    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.

This is the fuel level on my '79 GS850 with engine off. Is it too high? Where should it be?

The measurement should be done with the engine idling, it will be slightly lower than when the engine is not running.
 
NO. Look at he carb and the line the body makes going over the bowl is the seam youre looking at. With the engine off the fuel will be 2 to 3MM BELOW that seam. As mentioned about the bike running...I ( and many others ) have noted the difference is not of any consequence really. I use the non running bike level and move on. See the 850 service manual in the link I posted and it has pictures in the fuel sections.

Some great info there, Chuck. My fuel level is way too high so will adjust.

I have my carbs mounted on a stand so that they are level front to back and side to side...is this good for doing these measurements?

My fuel level is now 2 to 3mm below the bowl/carb junction. While I had the carbs out, I put the pilot fuel screws at 3/4 turns from bottom (I had them at about 1 turns :eek:). Bike now runs much better than before. I could tune each carb with the pilot air screws and it reacts more the way I expected it should.

Big thanks to Chuck.
