  1. Just spinning an *automotive* alternator wastes power due to friction, and has an impact on RPM changes due to inertia. The actual power needed to produce the electricity could be lower than the friction loss. In any case, it's very little. Car alternators are under 60% efficient. So let's just call it 400 watts per HP. That means a typical car alternator only uses 3-4 HP at FULL output. Some of which is lost to friction anyway. I don't think the motorcycle alternator takes any energy to simply spin, so the only power would be the magnetic drag. With an open stator, there would be nearly no magnetic drag. Voltage is potential, not power. You could generate ludicrous voltage from very little power.
  2. It probably does, and you're also correct about the potential voltage issues (hah, potential, get it?). I just don't believe there's a true benefit, and that's purely an opinion without hard data to back it up. I believe it's mental masturbation to discuss it at all, which is fine, but in reality I just don't think giving the topic any thought at all has any actual benefit. 1 HP = 746 watts, so yeah, basically nothing at all to gain. It would matter on a 50cc bike.
  3. Since I'm not sure whether you don't know how each work, or don't know why one method is preferable to the other, here's a short version of a long story... Regular shunt-type regulators just dump excess power to ground. The excess energy is wasted as heat. A series regulator interrupts the output of the alternator when it is not needed, so there's less heat and less power wasted. On a large bike the power makes no difference. The theoretical advantage for series is that they should last longer since they don't get hot. I disagree.
  4. According to DOT regs, they need to be able to withstand somewhere around 3000 PSI which is a bit over 150 degrees. I don't ride in summer and even when it's hot out the rest of the year, the topcase isn't going to hit 150 inside. I had CO2 in the tail of the XX at all times, and did ride in summer then.
  5. A friend of his sent me the link and recommendation, with a warning. "Look, he's a big fucking dork and talks too much, but he knows stuff, and he donates a shitload of time and cash to save starving kids, so he's ok." One short whiff of burning brake cleaner can lead to life long lung and organ damage. It converts to phosgene, a deadly chemical agent used in WW1 and now outlawed. Brake cleaner should not be used for welding cleaning since there's just too much risk of heating it up somehow and...boom you're fucked. You gave me a "duh" moment. If I can find a thread-on fitting that pierces these... Also, I'm not sure I'm really truly worried about it. I've never punctured a bike tire offroad, only on the road. And I've never had one come off the bead. I've plugged a few tires on the road and had mixed results, one took three plugs then held, another continued to leak. So I'm carrying a mini compressor now.
  6. I was talking about the hose to use pressure from one tire to the other. I assume everyone knows about the strap method. This would be for emergency repairs away from a tow truck, you can't pay me to deal with tires otherwise.
  7. I'm looking to do more adventure rides, mostly solo, so I'm looking at "what if" stuff. I have a mini compressor on the bike, and that high end tubeless tire repair kit that comes in the aluminum tube. But seating a bead...I carry a ratchet strap, but that's a bit of a pain. Well there's a guy who makes and sells a tire to tire connector. So you overinflate the good tire with your compressor, and then use the tire to tire hose to seat the other. Fuck yeah. I have a bunch of tire chucks, hose, and the crimp clamps/tool.
  8. I believe that was one of the bug fixes in this version, yes.
  9. The server was rebooted yesterday just before 10:17am AZ time (no DST) and down for five minutes. I'm not sure about what you mean by the other part. What browser and OS?
  10. Probably the standard zinc on all other bolts? Later today I'm going to have to compare a few bolts and see. I was also planning to see if I can use XX Frankenbolts on the KTM for bungee points.
  11. Cost? I didn't know our bolts weren't stainless until I got a bike that had been in CA humidity and all the bolts had mildly damaged finish. In AZ they stay shiny. What's in the tube?

    Fork up-grade

    That bike was torn apart in his copious shop space last time I visited. A PM might get his attention, he's not around here much.
  13. Mine was a 2000. I spent a day in a dyno room tuning out the very minor problem and tweaking top end power. We confirmed the slight lean spot using the dyno, and added fuel. It really was tiny though, and maybe I just got lucky to occasionally want the throttle and RPM at just exactly the place that makes it noticeable. Either way though, it's not something I would have spent money to fix at all. The dyno day and the programmer were free, so they could use my bike for testing.
  14. There's a touch of a flat spot in the fueling curve, and you can hit a specific point if you try where it's not smooth. But it's certainly not abrupt in any way and is easy to ride fast and accelerate out of corners with no drama at all.
  15. Yup, you don't understand how any of this works, and are making incorrect decisions based on that.
  16. Which tells me your testing was incorrect, or you got an incorrect repeater, or something like that. Or your flip phone is on a different carrier? Or you did a shit job of mounting the outside antenna.
  17. Have you considered and/or tested a cellular repeater mounted outdoors or in the attic?
  18. Next to Jethro's Large Animal Vet and BBQ.
  19. So, your pipe is too small? But yeah, an expander should do it. Pain in the ass to get the pipe/bike to a muffler shop, but you can borrow one free from Auto Zone. https://www.autozone.com/loan-a-tools/loaner-tail-pipe-expander
  20. And on the way you can pick up discount meth in Placerville!
  21. This is a great idea since CA has so much extra electrical capacity.
  22. Not at all, since it doesn't work indoors. Why does this have to be repeated? Satellite signals don't go through obstructions. It doesn't meet any of the rest of the list of needs except for being waterproof.
  23. Because satellites don't work indoors. It's also kind of expensive.
  24. You can't use them indoors. What's BWCA?
