Hit a parked car. Comments said wheelies and burn outs are popular there. http://tmcnews.blogspot.com/2012/08/motorcycle-crash-at-quaker-steak-kills.html

See numbers above. The standard motorcycle headlight on bright high beam is dimmer than all standard and halogen and HID headlights on cars/trucks. It's not the brightness, it is where it's aimed that causes problems. There is nothing wrong with riding with high beam on. The stock motorcycle low beam is not much more than a daytime driving light.

The only thing I've ever seen is a limit by wattage, I think 55 watt for 12.0/12.8v? Typical values: H1 = 55 watts at 12.0 volts, and produces 1550 lumens ±15% when operated at 13.2 V. H2 (55 W @ 12.0 V, 1820 lm @ 13.2 V) H2 = 55 W @ 12.0 V, 1820 lm @ 13.2 V H3 = 55 W @ 12.0 V, 1450 lm ±15% H4 = not used in USA H7 = 55 W @ 12.0 V, 1500 lm ±10% @ 13.2 V H8 = 35 W @ 12.0 V, 800 lm ±15% @ 13.2 V H9 = 65 W @ 12.0 V, 2100 lm ±10% @ 13.2 V H11 = 55 W @ 12.0 V, 1350 lm ±10% @ 13.2 V HB1/9004 = 65 watts (high beam) and 45 watts (low beam) at 12.8 volts. 700 lumens on low beam and 1200 lumens on high beam. 9005/HB3 = 65 W, 12.8 V 9006/HB4 = 55 W, 12.8 V 9007/HB5 = 65/55 watts, 12.8 V D1S, D1R, D2S, D2R, D3S, D3R, D4S, and D4R HID headlamp burners produce between 2,800 and 3,500 lumens from between 35 and 38 watts of electrical power, while halogen filament headlamp bulbs produce between 700 and 2,100 lumens from between 40 and 72 watts at 12.8 V I'm not sure if US has standards for HID yet, but international has: D1R, D2R, D3R AND D4R 2800 lumens +/- 450 @ 35w @ 13.5v 2800 lumens +/- 150 @ 35w @ 13.5v CATEGORIES D1S, D2S, D3S AND D4S 3200 lumens +/- 450 @ 35w @ 13.5v 3200 lumens +/- 150 @ 35w @ 13.5v not sure what the difference in tolerance is. http://en.wikipedia.org/wiki/Headlamp http://en.wikipedia.org/wiki/Automotive_lamp_types

No part of the beam should be within two to four inches of the matching center of headlight at 25 feet. Down and to the right. For a car... I'd say if wanting light at 300 feet fully illuminating the roadway, use an auxiliary driving light to do just that. http://www.popularmechanics.com/cars/how-to/repair/1347221

definitely cool that this guy wanted to do this. warning, neo-pyschodelic - don't be hav'n no flashbacks... http://www.youtube.com/watch?v=4yfX_q1Z3oM

Ok, that was a surprise. Not totally unexpected though. Rumor is the Russians have almost completely abandoned their base/seaport in Syria. No big deal, except that's where Assad's weapons, ammo, spare parts, material supply came from. That now stops, except for what Iran can deliver. That won't be very much. Iran is in the hole for a billion dollars so far, trying to prop up Assad and Syria. Russia probably left because Syria wasn't paying for stuff anymore. Bait for the varmint. Iran needs to move troops (more than they have) to Syria or get out and drop support. Now it's getting close to the end, or close to the start, whichever way anyone wants to view it. (edit: ok, that prediction came true, now didn't it? Late September and Iran is moving troops into Syria.) Does this timing have anything to do with an upcoming US election? Of course it does, but it really shouldn't. That's just bad behavior to play that card.

Here, this is nice. A thread engagement calculator: Dissimilar materials have to be adjusted to compensate. Minimum Thread Engagement Formula and Calculation ISO Found it here: http://www.torontodrawings.com/Thread.html There's several of these, here's one for Mil Std: Minimum Length of Thread Engagement Calculator Per FED-STD-H28/2B edit: and... those are difficult to use accurately. Looking for charts that solve for us: M10 steel in steel is 6.66 threads rule of thumb and 7.4443 calculated. M10 steel in aluminum is double that by rule of thumb = 13.33 threads. In aircraft design we didn't put steel in aluminum threads, we (almost) always used steel inserts instead. And those would have been two times diameter, unless some weird design compromise. (I know, I'm contradicting myself here somewhere... live with it...)

Quite possible, both because metric threads are different from SAE, and anything with higher material properties would double as you show. Fine threads would also be different. I'm just going by the old Rockwell design manual. Which I didn't pull out to see what it would say for higher strength hardware. Personally, I always designed with 8 threads engaged where possible. Better safe than sorry. Also, aircraft design goes by minimums, in order to save weight in flight. Motorcycles appreciate the same principles. Most of them, anyway. edit: argh... the Stanford data is for cut threads. We seldom used cut threads, normally we J-formed all threads by roll forming, both exterior and interior. The J-formed threads are a lot stronger. So stock threads can be 4, cutting new ones should double where possible? edit2: oh hey, it probably should double for being steel in aluminum.... duh me... forgot about that. Here's one from Ajax fasteners in Australia: That would be 4.33 threads minimum. A standard nut only has about 4 fully formed threads anyway. That indicates something also. Fine threads would have more, but have less surface engagement. Basing thread engagement by a percent of fastener diameter is a better way of controlling the design, rather than just saying "4 threads minimum", which is only practical for SAE coarse threads, I'd guess.

Engineerd here... if it can find four good threads, it will hold for the max torque required. Six would be nice though, always good to have extra.

That's what I've been using. Or not using, lol. People are saying the new DuPont lube is thicker than the old blue can. Dunno, I've still got blue cans of the older lube. The squirt bottle is handy when it's with the bike. Smaller to carry around. I'll try the chain cleaner. Not sure about a chain drain...

A steady 45mpg on mine, and if I run elevated speeds, I get 60mpg. First time I saw that I though it was an error. But it's done it again. Dunno. I would guess the fuel flow/cam over 6000 rpm is quite different.

haha, looking around to see what's new in LED lights. PIAA offers a simple 3watt running light pair setup for $324, targeted at BMW. Really nothing more than a pair of 3 dollar LEDs from somewhere else.

Here's a link to google shopping - sorted low to high. There's a wide variety of wattages and assemblies. All are made in China, so be aware that direct purchases might take a while to ship. (And that means buy a spare or two, China stuff has a habit of burning out or breaking.) All are sold as backup lights or daylight running lights. The power output isn't high enough for an aux driving light. (The pattern spread wouldn't be approved anyway.) But I've seen a few of the multi-light strips on cars, and it does stand out. Mounted either above or below headlights, and just running these in daylight or dusk. Actually, it looks pretty cool. Used as daylight running lights. edit: My plugin app shows some of the sources as places not to buy from. Bad = AliDiscounts, ESPOW, BestCnMall, Topsellings. All others good or unknown. Lots of unknown, website sellers are popping up everywhere.

Not smoking while riding, paid off a good portion of the cost of the motorcycle. whodathunk

"I can't see it so it doesn't exist" people, not being mean here, but we run Symantec enterprise, and it reports what is found on which computers. Yes, Macs can be attacked and infected and cleaned without the user ever knowing anything happened. Granted, it's not near as bad as windows, but it's steadily rising, we've pretty much seen the trend on that. And note that if running Windows as a virtual on a Mac, all bets are off.

It wasn't one of their better models. The iMac with the vent all the way across the back side at the top is the new one. No data on that one yet, but it probably fixed the previous model's problems. Your link shows the new one, but if it was the older model, forget it. The older model of that iMac is known for overheating it's power supply and failing. If it's out of warranty it's totaled. Costs too much to fix. The older model is also known for a problem with the display. It likes to put a colored line across the screen from left to right. And then another, and then two more, and then four more, etc. Probably also an over-heating issue. Apple won't necessarily do a warranty for that problem, too many of them are doing it. Again, totaled if it happens. Apple makes good computers, but this one wasn't necessarily one of them. Regardless, people still like them and will buy them. What I'm saying, is it might already have these problems, and he wants to get rid of it. Yeah, I get to fix these when they break, but like I said, costs too much to repair sometimes. edit: guessing iMac at 1300 new, I'd go no more than 780 used. And you have to have a valid and functional warranty with that model. No exceptions.

best guess: On aluminum sprockets, there is a surface hardening to make them last, against the steel of the chain. Once that is worn through, I'm guessing the sprocket can wear very fast. This is what your old one looks like. edit: Also a sign of a low cost aluminum sprocket, that was relying on surface hardening and not the actual material strengths of the sprocket itself.

Basics: that's a polyethylene pipe (or polypropylene), and not much will stick to it for adhesives. But 3M did come out with this recently: 3M's Scotch-WeldTM Structural Plastic Adhesive DP-8005 & DP-8010 http://www.jamestowndistributors.com/userportal/show_product.do?pid=4374 This stuff is not cheap... edit: I see some suggestions that a hot glue gun with polyethylene sticks will work. Also suggested that "Goop" brand adhesive will work.

I used Google Sky on my phone. Or similar apps. And just hold the phone up to the night sky to see what I'm looking at. I know a few, but I don't have all that night sky memorized. M10 etc are Messier objects from the dawn of astronomy. http://en.wikipedia.org/wiki/Messier_object http://messier45.com/messier/index.html

Seattle? hmmm... Probably will get 41 months jail time: Hit-and-run driver gets 41 months for killing bicyclist

That's the second one I've seen this week. I saw one early Saturday morning. And I just saw one tonight. I had time to look it up, it was in Ophiuchus, (the Serpent Bearer) which was around M10 headed toward M12 & M14. Which was in the plane of the elliptic. That means it was probably a chunk of space junk falling out of orbit. Anyway, pretty unusual to see two the same week. But there are a lot of meteorites this time of year. And they happen at times that people are outside and might see them. edit: yeah yeah, I know... it's a meteor. Meteorites actually hit the ground...

Hard to say it. What was once legal, becomes suddenly illegal. I would have to question the motive. I mean if it was illegal, why did it exist before it was illegal? Why was it once legal? This is political and social posturing. Changes for other than what society might deem proper, in the guise of being proper. And that can go both ways. The effect would have been the same if something illegal was suddenly made legal. Also... I say again, careful what you wish for. Apparently Great Britain wasn't listening. They wished for a society free of violence. Or at least gun violence. It didn't happen. In this case, an average citizen was turned into a criminal, in preference to the actual criminals. Pretty much the wrong thing to do.

Shark Sprockets. Guaranteed to self sharpen the teeth.

Make sure you're getting all 530 or all 520 conversion stuff. Amazon is getting bad about not making it clear what the hell they are selling. You would have to cross check the manufacturer's part number, and even then, who knows what will get shipped. edit: some of us have found good prices, low cost chain kits here: http://www.indysuperbike.com/
