    cb360 lean/rich issue

    on my cb360 engine, its fouling plugs out, so that should mean rich, right? but it also runs better with the choke on, which should mean lean, right? does this make any sense to anyone, and does anyone know what the issue is?

    maybe this cb it has bad rings to foul the plugs and a main jet with a part obstruction make the lean condition.

    They do that with pods
    If you jet for top end, it goes super rich at transition from primary to secondary main jet (when slide starts to lift)
    If you don't re-jet, it runs fine to 4~4.5k then starts to go lean and probably won't go over 7k
    I dabble in rocket science, when I\'m not picking my nose
    The other night I gave my girlfriend an orgasm, but, she spat it back at me

    it only reaches about 3.5-4k rpm before it breaks up and sputters. runs fine at half throttle, once you go full it loses al power

    You'll have to list the 'modifications' you've done
    Did you shim needles?
