    heyy all i just fitted my dr70 kit to my streetmagic, and it appears to be running lean but i cant seem to work out which screw is the mixture screw, its a 14mm keihen, ive got a workshop manual but i cant seem to find anything about how to increase/decrease the mixture. the screws it says i have are
    throttle stop screw
    air screw

    sorry for being such a noob but im not that well trained in carbs

    cheers all

    air screw is your idle mixture.. anything other than idle will be the needle/main jet to ajust mixture. if it runs at idle but dies when you touch the throttle its the needle/mj and you need to play with rollers.
