a rather lax attitude towards safety measures. On my last trip in the red sea we had a couple of 80l 200bar O2 tanks for mixing, and one of the shiphands would stand and smoke next to them.

I saw a How It's Made on scuba tanks recently, it blew my mind that the whole thing is made from a solid piece of extruded aluminum.

I actually ran over a squirrel with my bike once. Old bike with narrow rear end tires, 3.5" total width, probably 2" touching the ground, going 25mph. That little squirrel had such skilled paw-eye coordination he managed to run himself under that and kill himself before I could even grab the brake. If he gets reincarnated as a baseball pitcher he'll be a god.

I was working on a BMW bike the other day, not that old, 98, which had sat outside for some time. When I took the front wheel off to change the tire (which takes with it the brake rotors while the calipers stay attached to the bike) 3 of the 4 pads just fell off their metal plates. These were OEM BMW brake pads, literally fell apart just because of some rust.

So this just happened to a friend of mine's Ural. Crank broke, the flywheel went out of true and ran itself against the bearing plate bolts, and bound the clutch pack against the outer face of the transmission case, which then ate the transmission input shaft.

So Ural cranks are made of pot metal I assume?
