  1. A suggestion to try before you remove the side plate: push a screwdriver into the switch hole onto the cam plate. If you can feel the springiness of the banana plate bending, then it could mean the circlip is off.
  2. Is it possible that the circlip (Item 13) (you call it a Seeger Ring) has come off, allowing the cam wheel to move inboard? Or the nut holding item 20 post is not tight? That would allow both wheels to move inboard. (But only a tiny bit)
  3. Did you wind the switch in to fix a leak? Try turning the neutral switch out 1/6 turn intervals until it works normally, then fit a seal washer of that thickness. The switch turns on the green light when the plunger extends into a depression in the face of the lower cam wheel.
  4. Joe says his gears are made of EN24T steel. This British standard is similar to AISI 4340. It's pretty good stuff that could be heat treated up to ultra high strength. "T" condition has good strength yet can still be machined. (tensile strength 850/1000 N/mm² / 123-145 KSI)
  5. This is very interesting for me. I know my timing chain is sloppy; when I point a timing light into the little inspection hole to see the flywheel mark, I can see the mark jiggling up and down. Since I have to fix this sometime, I have to ask whether you think a new chain and tensioner would achieve the same improvement as a gear set? I expect that it would be a lot cheaper.
  6. I carry one under the seat in case I need an emergency top up. A downside is it unseats the valve in the wheel, so as you fit or remove it you lose a tiny bit of pressure. If you leave one on permanently, you add to potential pressure leak sources, and may upset wheel balance. Agree on angle valve stems, but Cash1000 had one leak after the thread stripped. Get good quality valve stems. I'm ambivalent on nitrogen. It is well established that eliminating water vapor and oxygen is helpful. Water vapor gives greater tire pressure changes with heat; important to avoid in racing. Oxygen causes oxidation: brittle rubber, rim rust, seal deterioration, and faster leak rate. The mandatory requirement for nitrogen in commercial aviation is valid in that industry where tires are 800% overloaded (intermittantly) in comparison to cars. This does not mean nitrogen is needed for cars or bikes. However consumer tests show a small but real reduction in pressure loss over several months for nitrogen inflated tires. This is good, but Dalton's law of partial pressures tells us that eventually other gasses will diffuse into a nitrogen inflated tire, so purging and re-inflating after several years could be needed. My conclusion is you could choose to use nitrogen if it is free, but checking tire pressure is more important.
  7. Meinolf gave some advice on tuning to go with his map here: https://www.v11lemans.com/forums/index.php?/topic/21701-ecu-bin-maps/#elControls_233775_menu I used his map on my Ti ECU, and have never been inclined to revert to the Ti map I saved.
  8. If you find water, you should change the fuel filter, and clear the screen on the fuel tap inlet. I had brown fuzz through my bike fuel system that may have come from disintegrating filter paper.
  9. Fuel pumped past the injectors returns to the tank through the pressure regulator. You can drain any water/old gas at the bottom of the tank by disconnecting the hose at the regulator, and collecting the fuel as you turn on and off the ign switch. About half a cup will come out each prime cycle.

    Allite Super Magnesium "weighing 30% less than aluminum by volume and being both stiffer and stronger pound for pound". This is a misleading claim. Allite's website states their alloy strength is greater than steel (not in this universe) but they don't give numbers. Be careful not to slip in the snake oil - this alloy is likely to be weaker than the aluminum alloy in the factory side plates. To get equivalent strength you need to make magnesium alloy side plates thicker/bulkier to make up for the weaker material. Allite claim "shock absorbing properties" but this means it is more elastic (lower Young's modulus). This means a more floppy swing arm mount, unless made thicker/bulkier. You should listen to Pete, and also look at the material properties.
  11. Douglas Noel Adams was a Brit who wrote "The Hitchhiker's Guide to the Galaxy" among other stories. A great storyteller who improved my life. If you find that you are taking yourself too seriously, his books are the antidote.
  12. There's a good discussion on setting the sensor clearance here: https://www.v11lemans.com/forums/index.php?/topic/21021-guzzisti-friendship/#elControls_240669_menu
  13. Shimming V11 RPM Sensor.pdf Josh, I suspect that your phase/revolution sensor PN GU01721600 is bad. It is a coil of very fine wire inside a resin body. It can work ok when cold, but become open circuit as the engine warms up. If the connection in the coil wire is intermittent, then the engine will be erratic.

  14. Many in NZ say "kays". Although as a country with a lot of sheep, we could start using Sheppies. Douglas Adams said a Sheppy is the closest distance at which sheep remain picturesque (about 1.4 kays).
  15. I'm still happy with the Shorai battery in my bike. https://www.v11lemans.com/forums/index.php?/topic/19799-pc545-still-the-way-to-go/&do=findComment&comment=247107
