    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.

Float Height question

Hello all,

1980 GS750E
I could probably figure this out within a week or so of thinking about it but need an answer sooner. According to the clymer manual float height should be between 21.4mm and 24.somethingmm (it is out in my shoip). question is this... is lower then 21.4mm considered to rich or over 24.somethingmm. My floats were around 20mm and my bike was running rich, would it be correct to say that increasing to 22 mm would lean it out?

Re: Float Height question

Float height is measured when holding the carbs upside down. It is the distance between the float bowl gasket surface (without gasket) to the highest point on the float. The higher the fuel level is in the float bowl, the richer the bike will run, Decreasing the measurement then means the fuel level in the bowl will be higher. So yes, if your float level is now at 20 mm and you reset it to 22 mm, that would be a leaner setting. BTW, I set the floats in my 750 to 24-25 mm.

Thanks Earl, I knew it would be much faster this way! If she is still rich I will wrestle the carbs out again and reset them to 24.
