    Those are herringbone gears. The current version is now just helical (can be printed as individual gears instead of a whole assembly).

    What are you talking about. No that's not how planetary gears work. Planetary gear-sets have three input/outputs. Sun, Planets (on a carrier) and ring. A common configuration is to use one as an input, one as an output and constrain the third (many hybrids actually use two as inputs and the...

    EFI Kit DOHC

    Updated the second post. Instead of running gearing off the cam I've decided on a possibly more complicated to design, but easier to install geared crank sensor.

    EFI Kit DOHC

    The pump is being PWM controlled to regulated it's output pressure. 43.5psi is fairly standard. So input power to the pump will be fairly proportional to the required flow. Okay, I don't understand what you're asking about with the crank sensor. Maybe it's just because I've had a few drinks...

    EFI Kit DOHC

    The DOHC is timed off the crank, the coils fire twice per rev. "Speeduino" is just firmware, you need a VR condioner IC, I'm using one for the crank, and optical encoder for the cam. No need to be a smart ass. Yes you spotted the mistake, the ratio is 2.5:1 (I had thought 5:1 but that's from...

    EFI Kit DOHC

    Just a universal inline one. I have a GSL392 for testing, but I'm going to try and find a smaller one. It will be electronically regulated, so return-less, and it'll run at a vary low speed at idle.

    EFI Kit DOHC

    I'm 2-3 weeks away from a running bike. A wideband O2 sensor would be needed for some setups (and for anyone interested in tuning). However the ECU doesn't need an O2 sensor to run.

    EFI Kit DOHC

    ECU will be about the same size as the original ignition unit 2-5/8x1-7/8" (and of course replace it). Inputs: VR crank, optical cam, head temp, intake temp, TPS, barometric pressure, fuel pressure Outputs, 2 injectors, 2 coils, fuel pump. Integrated 14Point7 Spartan 2 OEM Wideband controller...

    EFI Kit DOHC

    I started working on fuel injecting a DOHC XS400 Based around a custom Speeduino based ECU. Using a throttle body from an EX300 as they are cheap, plentiful, and the injectors are the correct size. Part way through the design I realized I could sell this as a proper bolt on kit. So I figured...
