    1990 650LX Carb Settings?

    Can someone tell me a good baseline to start with on the mixture screws on this machine? I want to get it in the right ballpark before I start trying to tune it 100%. I looked through the online manuals that are mentioned on this site but I didn't see any manuals relating to this particular model.

    Thanks.

    John

    Yamaha 650 - Low Speed – 1-1/8 +/- ¼
    High Speed – 1–1/8 +/- ¼

    I have not worked on this peticular model, I pulled this off a list I have with all makes and their settings.

    Thank you very much Bill. I'm hoping to head out on it tomorrow afternoon.
