    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Carb EFI Conversion: VM or CV?

Not surprised you couldn't find examples of a successful post conversion. I'm sure there are some, because people have been doing it on old cars since the 90s.
Problem is most new bike engine heads are designed for EFI with short intake runs with steep downhill angles. Very different from a GS with it's horizontal intake.
Building a proper EFI system is only the first part of the conversion project. The long hard part is endless testing and programming a working fuel map.
There needs to be an oxygen sensor located in the best place of the exhaust system.
Starting from point 0, you got a long road ahead before you got a good thing going.


Not sure I agree. V&H have made this easy now that they offer a Dyna type pickup that bolts to a GS engine. The fuel map is easy with closed loop, you just need enough fuel to get it started, then it is straight forward.

I am doing two 1150's now and a 82 Katana after that. I am using Hayabusa Throttle bodies since they are cheap and easy to find.

Good luck

Hi Prostar1316,
Please post a thread with pictures with your progress and specifications.
Very interested to compare and see your versions of EFI on GS motors.
Cheers Andrew.
