geez, I actually know what a dewar is... having designed them in a previous profession...

Heard about this one. Maxed out, I want one... I think it could run both a map switch and a manual 0-5 volt variable input (potentiometer). I'm guessing most would go for performance and economy maps with a variable input tweak. Like the variable could be for variations in air density when you're in the mountains. Although fuel injection might handle density anyway. Very cool.

btw, all performance modifications to an engine including the use of a higher octane fuel require the ignition to be retarded for best performance. Which means that if the ignition timing was wrong in the first place (already retarded), using higher octane fuel would likely create a slight but noticeable increase in power. edit: arghhh, that was so wrong, it's all modifications EXCEPT use of higher octane fuel. Higher octane fuel needs advancing the timing in order to maximize the power output. Everything else requires retarding the ignition. So that would be "if the ignition timing was wrong in the first place (already advanced)..." I'll go away now...

yes and no? The higher octane delays the ignition temperature, preventing "ping". But the higher octane burns faster? Creating more heat? The delay is not relevant in an engine that isn't detonating the fuel early, being that the ignition of the fuel still takes place at the correct moment. It's preventing an EARLY ignition that would create the ping of detonation by compression rather than spark.

Bet it tastes like pork... besides, exactly how do they know it tastes like human? http://www.damninteresting.com/?p=168 http://www.strangenewproducts.com/2005/09/tofu-that-tastes-like-human-flesh.html That's what she said...

exceptions are: carbon build-up creates higher compression = higher octane needed compression leaks create lower compression = lower octane needed either/both = repair needed The temperature that a given fuel type burns (ignites) at, and the speed of the flame front propagation in the combustion chamber at a given compression ratio, along with the combustion properties of the fuel type, will result in different overall amounts of power and/or heat generated. It's complicated... but variations away from the correct fuel octane will usually but not always produce less horsepower/torque. besides, it's what everyone said; your owner's manual has it right. geez, I just read what I said, it makes my head hurt... edit: just to annoy people --> air density and humidity also change the results

keep it simple? Remove the ones you can, and paint over the ones you can't? I mean tape off the tank sticker and paint only that. Or put a sticker of your choice over the tank sticker, even easier. Vinyl appliques for motorcycles, there's a million of them. edit: What about a black tank bra thingy? Would it cover that area of the tank?

Made me think... hmmm, deadly weapon....time for some math... 3400 pound vehicle traveling at 80 mph equals 1545.5 kilograms at 35.76 meters per second kinetic energy is Ek=1/2 x m x v2 the kinetic energy is 988175.39 joules an equivalent handgun firing at a typical 800fps would have what size bullet? 988175.39 = 1/2 x m x 800 x 800 answer is 3.088 kilograms = 6.81 pounds that's a hand cannon indeed more math, a liter bike traveling at 185mph is the equivalent of what speed for a 3400 pound car? 450 lb bike + 180 lb rider + 25 lb gear = 655 pounds 655 pounds = 297.10 kilograms 185mph = 82.695 meters per second kinetic energy is 1015853.68 joules answer is 36.26 meters per second = 81.22 mph somebody check my math, it's early in the morning and no coffee yet...

You made me think... We didn't used to have any gear at all. It wasn't invented yet. Gear was either a leather jacket or a jeans jacket and a cheap ass helmet. And it was wise to wear both. Gloves and boots were nothing special. Granted it only helped against road rash, but it was on everyone's mind. We spent our time concentrating on riding skills and tactics, knowing that was the only thing that would get us out of a collision. Times change, but I still would rather count on skill and tactics to get out of trouble. Yeah, most of those old bikes would only barely do 100mph. And we didn't do that very often, it's part of "tactics".

dude, this is art... A unique creation A labor of personal intensity And is how inventors invent the poor become rich and not everyone can do it

That's what she said...

Cool, you have just joined that elite group of bike riders, who build their own trinkle chargers. We used to do that back-in-the-day. Something about starving-student-with-more-time-than-money. Back then we didn't have the discrete devices to master control of the circuit. Ok, geez... we were lucky we had transistors... Advanced circuit maybe has switchable hi-lo amperage rating? It never ends...

Damn it, every time I see this thread I want a damn cold beer....

Excellent, one last stupid question... Are you really dropping stepdown voltage to 12v, or something a little higher?

So what's the estimated output amperage at the battery? I'm asking rather than calculating... way too lazy...

Indeed, it is a step down transformer, duh me...

Excuse my ignorance, I've not dug into a circuit for a long time. But isn't an LT317 limited to a 40V input to output voltage differential?

Yeah, apparently somewhere, a 12yo ingested an 85cc motorbike...

And then there is the FedEx truck, blame it all on them. Dang I wish they would lighten up like the UPS guy. UPS knows me, and will do anything to make sure I get my stuff. FedEx makes me wait, skips the drop, makes me sign, won't drop if I leave signature, won't drop at a neighbor, etc. A neighbor gal got a FedEx box dropped off that wasn't hers, runs out chasing the guy, who runs for the truck, and takes off... She throws the box and hits the back of his truck... I love it...

odd critters... one guy on campus had a very large iguana. He built a shelf for it over top of the front door. That's where the iguana liked to hang out. It would slap strangers with his tail when they came in. Didn't have to lock the door, had an iguana-on-guard-duty. No kidding, it was like 5 or 6 feet, not counting tail. A regular dragon.

That's really cool. I've never actually heard of anyone doing it. Golf balls, that's funny. New thought is that centripetal motion might not stick an object at the lowest point after all. The constant motion of the tire would turn the round objects that are inside and move them constantly. The end effect is balanced in motion.

Factory stuff likes to use acrylic enamel or acrylic urethanes that "shrink" when they dry. That eliminates or reduces the orange peel. They do that with the addition of a catalyst that hardens the paint by chemical reaction. Old style acrylic lacquers air dry, when the volatiles (thinner) evaporate from the paint. It takes longer. Heat speeds it up, either way. And what Max Power said... And each type of paint is dried and sanded differently. A little different anyway. Difference in length of drying time or type of sanding/polishing grit used. Usually whatever the paint manufacturer recommends is good. Show finish lacquer isn't sanded/polished the same way as factory enamel. Yeah, I've painted a few motorcycles...

You rock, give that gal rep...

Wait... you want a nearly endangered wild animal that will only want to eat eucalyptus leaves. Good luck with that! Having had to look up how to spell eucalyptus, I now also know that male kolas have a bifuricated penis (double). As well as female koalas have doubles too, including uterus. As do all marsupials. Hence their nick name "Double-barreled little dag dudes" And just when you thought learning anything new wouldn't happen.
