    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.

Will turning the mixture screw in (3 turns out to 2 turns out) richen the mixture or make it more lean?

Turning the mixture screw out will richen things up and in will make it leaner. I presume on your 850 as your 750 has an air screw and a fuel screw but no mixture screw
 
Hi,

As I understand the CV carbs, the "idle mixture screw" really doesn't control the mixture itself. The mixture (air/fuel ratio) is set by the carb internals. However, the "idle mixture screw" will determine 'how much' of the idle mixture the engine receives at idle. At three turns out the cylinder receives more of the mixture than at two turns out.


Thank you for your indulgence,

Thanks. The reason for my question is I still have the feeling that I am not quite getting all the acceleration I should be getting in 1-3rd gear. That being said, I haven't ridden a totally stock bike for a long time. My cafe gs750 has a lot of acceleration through all gears. It's exhaust is open and not baffled at all. The gs850 that I'm questioning is my everyday commuter bike. Runs great at highway speeds, but it doesn't seem to have all the power/acceleration that I would expect. This doesn't stop me from riding it nearly daily, but it is a frustration. It does get better when the bike gets warmer, but still is present after warm up.

I've done all the things necessary to make it run well. The ten things, carbs dipped, etc. This problem is not horrible, but still troubles me a bit. I'd like to feel all the power the bike has.

Thanks for the help.
