  1. Have fun everyone. Good thing we are not working on improving fire, we all would have food poisoning. Enjoy!

  3. 1. Put a large hose clamp on the filter. 2. Use a turn signal in place of the fuse to troubleshoot. This article is old, but so is electricity. https://www.yamaha-motor-university.com/ymu/motorsports/advertising/YMU%20Service%20Limit/docs/States%20of%20a%20Wire%20December%202013.pdf Plenty of help for wiring problem here.
  4. Normally bicycles don't exceed the speeds needed for the "counter-steer" dynamic to be in affect. This is based on chassis geometry, contact patch, traction, and speed. Let us not bring tricycle or two-wheel leading dynamics into this. CoG becomes a vastly more important component with those things.
  5. I bought a MyECU because of this, the other tools were not as prevalent back then. Stalling at stop lights made the original ECU useless during commuting.
  6. This is up in my office, but there is 3 more images and the titles are slightly different. Give me a day or two and I'll post it. It brings me back to the real world really quick when things go awol.
  7. FAKE NEWS!!!! Sorry. Just voicing an ignorant view point. In reality the video does illustrate a simple principle but also shows some other serious rider flaws. Like rolling off throttle and grabbing a big handful of front brake. If you really want to increase your skill as a rider, sign up for a few trackdays or go racing. You will quickly learn what your motorcycle is really capable of. You can train your self to trust your tires (with in their limits of course), countersteer, and give it MORE throttle (stabilizes the chassis and transfer load to the rear tire). Of course all of this is opposite of what our untrained brain wants us to do.
  8. If i read the original post out loud it is all about the horn to me. Cause, effect, where to start looking for a problem.
  9. I get stuck at the third and fourth sentence I hope everyone here has a excellent new year!
  10. Roy, it has nothing to do with the battery or the charging system, let alone the changes in resistance to the starting circuit during pull-up. A fused circuit will only move so much current, based on the total circuit resistance, not what the power supply can provide. The problem occurs when the horn button is pressed, how about we focus on that problem and the voltage drops that happen therein. Your wiring diagrams here are awesome and your advice on this site is always outstanding. I wasn't really challenging your aptitude nor trying to dive into discourse about ohms law. I didn't take the time to look at a diagram in this case, but my advice was based on experience as a long time technician. To the OP, disconnect the horn. Start it, and press the horn button. What happens? If everything works like it should, replace the horn. While there can be other issues this is a quick and simple starting point.
  11. What the battery can put out is illrelevent, the total circuit resistance is the important consideration. If the fuse has 0.3Ω, the relay 0.8Ω, the button 0.4Ω and the horn 0.1Ω, what happens in that fused circuit.
  12. Sounds like a horn driver that is stuck. When it gets stick it causes a direct short ( or near that) and pulls the voltage on the circuit low.
  13. I little side project I was involved in. It has been neglected unfortunately. The main page has a few other articles if you are curious. https://www.yamaha-motor-university.com/ymu/motorsports/advertising/YMU%20Service%20Limit/index.html
  14. Here is three relevant articles. https://www.yamaha-motor-university.com/ymu/motorsports/advertising/YMU%20Service%20Limit/docs/Three%20Ignition%20System%20Types%20September%202012.pdf https://www.yamaha-motor-university.com/ymu/motorsports/advertising/YMU%20Service%20Limit/docs/Troubleshooting%20TCI%20Ignition%20Systems%20October%202012.pdf https://www.yamaha-motor-university.com/ymu/motorsports/advertising/YMU%20Service%20Limit/docs/Ignition%20Coils%20July%202013.pdf
